What to do for Primary Hyperparathyroidism ? | - Primary hyperparathyroidism is a disorder of the parathyroid glands, in which one or more of the parathyroid glands are overactive. As a result, the gland releases too much parathyroid hormone (PTH). - High PTH levels trigger the bones to release increased calcium into the blood, causing blood calcium levels to rise above normal. T he loss of calcium from bones may weaken the bones. In response to high blood calcium levels, the kidneys excrete more calcium in the urine, which can lead to kidney stones. - Most people with primary hyperparathyroidism have no symptoms. When symptoms appear, they are often mild and nonspecific, such as muscle weakness, fatigue, increased need for sleep, feelings of depression, or aches and pains in bones and joints. - People with more severe primary hyperparathyroidism may have symptoms such as loss of appetite, nausea, vomiting, constipation, confusion or impaired thinking and memory, and increased thirst and urination. - Health care providers diagnose primary hyperparathyroidism when a person has high blood calcium and PTH levels. - Surgery to remove the overactive parathyroid gland or glands is the only definitive treatment for the disorder. When performed by experienced endocrine surgeons, surgery cures primary hyperparathyroidism in more than 95 percent of operations. Some people who have mild primary hyperparathyroidism may not need immediate or even any surgery and can be safely monitored. People with primary hyperparathyroidism due to familial hypocalciuric hypercalcemia should not have surgery. |
What is (are) Kidney Dysplasia ? | Kidney dysplasia is a condition in which the internal structures of one or both of a fetus kidneys do not develop normally while in the womb. During normal development, two thin tubes of muscle called ureters grow into the kidneys and branch out to form a network of tiny structures called tubules. The tubules collect urine as the fetus grows in the womb. In kidney dysplasia, the tubules fail to branch out completely. Urine that would normally flow through the tubules has nowhere to go. Urine collects inside the affected kidney and forms fluid-filled sacs called cysts. The cysts replace normal kidney tissue and prevent the kidney from functioning.
Kidney dysplasia can affect one kidney or both kidneys. Babies with severe kidney dysplasia affecting both kidneys generally do not survive birth. Those who do survive may need the following early in life:
- blood-filtering treatments called dialysis - a kidney transplant
Children with dysplasia in only one kidney have normal kidney function if the other kidney is unaffected. Those with mild dysplasia of both kidneys may not need dialysis or a kidney transplant for several years.
Kidney dysplasia is also called renal dysplasia or multicystic dysplastic kidney. |
What is (are) Kidney Dysplasia ? | The kidneys are two bean-shaped organs, each about the size of a fist. They are located just below the rib cage, one on each side of the spine. Every day, the two kidneys filter about 120 to 150 quarts of blood to produce about 1 to 2 quarts of urine, which is composed of wastes and extra fluid. Children produce less urine than adultsthe amount they produce depends on their age. The urine flows from the kidneys to the bladder through the two ureters, one on each side of the bladder. The bladder stores urine. The muscles of the bladder wall remain relaxed while the bladder fills with urine. As the bladder fills to capacity, signals sent to the brain tell a person to find a toilet soon. When the bladder empties, urine flows out of the body through a tube called the urethra, located at the bottom of the bladder.
The kidneys, ureters, bladder, and urethra are parts of the urinary tract. More information is provided in the NIDDK health topics, the kidneys and the urinary tract. |
What causes Kidney Dysplasia ? | Genetic factors can cause kidney dysplasia. Genes pass information from both parents to the child and determine the childs traits. Sometimes, parents may pass a gene that has changed, or mutated, causing kidney dysplasia.
Genetic syndromes that affect multiple body systems can also cause kidney dysplasia. A syndrome is a group of symptoms or conditions that may seem unrelated yet are thought to have the same genetic cause. A baby with kidney dysplasia due to a genetic syndrome might also have problems of the digestive tract, nervous system, heart and blood vessels, muscles and skeleton, or other parts of the urinary tract.
A baby may also develop kidney dysplasia if his or her mother takes certain prescription medications during pregnancy, such as some used to treat seizures and high blood pressure. A mothers use of illegal drugs, such as cocaine, during pregnancy may also cause kidney dysplasia in her unborn child. |
How many people are affected by Kidney Dysplasia ? | Kidney dysplasia is a common condition. Scientists estimate that kidney dysplasia affects about one in 4,000 babies.1 This estimate may be low because some people with kidney dysplasia are never diagnosed with the condition. About half of the babies diagnosed with this condition have other urinary tract defects.2 |
What are the symptoms of Kidney Dysplasia ? | Many babies with kidney dysplasia in only one kidney have no signs of the condition. In some cases, the affected kidney may be enlarged at birth and may cause pain. |
What are the complications of Kidney Dysplasia ? | The complications of kidney dysplasia can include
- hydronephrosis of the working kidney. A baby with kidney dysplasia in only one kidney might have other urinary tract defects. When other defects in the urinary tract block the flow of urine, the urine backs up and causes the kidneys and ureters to swell, a condition called hydronephrosis. If left untreated, hydronephrosis can damage the working kidney and reduce its ability to filter blood. Kidney damage may lead to chronic kidney disease (CKD) and kidney failure. - a urinary tract infection (UTI). A urine blockage may increase a babys chance of developing a UTI. Recurring UTIs can also lead to kidney damage. - high blood pressure. - a slightly increased chance of developing kidney cancer.
More information is provided in the NIDDK health topics, urine blockage in newbornsand UTIs in children. |
How to diagnose Kidney Dysplasia ? | Health care providers may be able to diagnose kidney dysplasia during a womans pregnancy using a fetal ultrasound, also called a fetal sonogram. Ultrasound uses a device, called a transducer, that bounces safe, painless sound waves off organs to create an image of their structure. Fetal ultrasound is a test done during pregnancy to create images of the fetus in the womb. A specially trained technician performs the procedure in a health care providers office, an outpatient center, or a hospital, and an obstetrician or a radiologist interprets the images. An obstetrician is a doctor who specializes in pregnancy and childbirth. A radiologist is a doctor who specializes in medical imaging. The patientin this case, the fetus motherdoes not need anesthesia for this procedure. The images can show defects in the fetus kidneys and other parts of the urinary tract.
Health care providers do not always diagnose kidney dysplasia before a baby is born. After birth, health care providers often diagnose kidney dysplasia during an evaluation of the child for a UTI or another medical condition. A health care provider uses ultrasound to diagnose kidney dysplasia after the baby is born. |
What are the treatments for Kidney Dysplasia ? | If the condition is limited to one kidney and the baby has no signs of kidney dysplasia, no treatment may be necessary. However, the baby should have regular checkups that include
- checking blood pressure. - testing blood to measure kidney function. - testing urine for albumin, a protein most often found in blood. Albumin in the urine may be a sign of kidney damage. - performing periodic ultrasounds to monitor the damaged kidney and to make sure the functioning kidney continues to grow and remains healthy. |
How to prevent Kidney Dysplasia ? | Researchers have not found a way to prevent kidney dysplasia caused by genetic factors or certain genetic syndromes. Pregnant women can prevent kidney dysplasia by avoiding the use of certain prescription medications or illegal drugs during pregnancy. Pregnant women should talk with their health care provider before taking any medications during pregnancy. |
What is the outlook for Kidney Dysplasia ? | The long-term outlook for a child with kidney dysplasia in only one kidney is generally good. A person with one working kidney, a condition called solitary kidney, can grow normally and may have few, if any, health problems.
The affected kidney may shrink as the child grows. By age 10,3 the affected kidney may no longer be visible on x-ray or ultrasound. Children and adults with only one working kidney should have regular checkups to test for high blood pressure and kidney damage. A child with urinary tract problems that lead to failure of the working kidney may eventually need dialysis or a kidney transplant.
More information is provided in the NIDDK health topics, solitary kidney, dialysis, and kidney transplants. |
What is the outlook for Kidney Dysplasia ? | The long-term outlook for a child with kidney dysplasia in both kidneys is different from the long-term outlook for a child with one dysplastic kidney. A child with kidney dysplasia in both kidneys
- is more likely to develop CKD. - needs close follow-up with a pediatric nephrologista doctor who specializes in caring for children with kidney disease. Children who live in areas that dont have a pediatric nephrologist available can see a nephrologist who cares for both children and adults. - may eventually need dialysis or a kidney transplant. |
What to do for Kidney Dysplasia ? | Researchers have not found that eating, diet, and nutrition play a role in causing or preventing kidney dysplasia. |

What is (are) Urinary Incontinence in Men ? | Urinary incontinence is the loss of bladder control, resulting in the accidental leakage of urine from the body. For example, a man may feel a strong, sudden need, or urgency, to urinate just before losing a large amount of urine, called urgency incontinence.
UI can be slightly bothersome or totally debilitating. For some men, the chance of embarrassment keeps them from enjoying many activities, including exercising, and causes emotional distress. When people are inactive, they increase their chances of developing other health problems, such as obesity and diabetes. |
What is (are) Urinary Incontinence in Men ? | The urinary tract is the bodys drainage system for removing urine, which is composed of wastes and extra fluid. In order for normal urination to occur, all parts in the urinary tract need to work together in the correct order.
Kidneys. The kidneys are two bean-shaped organs, each about the size of a fist. They are located just below the rib cage, one on each side of the spine. Every day, the kidneys filter about 120 to 150 quarts of blood to produce about 1 to 2 quarts of urine. The kidneys work around the clock; a person does not control what they do.
Ureters. Ureters are the thin tubes of muscleone on each side of the bladderthat carry urine from each of the kidneys to the bladder.
Bladder. The bladder, located in the pelvis between the pelvic bones, is a hollow, muscular, balloon-shaped organ that expands as it fills with urine. Although a person does not control kidney function, a person does control when the bladder empties. Bladder emptying is known as urination. The bladder stores urine until the person finds an appropriate time and place to urinate. A normal bladder acts like a reservoir and can hold 1.5 to 2 cups of urine. How often a person needs to urinate depends on how quickly the kidneys produce the urine that fills the bladder. The muscles of the bladder wall remain relaxed while the bladder fills with urine. As the bladder fills to capacity, signals sent to the brain tell a person to find a toilet soon. During urination, the bladder empties through the urethra, located at the bottom of the bladder.
Three sets of muscles work together like a dam, keeping urine in the bladder between trips to the bathroom.
The first set is the muscles of the urethra itself. The area where the urethra joins the bladder is the bladder neck. The bladder neck, composed of the second set of muscles known as the internal sphincter, helps urine stay in the bladder. The third set of muscles is the pelvic floor muscles, also referred to as the external sphincter, which surround and support the urethra.
To urinate, the brain signals the muscular bladder wall to tighten, squeezing urine out of the bladder. At the same time, the brain signals the sphincters to relax. As the sphincters relax, urine exits the bladder through the urethra. |
What is (are) Urinary Incontinence in Men ? | The prostate is a walnut-shaped gland that is part of the male reproductive system. The prostate has two or more lobes, or sections, enclosed by an outer layer of tissue. Located in front of the rectum and just below the bladder, the prostate surrounds the urethra at the neck of the bladder and supplies fluid that goes into semen. |
What causes Urinary Incontinence in Men ? | Urinary incontinence in men results when the brain does not properly signal the bladder, the sphincters do not squeeze strongly enough, or both. The bladder muscle may contract too much or not enough because of a problem with the muscle itself or the nerves controlling the bladder muscle. Damage to the sphincter muscles themselves or the nerves controlling these muscles can result in poor sphincter function. These problems can range from simple to complex.
A man may have factors that increase his chances of developing UI, including
- birth defectsproblems with development of the urinary tract - a history of prostate cancersurgery or radiation treatment for prostate cancer can lead to temporary or permanent UI in men
UI is not a disease. Instead, it can be a symptom of certain conditions or the result of particular events during a mans life. Conditions or events that may increase a mans chance of developing UI include
- benign prostatic hyperplasia (BPH)a condition in which the prostate is enlarged yet not cancerous. In men with BPH, the enlarged prostate presses against and pinches the urethra. The bladder wall becomes thicker. Eventually, the bladder may weaken and lose the ability to empty, leaving some urine in the bladder. The narrowing of the urethra and incomplete emptying of the bladder can lead to UI. - chronic coughinglong-lasting coughing increases pressure on the bladder and pelvic floor muscles. - neurological problemsmen with diseases or conditions that affect the brain and spine may have trouble controlling urination. - physical inactivitydecreased activity can increase a mans weight and contribute to muscle weakness. - obesityextra weight can put pressure on the bladder, causing a need to urinate before the bladder is full. - older agebladder muscles can weaken over time, leading to a decrease in the bladders capacity to store urine.
More information is provided in the NIDDK health topics, Nerve Disease and Bladder Control and Prostate Enlargement: Benign Prostatic Hyperplasia. |
What is (are) Urinary Incontinence in Men ? | The types of UI in men include
- urgency incontinence - stress incontinence - functional incontinence - overflow incontinence - transient incontinence
Urgency Incontinence
Urgency incontinence happens when a man urinates involuntarily after he has a strong desire, or urgency, to urinate. Involuntary bladder contractions are a common cause of urgency incontinence. Abnormal nerve signals might cause these bladder contractions.
Triggers for men with urgency incontinence include drinking a small amount of water, touching water, hearing running water, or being in a cold environmenteven if for just a short whilesuch as reaching into the freezer at the grocery store. Anxiety or certain liquids, medications, or medical conditions can make urgency incontinence worse.
The following conditions can damage the spinal cord, brain, bladder nerves, or sphincter nerves, or can cause involuntary bladder contractions leading to urgency incontinence:
- Alzheimers diseasea disorder that affects the parts of the brain that control thought, memory, and language - injury to the brain or spinal cord that interrupts nerve signals to and from the bladder - multiple sclerosisa disease that damages the material that surrounds and protects nerve cells, which slows down or blocks messages between the brain and the body - Parkinsons diseasea disease in which the cells that make a chemical that controls muscle movement are damaged or destroyed - strokea condition in which a blocked or ruptured artery in the brain or neck cuts off blood flow to part of the brain and leads to weakness, paralysis, or problems with speech, vision, or brain function
Urgency incontinence is a key sign of overactive bladder. Overactive bladder occurs when abnormal nerves send signals to the bladder at the wrong time, causing its muscles to squeeze without enough warning time to get to the toilet. More information is provided in the NIDDK health topic, Nerve Disease and Bladder Control.
Stress Incontinence
Stress incontinence results from movements that put pressure on the bladder and cause urine leakage, such as coughing, sneezing, laughing, or physical activity. In men, stress incontinence may also occur
- after prostate surgery - after neurologic injury to the brain or spinal cord - after trauma, such as injury to the urinary tract - during older age
Functional Incontinence
Functional incontinence occurs when physical disability, external obstacles, or problems in thinking or communicating keep a person from reaching a place to urinate in time. For example, a man with Alzheimers disease may not plan ahead for a timely trip to a toilet. A man in a wheelchair may have difficulty getting to a toilet in time. Arthritispain and swelling of the jointscan make it hard for a man to walk to the restroom quickly or open his pants in time.
Overflow Incontinence
When the bladder doesnt empty properly, urine spills over, causing overflow incontinence. Weak bladder muscles or a blocked urethra can cause this type of incontinence. Nerve damage from diabetes or other diseases can lead to weak bladder muscles; tumors and urinary stones can block the urethra. Men with overflow incontinence may have to urinate often, yet they release only small amounts of urine or constantly dribble urine.
Transient Incontinence
Transient incontinence is UI that lasts a short time. Transient incontinence is usually a side effect of certain medications, drugs, or temporary conditions, such as
- a urinary tract infection (UTI), which can irritate the bladder and cause strong urges to urinate - caffeine or alcohol consumption, which can cause rapid filling of the bladder - chronic coughing, which can put pressure on the bladder - constipationhard stool in the rectum can put pressure on the bladder - blood pressure medications that can cause increased urine production - short-term mental impairment that reduces a mans ability to care for himself - short-term restricted mobility |
How many people are affected by Urinary Incontinence in Men ? | Urinary incontinence occurs in 11 to 34 percent of older men. Two to 11 percent of older men report daily UI.1 Although more women than men develop UI, the chances of a man developing UI increase with age because he is more likely to develop prostate problems as he ages. Men are also less likely to speak with a health care professional about UI, so UI in men is probably far more common than statistics show. Having a discussion with a health care professional about UI is the first step to fixing this treatable problem. |
How to diagnose Urinary Incontinence in Men ? | Men should tell a health care professional, such as a family practice physician, a nurse, an internist, or a urologista doctor who specializes in urinary problemsthey have UI, even if they feel embarrassed. To diagnose UI, the health care professional will
- take a medical history - conduct a physical exam - order diagnostic tests
Medical History
Taking a medical history can help a health care professional diagnose UI. He or she will ask the patient or caretaker to provide a medical history, a review of symptoms, a description of eating habits, and a list of prescription and over-the-counter medications the patient is taking. The health care professional will ask about current and past medical conditions.
The health care professional also will ask about the mans pattern of urination and urine leakage. To prepare for the visit with the health care professional, a man may want to keep a bladder diary for several days beforehand. Information that a man should record in a bladder diary includes
- the amount and type of liquid he drinks - how many times he urinates each day and how much urine is released - how often he has accidental leaks - whether he felt a strong urge to go before leaking - what he was doing when the leak occurred, for example, coughing or lifting - how long the symptoms have been occurring
Use the Daily Bladder Diary to prepare for the appointment.
The health care professional also may ask about other lower urinary tract symptoms that may indicate a prostate problem, such as
- problems starting a urine stream - problems emptying the bladder completely - spraying urine - dribbling urine - weak stream - recurrent UTIs - painful urination
Physical Exam
A physical exam may help diagnose UI. The health care professional will perform a physical exam to look for signs of medical conditions that may cause UI. The health care professional may order further neurologic testing if necessary.
Digital rectal exam. The health care professional also may perform a digital rectal exam. A digital rectal exam is a physical exam of the prostate and rectum. To perform the exam, the health care professional has the man bend over a table or lie on his side while holding his knees close to his chest. The health care professional slides a gloved, lubricated finger into the patients rectum and feels the part of the prostate that lies in front of the rectum. The digital rectal exam is used to check for stool or masses in the rectum and to assess whether the prostate is enlarged or tender, or has other abnormalities. The health care professional may perform a prostate massage during a digital rectal exam to collect a sample of prostate fluid that he or she can test for signs of infection.
The health care professional may diagnose the type of UI based on the medical history and physical exam, or he or she may use the findings to determine if a man needs further diagnostic testing.
Diagnostic Tests
The health care professional may order one or more of the following diagnostic tests based on the results of the medical history and physical exam:
- Urinalysis. Urinalysis involves testing a urine sample. The patient collects a urine sample in a special container at home, at a health care professionals office, or at a commercial facility. A health care professional tests the sample during an office visit or sends it to a lab for analysis. For the test, a nurse or technician places a strip of chemically treated paper, called a dipstick, into the urine. Patches on the dipstick change color to indicate signs of infection in urine. - Urine culture. A health care professional performs a urine culture by placing part of a urine sample in a tube or dish with a substance that encourages any bacteria present to grow. A man collects the urine sample in a special container in a health care professionals office or a commercial facility. The office or facility tests the sample onsite or sends it to a lab for culture. A health care professional can identify bacteria that multiply, usually in 1 to 3 days. A health care professional performs a urine culture to determine the best treatment when urinalysis indicates the man has a UTI. More information is provided in the NIDDK health topic, Urinary Tract Infections in Adults. - Blood test. A blood test involves drawing blood at a health care professionals office or a commercial facility and sending the sample to a lab for analysis. The blood test can show kidney function problems or a chemical imbalance in the body. The lab also will test the blood to assess the level of prostate-specific antigen, a protein produced by prostate cells that may be higher in men with prostate cancer. - Urodynamic testing. Urodynamic testing includes a variety of procedures that look at how well the bladder and urethra store and release urine. A health care professional performs urodynamic tests during an office visit or in an outpatient center or a hospital. Some urodynamic tests do not require anesthesia; others may require local anesthesia. Most urodynamic tests focus on the bladders ability to hold urine and empty steadily and completely; they may include the following: - uroflowmetry, which measures how rapidly the bladder releases urine - postvoid residual measurement, which evaluates how much urine remains in the bladder after urination - reduced urine flow or residual urine in the bladder, which often suggests urine blockage due to BPH
More information is provided in the NIDDK health topic, Urodynamic Testing. |
What are the treatments for Urinary Incontinence in Men ? | Treatment depends on the type of UI.
Urgency Incontinence
As a first line of therapy for urgency incontinence, a health care professional may recommend the following techniques to treat a mans problem:
- behavioral and lifestyle changes - bladder training - pelvic floor exercises - urgency suppression
If those treatments are not successful, the following additional measures may help urgency incontinence:
- medications - electrical nerve stimulation - bulking agents - surgery
A health care professional may recommend other treatments for men with urgency incontinence caused by BPH. More information is provided in the NIDDK health topic, Prostate Enlargement: Benign Prostatic Hyperplasia.
Behavioral and lifestyle changes. Men with urgency incontinence may be able to reduce leaks by making behavioral and lifestyle changes:
- Eating, diet, and nutrition. Men with urgency incontinence can change the amount and type of liquid they drink. A man can try limiting bladder irritantsincluding caffeinated drinks such as tea or coffee and carbonated beveragesto decrease leaks. Men also should limit alcoholic drinks, which can increase urine production. A health care professional can help a man determine how much he should drink based on his health, how active he is, and where he lives. To decrease nighttime trips to the restroom, men may want to stop drinking liquids several hours before bed. - Engaging in physical activity. Although a man may be reluctant to engage in physical activity when he has urgency incontinence, regular exercise is important for good overall health and for preventing and treating UI. - Losing weight. Men who are overweight should talk with a health care professional about strategies for losing weight, which can help improve UI. - Preventing constipation. Gastrointestinal (GI) problems, especially constipation, can make urinary tract health worse and can lead to UI. The opposite is also true: Urinary problems, such as UI, can make GI problems worse. More information about how to prevent constipation through diet and physical activity is provided in the NIDDK health topic, Constipation.
To Help Prevent Bladder Problems, Stop Smoking People who smoke should stop. Quitting smoking at any age promotes bladder health and overall health. Smoking increases a persons chance of developing stress incontinence, as it increases coughing. Some people say smoking worsens their bladder irritation. Smoking causes most cases of bladder cancer. People who smoke for many years have a higher risk of bladder cancer than nonsmokers or those who smoke for a short time.2 People who smoke should ask for help so they do not have to try quitting alone. Call 1-800-QUITNOW (1-800-784-8669) for more information.
Bladder training. Bladder training is changing urination habits to decrease incidents of UI. The health care professional may suggest a man use the restroom at regular timed intervals, called timed voiding, based on the mans bladder diary. A man can gradually lengthen the time between trips to the restroom to help stretch the bladder so it can hold more urine.
Pelvic floor muscle exercises. Pelvic floor muscle, or Kegel, exercises involve strengthening pelvic floor muscles. Strong pelvic floor muscles hold in urine more effectively than weak muscles. A man does not need special equipment for Kegel exercises. The exercises involve tightening and relaxing the muscles that control urine flow. Pelvic floor exercises should not be performed during urination. A health care professional can help a man learn proper technique. More information is provided in the NIDDK health topic, Kegel Exercise Tips.
Men also may learn how to perform Kegel exercises properly by using biofeedback. Biofeedback uses special sensors to measure bodily functions, such as muscle contractions that control urination. A video monitor displays the measurements as graphs, and sounds indicate when the man is using the correct muscles. The health care professional uses the information to help the man change abnormal function of the pelvic floor muscles. At home, the man practices to improve muscle function. The man can perform the exercises while lying down, sitting at a desk, or standing up. Success with pelvic floor exercises depends on the cause of UI, its severity, and the mans ability to perform the exercises.
Urgency suppression. By using certain techniques, a man can suppress the urge to urinate, called urgency suppression. Urgency suppression is a way for a man to train his bladder to maintain control so he does not have to panic about finding a restroom. Some men use distraction techniques to take their mind off the urge to urinate. Other men find taking long, relaxing breaths and being still can help. Doing pelvic floor exercises also can help suppress the urge to urinate.
Medications. Health care professionals may prescribe medications that relax the bladder, decrease bladder spasms, or treat prostate enlargement to treat urgency incontinence in men.
- Antimuscarinics. Antimuscarinics can help relax bladder muscles and prevent bladder spasms. These medications include oxybutynin (Oxytrol), tolterodine (Detrol), darifenacin (Enablex), trospium (Sanctura), fesoterodine (Toviaz), and solifenacin (VESIcare). They are available in pill, liquid, and patch form. - Tricyclic antidepressants. Tricyclic antidepressants such as imipramine (Tofranil) can calm nerve signals, decreasing spasms in bladder muscles. - Alpha-blockers. Terazosin (Hytrin), doxazosin (Cardura), tamsulosin (Flomax), alfuzosin (Uroxatral), and silodosin (Rapaflo) are used to treat problems caused by prostate enlargement and bladder outlet obstruction. These medications relax the smooth muscle of the prostate and bladder neck, which lets urine flow normally and prevents abnormal bladder contractions that can lead to urgency incontinence. - 5-alpha reductase inhibitors. Finasteride (Proscar) and dutasteride (Avodart) block the production of the male hormone dihydrotestosterone, which accumulates in the prostate and may cause prostate growth. These medications may help to relieve urgency incontinence problems by shrinking an enlarged prostate. - Beta-3 agonists. Mirabegron (Myrbetriq) is a beta-3 agonist a person takes by mouth to help prevent symptoms of urgency incontinence. Mirabegron suppresses involuntary bladder contractions. - Botox. A health care professional may use onabotulinumtoxinA (Botox), also called botulinum toxin type A, to treat UI in men with neurological conditions such as spinal cord injury or multiple sclerosis. Injecting Botox into the bladder relaxes the bladder, increasing storage capacity and decreasing UI. A health care professional performs the procedure during an office visit. A man receives local anesthesia. The health care professional uses a cystoscope to guide the needle for injecting the Botox. Botox is effective for up to 10 months.3
Electrical nerve stimulation. If behavioral and lifestyle changes and medications do not improve symptoms, a urologist may suggest electrical nerve stimulation as an option to prevent UI, urinary frequencyurination more often than normaland other symptoms. Electrical nerve stimulation involves altering bladder reflexes using pulses of electricity. The two most common types of electrical nerve stimulation are percutaneous tibial nerve stimulation and sacral nerve stimulation.4
- Percutaneous tibial nerve stimulation uses electrical stimulation of the tibial nerve, which is located in the ankle, on a weekly basis. The patient receives local anesthesia for the procedure. In an outpatient center, a urologist inserts a battery-operated stimulator beneath the skin near the tibial nerve. Electrical stimulation of the tibial nerve prevents bladder activity by interfering with the pathway between the bladder and the spinal cord or brain. Although researchers consider percutaneous tibial nerve stimulation safe, they continue to study the exact ways that it prevents symptoms and how long the treatment can last. - Sacral nerve stimulation involves implanting a battery-operated stimulator beneath the skin in the lower back near the sacral nerve. The procedure takes place in an outpatient center using local anesthesia. Based on the patients feedback, the health care professional can adjust the amount of stimulation so it works best for that individual. The electrical pulses enter the body for minutes to hours, two or more times a day, either through wires placed on the lower back or just above the pubic areabetween the navel and the pubic hair. Sacral nerve stimulation may increase blood flow to the bladder, strengthen pelvic muscles that help control the bladder, and trigger the release of natural substances that block pain. The patient can turn the stimulator on or off at any time.
A patient may consider getting an implanted device that delivers regular impulses to the bladder. A urologist places a wire next to the tailbone and attaches it to a permanent stimulator under the skin.
Bulking agents. A urologist injects bulking agents, such as collagen and carbon spheres, near the urinary sphincter to treat incontinence. The bulking agent makes the tissues thicker and helps close the bladder opening. Before the procedure, the health care professional may perform a skin test to make sure the man doesnt have an allergic reaction to the bulking agent. A urologist performs the procedure during an office visit. The man receives local anesthesia. The urologist uses a cystoscopea tubelike instrument used to look inside the urethra and bladderto guide the needle for injection of the bulking agent. Over time, the body may slowly eliminate certain bulking agents, so a man may need to have injections again.
Surgery. As a last resort, surgery to treat urgency incontinence in men includes the artificial urinary sphincter (AUS) and the male sling. A health care professional performs the surgery in a hospital with regional or general anesthesia. Most men can leave the hospital the same day, although some may need to stay overnight.
- AUS. An AUS is an implanted device that keeps the urethra closed until the man is ready to urinate. The device has three parts: a cuff that fits around the urethra, a small balloon reservoir placed in the abdomen, and a pump placed in the scrotumthe sac that holds the testicles. The cuff contains a liquid that makes it fit tightly around the urethra to prevent urine from leaking. When it is time to urinate, the man squeezes the pump with his fingers to deflate the cuff. The liquid moves to the balloon reservoir and lets urine flow through the urethra. When the bladder is empty, the cuff automatically refills in the next 2 to 5 minutes to keep the urethra tightly closed. - Male sling. A health care professional performs a sling procedure, also called urethral compression procedure, to add support to the urethra, which can sometimes better control urination. Through an incision in the tissue between the scrotum and the rectum, also called the perineum, the health care professional uses a piece of human tissue or mesh to compress the urethra against the pubic bone. The surgeon secures the ends of the tissue or mesh around the pelvic bones. The lifting and compression of the urethra sometimes provides better control over urination.
Stress Incontinence
Men who have stress incontinence can use the same techniques for treating urgency incontinence.
Functional Incontinence
Men with functional incontinence may wear protective undergarments if they worry about reaching a restroom in time. These products include adult diapers or pads and are available from drugstores, grocery stores, and medical supply stores. Men who have functional incontinence should talk to a health care professional about its cause and how to prevent or treat functional incontinence.
Overflow Incontinence
A health care professional treats overflow incontinence caused by a blockage in the urinary tract with surgery to remove the obstruction. Men with overflow incontinence that is not caused by a blockage may need to use a catheter to empty the bladder. A catheter is a thin, flexible tube that is inserted through the urethra into the bladder to drain urine. A health care professional can teach a man how to use a catheter. A man may need to use a catheter once in a while, a few times a day, or all the time. Catheters that are used continuously drain urine from the bladder into a bag that is attached to the mans thigh with a strap. Men using a continuous catheter should watch for symptoms of an infection.
Transient Incontinence
A health care professional treats transient incontinence by addressing the underlying cause. For example, if a medication is causing increased urine production leading to UI, a health care professional may try lowering the dose or prescribing a different medication. A health care professional may prescribe bacteria-fighting medications called antibiotics to treat UTIs. |
How to prevent Urinary Incontinence in Men ? | People who smoke should stop. Quitting smoking at any age promotes bladder health and overall health. Smoking increases a persons chance of developing stress incontinence, as it increases coughing. Some people say smoking worsens their bladder irritation. Smoking causes most cases of bladder cancer. People who smoke for many years have a higher risk of bladder cancer than nonsmokers or those who smoke for a short time.2 People who smoke should ask for help so they do not have to try quitting alone. Call 1-800-QUITNOW (1-800-784-8669) for more information. |
What to do for Urinary Incontinence in Men ? | - Urinary incontinence (UI) is the loss of bladder control, resulting in the accidental leakage of urine from the body. - The urinary tract is the bodys drainage system for removing urine, which is composed of wastes and extra fluid. - Every day, the kidneys filter about 120 to 150 quarts of blood to produce about 1 to 2 quarts of urine. - To urinate, the brain signals the muscular bladder wall to tighten, squeezing urine out of the bladder. At the same time, the brain signals the sphincters to relax. As the sphincters relax, urine exits the bladder through the urethra. - UI results when the brain does not properly signal the bladder, the sphincters do not squeeze strongly enough, or both. - Urgency incontinence happens when a man urinates involuntarily after he has a strong desire, or urgency, to urinate. - Stress incontinence results from movements that put pressure on the bladder and cause urine leakage, such as coughing, sneezing, laughing, or physical activity. - Functional incontinence occurs when physical disability, external obstacles, or problems in thinking or communicating keep a person from reaching a place to urinate in time. - When the bladder doesnt empty properly, urine spills over, causing overflow incontinence. Weak bladder muscles or a blocked urethra can cause this type of incontinence. - Transient incontinence is UI that lasts a short time. Transient incontinence is usually a side effect of certain medications, drugs, or temporary conditions. - UI occurs in 11 to 34 percent of older men. - Men should tell a health care professional, such as a family practice physician, a nurse, an internist, or a urologist, they have UI, even if they feel embarrassed. - Treatment depends on the type of UI. Some types of treatment include behavioral and lifestyle changes, bladder training, pelvic floor exercises, and urgency suppression. - People who smoke should stop. Quitting smoking at any age promotes bladder health and overall health. |
What is (are) What I need to know about Interstitial Cystitis/Painful Bladder Syndrome ? | Interstitial cystitis*painful bladder syndrome (IC/PBS) is one of several conditions that causes bladder pain and a need to urinate frequently and urgently. Some doctors have started using the term bladder pain syndrome (BPS) to describe this condition.
Your bladder is a balloon-shaped organ where your body holds urine. When you have a bladder problem, you may notice certain signs or symptoms.
*See Pronounciation Guide for tips on how to say the words in bold type. |
What are the symptoms of What I need to know about Interstitial Cystitis/Painful Bladder Syndrome ? | Signs of bladder problems include
- Urgency. The feeling that you need to go right now! Urgency is normal if you haven't been near a bathroom for a few hours or if you have been drinking a lot of fluids. But you may have a problem if you have strong urges before your bladder has had time to fill. All of a sudden, you feel a strong urge to go. At times, you may even have an accident because the urge strikes so quickly you don't have time to find a bathroom. - Frequency. The feeling that you need to go much more often than anyone else. Doctors and nurses use the term void, which means to empty the bladder. Most people void between four and seven times a day. Drinking large amounts of fluid can cause more frequent voiding. Taking blood pressure medicines called diuretics, or water pills, can also cause more frequent voiding. If you void more than eight times a day, and you dont take diuretics or drink large amounts of fluid, it may be the sign of a problem. - Pain. The feeling of more than discomfort when you need to go. Having a full bladder may be uncomfortable, but it should not be painful. You may have a problem if you feel burning or sharp pain in your bladder or urethrathe opening where urine leaves the body.
Some people may have pain without urgency or frequency. Others have urgency and frequency without pain. |
What causes What I need to know about Interstitial Cystitis/Painful Bladder Syndrome ? | Many different problems can cause urgency, frequency, and bladder pain. Just a few of them are
- infections - bowel disorders - endometriosistissue that normally lines the womb that appears in other places outside of the womb - bladder cancer
Your doctor will ask you questions and run tests to find the cause of your bladder problems. Usually, the doctor will find that you have either an infection or an overactive bladder. But urgency, frequency, and pain are not always caused by infection.
Sometimes the cause is hard to find. If all the test results are normal and all other diseases are ruled out, your doctor may find that you have IC/PBS. |
Who is at risk for What I need to know about Interstitial Cystitis/Painful Bladder Syndrome? ? | Both men and women can get IC/PBS, though twice as many women are affected as men. It can occur at any age, but it is most common in middle age.
People with IC/PBS rarely have bladder pain all the time. The pain usually comes and goes as the bladder fills and then empties. The pain may go away for weeks or months and then return. People with IC/PBS sometimes refer to an attack of bladder pain as a flare or flare-up. Stress may bring on a flare-up of symptoms in someone who has IC/PBS. But stress does not cause a person to get IC/PBS. |
How to diagnose What I need to know about Interstitial Cystitis/Painful Bladder Syndrome ? | Finding the cause of bladder pain may require several tests.
While tests may aid your doctor in making a diagnosis of IC/PBS, a careful review of your symptoms and a physical exam in the office are generally the most important parts of the evaluation. |
What are the treatments for What I need to know about Interstitial Cystitis/Painful Bladder Syndrome ? | No one treatment for IC/PBS has been found that works for everyone. Your doctor or nurse will work with you to find a treatment plan that meets your special needs. The plan may include diet and lifestyle changes, bladder retraining, activity and exercise, physical therapy, and various types of medicines. You should expect some treatment failures along the way, but, with time, you and your doctor or nurse should find a treatment that gives you some relief and helps you cope with your disease.
Diet and Lifestyle Changes
Some people with IC/PBS find that certain foods or drinks bring on their symptoms. Others find no link between symptoms and what they eat.
Learning what foods cause symptoms for you may require some trial and error. Keep a food diary and note the times you have bladder pain. The diary might reveal that your flare-ups always happen, for example, after you eat tomatoes or oranges.
Some doctors recommend taking an antacid medicine with meals. The medicine reduces the amount of acid that gets into the urine.
If you make changes to your diet, remember to eat a variety of healthy foods.
Bladder Retraining
Bladder retraining is a way to help your bladder hold more urine. People with bladder pain often get in the habit of using the bathroom as soon as they feel pain or urgency. They then feel the need to go before the bladder is really full. The body may get used to frequent voiding. Bladder retraining helps your bladder hold more urine before signaling the urge to urinate.
Keep a bladder diary to track how you are doing. Start by noting the times when you void. Note how much time goes by between voids. For example, you may find that you return to the bathroom every 40 minutes.
Try to stretch out the time between voids. If you usually void every 40 minutes, try to wait at least 50 minutes before you go to the bathroom.
If your bladder becomes painful, you may use the bathroom. But you may find that your first urge to use the bathroom goes away if you ignore it. Find ways to relax or distract yourself when the first urge strikes.
After a few days, you may be able to stretch the time out to 60 or 70 minutes, and you may find that the urge to urinate does not return as soon.
Activity
If you have IC/PBS, you may feel the last thing you want to do is exercise. But many people feel that easy activities like walking or gentle stretching exercises help relieve symptoms.
Physical Therapy
Your doctor or nurse may suggest pelvic exercises. The pelvic muscles hold the bladder in place and help control urination. The first step is to find the right muscle to squeeze. A doctor, nurse, or physical therapist can help you. One way to find the muscles is to imagine that you are trying to stop passing gas. Squeeze the muscles you would use. If you sense a "pulling" feeling, you have found the right muscles for pelvic exercises.
You may need exercises to strengthen those muscles so that it's easier to hold in urine. Or you may need to learn to relax your pelvic muscles if tense muscles are part of your bladder pain.
Some physical therapists specialize in helping people with pelvic pain. Ask your doctor or nurse to help you find a professional trained in pelvic floor physical therapy.
Reducing Stress
Stress doesn't cause IC/PBS. But stress can trigger painful flare-ups in someone who has IC/PBS. Learning to reduce stress in your life by making time for relaxation every day may help control some symptoms of IC/PBS.
Oral Medicines
Pain pills like aspirin, ibuprofen, or acetominophen can help control mild bladder pain. Advil and Motrin are examples of ibuprofen. Tylenol is an example of acetominophen. Talk with your doctor if you feel you need a stronger pain medicine.
Your doctor may recommend a medication, pentosan polysulfate sodium, sold as Elmiron, which is approved for treating the pain of IC/PBS. You may need to take this medicine for up to 6 months before you notice improvement. Elmiron does not work for everyone, but some people with IC/PBS have found relief taking it. You need a doctor's order for Elmiron. If you don't notice improvement of your symptoms in 6 months, this medicine is not likely to work.
Researchers are also looking at other kinds of medicines. Medicines that treat heartburn might help bladder symptoms by reducing the amount of acid made in the body. Muscle relaxants can keep the bladder from squeezing at the wrong time. Keeping the bladder muscle relaxed helps ease the symptoms of IC/PBS.
Bladder Stretching
The doctor may stretch the bladder by filling it with liquid. You will be given an anesthetic to prevent pain and help relax your bladder muscles. Some patients have said their symptoms were helped after this treatment.
Bladder Medicines
Many patients who have IC/PBS find relief after a treatment in which their bladders are filled with a liquid medicine. The doctor guides a tube into your bladder and slowly fills the bladder with a liquid that eases irritation of the bladder wall. The liquid may be a compound called DMSO or a solution that contains heparin and a pain medicine called lidocaine.
You will keep the liquid in your bladder for about 15 minutes and then release it. You can have this treatment once every week or every other week for 1 or 2 months. You may not feel any better until the third or fourth treatment.
Nerve Stimulation
If you have tried diet changes, exercise, and medicines and nothing seems to help, you may wish to think about nerve stimulation. This treatment sends mild electrical pulses to the nerves that control the bladder.
At first, you may try a system that sends the pulses through electrodes placed on your skin. If this therapy works for you, you may consider having a device put in your body. The device delivers small pulses of electricity to the nerves around the bladder.
For some patients, nerve stimulation relieves bladder pain as well as urinary frequency and urgency. For others, the treatment relieves frequency and urgency but not pain. For still other patients, it does not work.
Scientists are not sure why nerve stimulation works. Some believe that the electrical pulses block the pain signals carried in the nerves. If your brain doesn't receive the nerve signal, you don't feel the pain. Others believe that the electricity releases endorphins, which are hormones that block pain naturally.
Surgery
As a last resort, your doctor might suggest surgery to remove part or all of the bladder. Surgery does not cure the pain of IC/PBS in all cases, but if you have tried every other option and your pain is still unbearable, surgery might be considered.
Talk with your doctor and family about the possible benefits and side effects. |
What to do for What I need to know about Interstitial Cystitis/Painful Bladder Syndrome ? | - Bladder problems have many possible causes. - Your doctor will need to do tests to find the cause of your bladder problems. If all the test results are normal, you may have IC/PBS. - No one treatment option for IC/PBS works for everybody. - Treatments for IC/PBS may include changing your diet and exercising. - Medicines for IC/PBS may be taken by mouth or put directly into the bladder through a tube by a doctor. - Nerve stimulation helps some people with IC/PBS. - Surgery is a last resort for treating IC/PBS. |
What is (are) Vesicoureteral Reflux ? | Vesicoureteral reflux is the abnormal flow of urine from the bladder to the upper urinary tract. The urinary tract is the bodys drainage system for removing wastes and extra water. The urinary tract includes two kidneys, two ureters, a bladder, and a urethra. Blood flows through the kidneys, and the kidneys filter out wastes and extra water, making urine. The urine travels down two narrow tubes called the ureters. The urine is then stored in a balloonlike organ called the bladder. When the bladder empties, urine flows out of the body through a tube called the urethra at the bottom of the bladder.
In VUR, urine may flow backrefluxinto one or both ureters and, in some cases, to one or both kidneys. VUR that affects only one ureter and kidney is called unilateral reflux, and VUR that affects both ureters and kidneys is called bilateral reflux. |
Who is at risk for Vesicoureteral Reflux? ? | Vesicoureteral reflux is more common in infants and young children, but older children and even adults can be affected. About 10 percent of children have VUR.1 Studies estimate that VUR occurs in about 32 percent of siblings of an affected child. This rate may be as low as 7 percent in older siblings and as high as 100 percent in identical twins. These findings indicate that VUR is an inherited condition.2 |
What is (are) Vesicoureteral Reflux ? | The two types of VUR are primary and secondary. Most cases of VUR are primary and typically affect only one ureter and kidney. With primary VUR, a child is born with a ureter that did not grow long enough during the childs development in the womb. The valve formed by the ureter pressing against the bladder wall does not close properly, so urine refluxes from the bladder to the ureter and eventually to the kidney. This type of VUR can get better or disappear as a child gets older. As a child grows, the ureter gets longer and function of the valve improves.
Secondary VUR occurs when a blockage in the urinary tract causes an increase in pressure and pushes urine back up into the ureters. Children with secondary VUR often have bilateral reflux. VUR caused by a physical defect typically results from an abnormal fold of tissue in the urethra that keeps urine from flowing freely out of the bladder.
VUR is usually classified as grade I through V, with grade I being the least severe and grade V being the most severe. |
What are the symptoms of Vesicoureteral Reflux ? | In many cases, a child with VUR has no symptoms. When symptoms are present, the most common is a urinary tract infection (UTI). VUR can lead to infection because urine that remains in the childs urinary tract provides a place for bacteria to grow. Studies estimate that 30 percent of children and up to 70 percent of infants with a UTI have VUR.2 |
What are the complications of Vesicoureteral Reflux ? | When a child with VUR gets a UTI, bacteria can move into the kidney and lead to scarring. Scarring of the kidney can be associated with high blood pressure and kidney failure. However, most children with VUR who get a UTI recover without long-term complications. |
How to diagnose Vesicoureteral Reflux ? | The most common tests used to diagnose VUR include
- Voiding cystourethrogram (VCUG). VCUG is an x-ray image of the bladder and urethra taken during urination, also called voiding. The bladder and urethra are filled with a special dye, called contrast medium, to make the urethra clearly visible. The x-ray machine captures a video of the contrast medium when the child urinates. The procedure is performed in a health care providers office, outpatient center, or hospital by an x-ray technician supervised by a radiologista doctor who specializes in medical imagingwho then interprets the images. Anesthesia is not needed, but sedation may be used for some children. This test can show abnormalities of the inside of the urethra and bladder. - Radionuclide cystogram (RNC). RNC is a type of nuclear scan that involves placing radioactive material into the bladder. A scanner then detects the radioactive material as the child urinates or after the bladder is empty. The procedure is performed in a health care providers office, outpatient center, or hospital by a specially trained technician, and the images are interpreted by a radiologist. Anesthesia is not needed, but sedation may be used for some children. RNC is more sensitive than VCUG but does not provide as much detail of the bladder anatomy. - Abdominal ultrasound. Ultrasound uses a device, called a transducer, that bounces safe, painless sound waves off organs to create an image of their structure. An abdominal ultrasound can create images of the entire urinary tract, including the kidneys and bladder. The procedure is performed in a health care providers office, outpatient center, or hospital by a specially trained technician, and the images are interpreted by a radiologist; anesthesia is not needed. Ultrasound may be used before VCUG or RNC if the childs family or health care provider wants to avoid exposure to x-ray radiation or radioactive material.
Testing is usually done on
- infants diagnosed during pregnancy with urine blockage affecting the kidneys - children younger than 5 years of age with a UTI - children with a UTI and fever, called febrile UTI, regardless of age - males with a UTI who are not sexually active, regardless of age or fever - children with a family history of VUR, including an affected sibling
More information about urine blockage in infants is provided in the NIDDK health topic, Urine Blockage in Newborns.
VUR is an unlikely cause of UTI in some children, so these tests are not done until other causes of UTI are ruled out for
- children 5 years of age and older with a UTI - children with a UTI but no fever - sexually active males with a UTI |
How to diagnose Vesicoureteral Reflux ? | Following diagnosis, children with VUR should have a general medical evaluation that includes blood pressure measurement, as high blood pressure is an indicator of kidney damage. If both kidneys are affected, a childs blood should be tested for creatininea waste product of normal muscle breakdown. Healthy kidneys remove creatinine from the blood; when the kidneys are damaged, creatinine builds up in the blood. The urine may be tested for the presence of protein and bacteria. Protein in the urine is another indication of damaged kidneys.
- having to urinate often or suddenly - long periods of time between bathroom visits - daytime wetting - pain in the penis or perineumthe area between the anus and genitals - posturing to prevent wetting - constipationa condition in which a child has fewer than two bowel movements in a week; the bowel movements may be painful - fecal incontinenceinability to hold stool in the colon and rectum, which are parts of the large intestine |
What are the treatments for Vesicoureteral Reflux ? | The standard treatment for primary VUR has included prompt treatment of UTIs and long-term use of antibiotics to prevent UTIs, also called antimicrobial prophylaxis, until VUR goes away on its own. Antibiotics are bacteria-fighting medications. Surgery has also been used in certain cases.
Several studies have raised questions about long-term use of antibiotics for prevention of UTIs. The studies found little or no effect on prevention of kidney damage. Long-term use may also make the child resistant to the antibiotic, meaning the medication does not work as well, and the child may be sicker longer and may need to take medications that are even stronger.
- children younger than 1 year of age continuous antibiotics should be used if a child has a history of febrile UTI or VUR grade III through V that was identified through screening - children older than 1 year of age with BBDcontinuous antibiotics should be used while BBD is being treated - children older than 1 year of age without BBDcontinuous antibiotics can be used at the discretion of the health care provider but is not automatically recommended; however, UTIs should be promptly treated
Deflux, a gellike liquid containing complex sugars, is an alternative to surgery for treatment of VUR. A small amount of Deflux is injected into the bladder wall near the opening of the ureter. This injection creates a bulge in the tissue that makes it harder for urine to flow back up the ureter. The health care provider uses a special tube to see inside the bladder during the procedure. Deflux injection is an outpatient procedure done under general anesthesia, so the child can go home the same day. |
What are the treatments for Vesicoureteral Reflux ? | Secondary VUR is treated by removing the blockage causing the reflux. Treatment may involve
- surgery - antibiotics - intermittent catheterizationdraining the bladder by inserting a thin tube, called a catheter, through the urethra to the bladder |
What to do for Vesicoureteral Reflux ? | Eating, diet, and nutrition have not been shown to play a role in causing or preventing VUR. |

What is (are) Hemolytic Uremic Syndrome in Children ? | Hemolytic uremic syndrome, or HUS, is a kidney condition that happens when red blood cells are destroyed and block the kidneys' filtering system. Red blood cells contain hemoglobinan iron-rich protein that gives blood its red color and carries oxygen from the lungs to all parts of the body.
When the kidneys and glomerulithe tiny units within the kidneys where blood is filteredbecome clogged with the damaged red blood cells, they are unable to do their jobs. If the kidneys stop functioning, a child can develop acute kidney injurythe sudden and temporary loss of kidney function. Hemolytic uremic syndrome is the most common cause of acute kidney injury in children. |
What is (are) Hemolytic Uremic Syndrome in Children ? | The kidneys are two bean-shaped organs, each about the size of a fist. They are located just below the rib cage, one on each side of the spine. Every day, the two kidneys filter about 120 to 150 quarts of blood to produce about 1 to 2 quarts of urine, composed of wastes and extra fluid. Children produce less urine than adults and the amount produced depends on their age. The urine flows from the kidneys to the bladder through tubes called ureters. The bladder stores urine. When the bladder empties, urine flows out of the body through a tube called the urethra, located at the bottom of the bladder. |
What causes Hemolytic Uremic Syndrome in Children ? | The most common cause of hemolytic uremic syndrome in children is an Escherichia coli (E. coli) infection of the digestive system. The digestive system is made up of the gastrointestinal, or GI, tracta series of hollow organs joined in a long, twisting tube from the mouth to the anusand other organs that help the body break down and absorb food.
Normally, harmless strains, or types, of E. coli are found in the intestines and are an important part of digestion. However, if a child becomes infected with the O157:H7 strain of E. coli, the bacteria will lodge in the digestive tract and produce toxins that can enter the bloodstream. The toxins travel through the bloodstream and can destroy the red blood cells. E.coli O157:H7 can be found in
- undercooked meat, most often ground beef - unpasteurized, or raw, milk - unwashed, contaminated raw fruits and vegetables - contaminated juice - contaminated swimming pools or lakes
Less common causes, sometimes called atypical hemolytic uremic syndrome, can include
- taking certain medications, such as chemotherapy - having other viral or bacterial infections - inheriting a certain type of hemolytic uremicsyndrome that runs in families
More information about foodborne illnesses and the digestive system is provided in the NIDDK health topic, foodborne illnesses. |
What are the symptoms of Hemolytic Uremic Syndrome in Children ? | A child with hemolytic uremic syndrome may develop signs and symptoms similar to those seen with gastroenteritisan inflammation of the lining of the stomach, small intestine, and large intestine such as
- vomiting - bloody diarrhea - abdominal pain - fever and chills - headache
As the infection progresses, the toxins released in the intestine begin to destroy red blood cells. When the red blood cells are destroyed, the child may experience the signs and symptoms of anemiaa condition in which red blood cells are fewer or smaller than normal, which prevents the body's cells from getting enough oxygen.
Signs and symptoms of anemia may include
- fatigue, or feeling tired - weakness - fainting - paleness
As the damaged red blood cells clog the glomeruli, the kidneys may become damaged and make less urine. When damaged, the kidneys work harder to remove wastes and extra fluid from the blood, sometimes leading to acute kidney injury.
Other signs and symptoms of hemolytic uremic syndrome may include bruising and seizures.
When hemolytic uremic syndrome causes acute kidney injury, a child may have the following signs and symptoms:
- edemaswelling, most often in the legs, feet, or ankles and less often in the hands or face - albuminuriawhen a child's urine has high levels of albumin, the main protein in the blood - decreased urine output - hypoalbuminemiawhen a child's blood has low levels of albumin - blood in the urine
Seek Immediate Care Parents or caretakers should seek immediate care for a child experiencing any urgent symptoms, such as - unusual bleeding - swelling - extreme fatigue - decreased urine output - unexplained bruises |
How to diagnose Hemolytic Uremic Syndrome in Children ? | A health care provider diagnoses hemolytic uremic syndrome with
- a medical and family history - a physical exam - urine tests - a blood test - a stool test - kidney biopsy
Medical and Family History
Taking a medical and family history is one of the first things a health care provider may do to help diagnose hemolytic uremic syndrome.
Physical Exam
A physical exam may help diagnose hemolytic uremic syndrome. During a physical exam, a health care provider most often
- examines a child's body - taps on specific areas of the child's body
Urine Tests
A health care provider may order the following urine tests to help determine if a child has kidney damage from hemolytic uremic syndrome.
Dipstick test for albumin. A dipstick test performed on a urine sample can detect the presence of albumin in the urine, which could mean kidney damage. The child or caretaker collects a urine sample in a special container in a health care provider's office or a commercial facility. For the test, a nurse or technician places a strip of chemically treated paper, called a dipstick, into the child's urine sample. Patches on the dipstick change color when albumin is present in the urine.
Urine albumin-to-creatinine ratio. A health care provider uses this measurement to estimate the amount of albumin passed into the urine over a 24-hour period. The child provides a urine sample during an appointment with the health care provider. Creatinine is a waste product that is filtered in the kidneys and passed in the urine. A high urine albumin-to-creatinine ratio indicates that the kidneys are leaking large amounts of albumin into the urine.
Blood Test
A blood test involves drawing blood at a health care provider's office or a commercial facility and sending the sample to a lab for analysis. A health care provider will test the blood sample to
- estimate how much blood the kidneys filter eachminute, called the estimated glomerular filtrationrate, or eGFR. The test results help the healthcare provider determine the amount of kidneydamage from hemolytic uremic syndrome. - check red blood cell and platelet levels. - check for liver and kidney function. - assess protein levels in the blood.
Stool Test
A stool test is the analysis of a sample of stool. The health care provider will give the child's parent or caretaker a container for catching and storing the stool. The parent or caretaker returns the sample to the health care provider or a commercial facility that will send the sample to a lab for analysis. Stool tests can show the presence of E. coli O157:H7.
Kidney Biopsy
Biopsy is a procedure that involves taking a small piece of kidney tissue for examination with a microscope. A health care provider performs the biopsy in an outpatient center or a hospital. The health care provider will give the child light sedation and local anesthetic; however, in some cases, the child will require general anesthesia. A pathologista doctor who specializes in diagnosing diseasesexamines the tissue in a lab. The pathologist looks for signs of kidney disease and infection. The test can help diagnose hemolytic uremic syndrome. |
What are the complications of Hemolytic Uremic Syndrome in Children ? | Most children who develop hemolytic uremic syndrome and its complications recover without permanent damage to their health.1
However, children with hemolytic uremic syndrome may have serious and sometimes life-threatening complications, including
- acute kidney injury - high blood pressure - blood-clotting problems that can lead to bleeding - seizures - heart problems - chronic, or long lasting, kidney disease - stroke - coma |
What are the treatments for Hemolytic Uremic Syndrome in Children ? | A health care provider will treat a child with hemolytic uremic syndrome by addressing
- urgent symptoms and preventing complications - acute kidney injury - chronic kidney disease (CKD)
In most cases, health care providers do not treat children with hemolytic uremic syndrome with antibiotics unless they have infections in other areas of the body. With proper management, most children recover without long-term health problems.2
Treating Urgent Symptoms and Preventing Complications
A health care provider will treat a child's urgent symptoms and try to prevent complications by
- observing the child closely in the hospital - replacing minerals, such as potassium and salt, and fluids through an intravenous (IV) tube - giving the child red blood cells and platelets cells in the blood that help with clottingthrough an IV - giving the child IV nutrition - treating high blood pressure with medications
Treating Acute Kidney Injury
If necessary, a health care provider will treat acute kidney injury with dialysisthe process of filtering wastes and extra fluid from the body with an artificial kidney. The two forms of dialysis are hemodialysis and peritoneal dialysis. Most children with acute kidney injury need dialysis for a short time only.
Treating Chronic Kidney Disease
Some children may sustain significant kidney damage that slowly develops into CKD. Children who develop CKD must receive treatment to replace the work the kidneys do. The two types of treatment are dialysis and transplantation.
In most cases, health care providers treat CKD with a kidney transplant. A kidney transplant is surgery to place a healthy kidney from someone who has just died or a living donor, most often a family member, into a person's body to take over the job of the failing kidney. Though some children receive a kidney transplant before their kidneys fail completely, many children begin with dialysis to stay healthy until they can have a transplant.
More information is provided in the NIDDK health topic, Treatment Methods for Kidney Failure in Children. |
How to prevent Hemolytic Uremic Syndrome in Children ? | Parents and caregivers can help prevent childhood hemolytic uremic syndrome due to E. coli O157:H7 by
- avoiding unclean swimming areas - avoiding unpasteurized milk, juice, and cider - cleaning utensils and food surfaces often - cooking meat to an internal temperature of at least 160 F - defrosting meat in the microwave or refrigerator - keeping children out of pools if they have had diarrhea - keeping raw foods separate - washing hands before eating - washing hands well after using the restroom and after changing diapers
When a child is taking medications that may cause hemolytic uremic syndrome, it is important that the parent or caretaker watch for symptoms and report any changes in the child's condition to the health care provider as soon as possible. |
What to do for Hemolytic Uremic Syndrome in Children ? | At the beginning of the illness, children with hemolytic uremic syndrome may need IV nutrition or supplements to help maintain fluid balance in the body. Some children may need to follow a low-salt diet to help prevent swelling and high blood pressure.
Health care providers will encourage children with hemolytic uremic syndrome to eat when they are hungry. Most children who completely recover and do not have permanent kidney damage can return to their usual diet. |

However, if a child becomes infected with the O157:H7 strain of E. coli, the bacteria will lodge in the digestive tract and produce toxins that can enter the bloodstream. - A child with hemolytic uremic syndrome may develop signs and symptoms similar to those seen with gastroenteritis, an inflammation of the lining of the stomach, small intestine, and large intestine. - Most children who develop hemolytic uremic syndrome and its complications recover without permanent damage to their health. - Some children may sustain significant kidney damage that slowly develops into chronic kidney disease (CKD). - Parents and caregivers can help prevent childhood hemolytic uremic syndrome due to E. coli O157:H7 by - avoiding unclean swimming areas - avoiding unpasteurized milk, juice, and cider - cleaning utensils and food surfaces often - cooking meat to an internal temperature of at least 160 F - defrosting meat in the microwave or refrigerator - keeping children out of pools if they have had diarrhea - keeping raw foods separate - washing hands before eating - washing hands well after using the restroom and after changing diapers |
What is (are) Celiac Disease ? | Celiac disease is an immune disorder in which people cannot tolerate gluten because it damages the inner lining of their small intestine and prevents it from absorbing nutrients. The small intestine is the tubeshaped organ between the stomach and large intestine. Gluten is a protein found in wheat, rye, and barley and occasionally in some products such as vitamin and nutrient supplements, lip balms, and certain medications.
The immune system is the body's natural defense system and normally protects the body from infection. However, when a person has celiac disease, gluten causes the immune system to react in a way that can cause intestinal inflammationirritation or swellingand long-lasting damage.
When people with celiac disease eat foods or use products containing gluten, their immune system responds by damaging or destroying villithe tiny, fingerlike projections on the inner lining of the small intestine. Villi normally absorb nutrients from food and pass the nutrients through the walls of the small intestine and into the bloodstream. Without healthy villi, people can become malnourished, no matter how much food they eat. |
What causes Celiac Disease ? | Researchers do not know the exact cause of celiac disease. Celiac disease sometimes runs in families. In 50 percent of people who have celiac disease, a family member, when screened, also has the disease.1
A person's chances of developing celiac disease increase when his or her genestraits passed from parent to childhave variants, or changes. In celiac disease, certain gene variants and other factors, such as a person's exposure to things in his or her environment, can lead to celiac disease. Read more about genes and genetic conditions at www.ghr.nlm.nih.gov.
For most people, eating something with gluten is harmless. For others, an exposure to gluten can cause, or trigger, celiac disease to become active. Sometimes surgery, pregnancy, childbirth, a viral infection, or severe emotional stress can also trigger celiac disease symptoms. |
How many people are affected by Celiac Disease ? | As many as one in 141 Americans has celiac disease, although most remain undiagnosed.2 Celiac disease affects children and adults in all parts of the world and is more common in Caucasians and females.
Celiac disease is also more common among people with certain genetic diseases, including Down syndrome and Turner syndromea condition that affects girls' development. |
What are the symptoms of Celiac Disease ? | A person may experience digestive signs and symptoms, or symptoms in other parts of the body. Digestive signs and symptoms are more common in children and can include
- abdominal bloating - chronic diarrhea - constipation - gas - pale, foul-smelling, or fatty stool - stomach pain - nausea - vomiting
Being unable to absorb nutrients during the years when nutrition is critical to a child's normal growth and development can lead to other health problems, such as
- failure to thrive in infants - slowed growth and short stature - weight loss - irritability or change in mood - delayed puberty - dental enamel defects of permanent teeth
Adults are less likely to have digestive signs and symptoms and may instead have one or more of the following:
- anemia - bone or joint pain - canker sores inside the mouth - depression or anxiety - dermatitis herpetiformis, an itchy, blistering skin rash - fatigue, or feeling tired - infertility or recurrent miscarriage - missed menstrual periods - seizures - tingling numbness in the hands and feet - weak and brittle bones, or osteoporosis - headaches
Intestinal inflammation can cause other symptoms, such as
- feeling tired for long periods of time - abdominal pain and bloating - ulcers - blockages in the intestine
Celiac disease can produce an autoimmune reaction, or a self-directed immune reaction, in which a person's immune system attacks healthy cells in the body. This reaction can spread outside of the gastrointestinal tract to affect other areas of the body, including the
- spleen - skin - nervous system - bones - joints
Recognizing celiac disease can be difficult because some of its symptoms are similar to those of other diseases and conditions. Celiac disease can be confused with
- irritable bowel syndrome (IBS) - iron-deficiency anemia caused by menstrual blood loss - lactose intolerance - inflammatory bowel disease - diverticulitis - intestinal infections - chronic fatigue syndrome
As a result, celiac disease has long been underdiagnosed or misdiagnosed. As health care providers become more aware of the many varied symptoms of the disease and reliable blood tests become more available, diagnosis rates are increasing, particularly for adults.
Dermatitis Herpetiformis Dermatitis herpetiformis is a chronic, itchy, blistering skin rashusually on the elbows, knees, buttocks, back, or scalpthat affects about 5 to 10 percent of people with celiac disease.3 Men with dermatitis herpetiformis may also have oral or genital lesions. People with dermatitis herpetiformis may have no other signs or symptoms of celiac disease. Skin deposits of antibodiesproteins that react against the body's own cells or tissuescommon in celiac disease cause dermatitis herpetiformis. Ingesting gluten triggers these antibodies. More information is provided in the NIDDK health topic, Dermatitis Herpetiformis: Skin Manifestation of Celiac Disease. |
What are the symptoms of Celiac Disease ? | Signs and symptoms of celiac disease vary from person to person because of numerous factors, including
- the length of time a person was breastfed as an infant; some studies have shown that the longer an infant was breastfed, the later the symptoms of celiac disease appear - the age a person started eating gluten - the amount of gluten a person eats - agesymptoms can vary between young children and adults - the degree of damage to the small intestine
Some people with celiac disease have no signs or symptoms; however, they can still develop complications of the disease over time. Long-term complications include
- malnutrition - liver diseases - intestinal cancer - lymphoma |
How to diagnose Celiac Disease ? | A health care provider diagnoses celiac disease with
- a medical and family history - a physical exam - blood tests - an intestinal biopsy - a skin biopsy
Medical and Family History
Taking a medical and family history may help a health care provider diagnose celiac disease. He or she will ask the patient or caregiver to provide a medical and family history, specifically if anyone in the patient's family has a history of celiac disease.
Physical Exam
A physical exam may help diagnose celiac disease. During a physical exam, a health care provider usually
- examines the patient's body for malnutrition or a rash - uses a stethoscope to listen to sounds within the abdomen - taps on the patient's abdomen checking for bloating and pain
Blood Tests
A blood test involves drawing blood at a health care provider's office or a commercial facility and sending the sample to a lab for analysis. A blood test can show the presence of antibodies that are common in celiac disease.
If blood test results are negative and a health care provider still suspects celiac disease, he or she may order additional blood tests, which can affect test results.
Before the blood tests, patients should continue to eat a diet that includes foods with gluten, such as breads and pastas. If a patient stops eating foods with gluten before being tested, the results may be negative for celiac disease even if the disease is present.
Intestinal Biopsy
If blood tests suggest that a patient has celiac disease, a health care provider will perform a biopsy of the patient's small intestine to confirm the diagnosis. A biopsy is a procedure that involves taking a piece of tissue for examination with a microscope. A health care provider performs the biopsy in an outpatient center or a hospital. He or she will give the patient light sedation and a local anesthetic. Some patients may receive general anesthesia.
During the biopsy, a health care provider removes tiny pieces of tissue from the patient's small intestine using an endoscopea small, flexible camera with a light. The health care provider carefully feeds the endoscope down the patient's esophagus and into the stomach and small intestine. A small camera mounted on the endoscope transmits a video image to a monitor, allowing close examination of the intestinal lining. The health care provider then takes the samples using tiny tools that he or she passes through the endoscope. A pathologista doctor who specializes in examining tissues to diagnose diseasesexamines the tissue in a lab. The test can show damage to the villi in the small intestine.
Skin Biopsy
When a health care provider suspects that a patient has dermatitis herpetiformis, he or she will perform a skin biopsy. A skin biopsy is a procedure that involves removing tiny pieces of skin tissue for examination with a microscope. A health care provider performs the biopsy in an outpatient center or a hospital. The patient receives a local anesthetic; however, in some cases, the patient will require general anesthesia.
A pathologist examines the skin tissue in a lab and checks the tissue for antibodies that are common in celiac disease. If the skin tissue tests positive for the antibodies, a health care provider will perform blood tests to confirm celiac disease. If the skin biopsy and blood tests both suggest celiac disease, the patient may not need an intestinal biopsy for diagnosis.
Genetic Tests In some cases, a health care provider will order genetic blood tests to confirm or rule out a diagnosis of celiac disease. Most people with celiac disease have gene pairs that contain at least one of the human leukocyte antigen (HLA) gene variants.4 However, these variants are also common in people without celiac disease, so their presence alone cannot diagnose celiac disease. If a biopsy and other blood tests do not give a clear diagnosis of celiac disease, a health care provider may test a patient for HLA gene variants. If the gene variants are not present, celiac disease is unlikely. |

What are the treatments for Celiac Disease ? | Most people with celiac disease have a significant improvement in symptoms when they follow a gluten-free diet. Health care providers typically refer people to a dietitian who specializes in treating people with the disease. The dietitian will teach the person to avoid gluten while following a healthy and nutritious diet. The dietitian will give the person instructions for how to
- read food and product labels and identify ingredients that contain gluten - make healthy choices about the types of foods to eat - design everyday meal plans
For most people, following a gluten-free diet will stop symptoms, heal existing intestinal damage, and prevent further damage. Symptoms may improve within days to weeks of starting the diet. The small intestine usually heals in 3 to 6 months in children. Complete healing can take several years in adults. Once the intestine heals, the villi will absorb nutrients from food into the bloodstream normally.
Some people with celiac disease show no improvement after starting a gluten-free diet. The most common reason for poor response to dietary changes is that people are still consuming small amounts of gluten, which can damage the small intestineeven in people without symptoms. Most people start responding to the gluten-free diet once they find and eliminate hidden sources of gluten from their diet. Hidden sources of gluten include additives made with wheat, such as
- modified food starch - preservatives - stabilizers
Did you know that medications and nonfood products may contain gluten? Medications, supplements, and other products may also contain lecithin, a hidden source of gluten. People with celiac disease should ask a pharmacist about the ingredients in - prescription and over-the-counter medications - vitamins and mineral supplements - herbal and nutritional supplements Other products can be ingested or transferred from a person's hands to his or her mouth. Reading product labels can help people avoid gluten exposure. If a product's label does not list its ingredients, the manufacturer should provide a list upon request. Products that can contain gluten include - lipstick, lip gloss, and lip balm - cosmetics - skin and hair products - toothpaste and mouthwash - glue on stamps and envelopes - children's modeling dough, such as Play-Doh
Some people who continue to have symptoms even after changing their diet may have other conditions or disorders that are more common in people with celiac disease. These conditions may include
- small intestinal bacterial overgrowth, which happens when too many bacteria grow in the small intestine - pancreatic exocrine insufficiency, in which the pancreas does not produce enough digestive juice - microscopic colitis, an inflammation of the colon that a health care provider can see only with a microscope - IBS - lactose intolerance, a condition in which people have symptoms after consuming milk or milk products - other food intolerances, which may occur because of continued damage to the intestine
In some cases, people continue to have difficulty absorbing nutrients despite following a strict gluten-free diet. People with this condition, known as refractory celiac disease, have severely damaged intestines that cannot heal. Their intestines are not absorbing enough nutrients, so they may need to receive nutrients intravenously. Researchers continue to evaluate medications to treat refractory celiac disease.
Depending on a person's age at diagnosis, some complications of celiac disease will not improve, such as short stature and dental enamel defects.
For people with dermatitis herpetiformis, skin symptoms generally respond to a gluten-free diet and may recur if a person adds gluten back into his or her diet. Medications such as dapsone can control the rash's symptoms. Dapsone does not treat intestinal symptoms or damage, so people with dermatitis herpetiformis should maintain a gluten-free diet, even if they don't have digestive symptoms. Even when a person follows a gluten-free diet, the skin lesions from dermatitis herpetiformis may take months or even years to fully heal and often recur over the years. |
What to do for Celiac Disease ? | Eating, diet, and nutrition play a significant role in treating celiac disease. People with the disease should maintain a gluten-free diet by avoiding products that contain gluten. In other words, a person with celiac disease should not eat most grains, pasta, and cereal, and many processed foods.
People with celiac disease can eat a wellbalanced diet with a variety of foods. They can use potato, rice, soy, amaranth, quinoa, buckwheat, or bean flour instead of wheat flour. They can buy gluten-free bread, pasta, and other products from stores, or order products from special food companies. Meanwhile, "plain"meaning no additives or seasoningsmeat, fish, rice, fruits, and vegetables do not contain gluten, so people with celiac disease can eat these foods.
In the past, health care providers and dietitians advised people with celiac disease to avoid eating oats. Evidence suggests that most people with the disease can safely eat small amounts of oats, as long as the oats are not contaminated with wheat gluten during processing. People with celiac disease should talk with their health care team when deciding whether to include oats in their diet.
Eating out and shopping can be a challenge. Newly diagnosed people and their families may find support groups helpful as they adjust to a new approach to eating. People with celiac disease should
- read food labelsespecially canned, frozen, and processed foodsfor ingredients that contain gluten - avoid ingredients such as hydrolyzed vegetable protein, also called lecithin or soy lecithin - ask restaurant servers and chefs about ingredients and food preparation inquire whether a gluten-free menu is available - ask a dinner or party host about glutenfree options before attending a social gathering
Foods that are packaged as gluten-free tend to cost more than the same foods containing gluten. People following a gluten-free diet may find that naturally gluten-free foods are less expensive. With practice, looking for gluten can become second nature.
The Gluten-free Diet: Some Examples
The Academy of Nutrition and Dietetics has published recommendations for a glutenfree diet. The following chart illustrates these recommendations. This list is not complete, so people with celiac disease should discuss gluten-free food choices with a dietitian or health care professional who specializes in celiac disease. People with celiac disease should always read food ingredient lists carefully to make sure the food does not contain gluten.

Food Labeling Requirements On August 2, 2013, the U.S. Food and Drug Administration (FDA) published a new regulation defining the term "glutenfree" for voluntary food labeling. This new federal definition standardizes the meaning of "gluten-free" foods regulated by the FDA. Foods regulated by the U.S. Department of Agriculture, including meat and egg products, are not subject to this regulation. The regulation requires that any food with the term "gluten-free" on the label must meet all of the requirements of the definition, including that the food should contain fewer than 20 parts per million of gluten. The FDA rule also requires foods with the claims "no gluten," "free of gluten," and "without gluten" to meet the definition for "gluten-free." If a food that is labeled "gluten-free" includes "wheat" on the ingredients list or "contains wheat" after the list, the following statement must be included on the label: "The wheat has been processed to allow this food to meet the Food and Drug Administration requirements for gluten-free food." If this statement is included, people with celiac disease may consume foods labeled "gluten-free." |

What is (are) Proctitis ? | Proctitis is inflammation of the lining of the rectum, the lower end of the large intestine leading to the anus. The large intestine and anus are part of the gastrointestinal (GI) tract. The GI tract is a series of hollow organs joined in a long, twisting tube from the mouth to the anus. The movement of muscles in the GI tract, along with the release of hormones and enzymes, allows for the digestion of food. With proctitis, inflammation of the rectal liningcalled the rectal mucosais uncomfortable and sometimes painful. The condition may lead to bleeding or mucous discharge from the rectum, among other symptoms. |

What causes Proctitis ? | Proctitis has many causes, including acute, or sudden and short-term, and chronic, or long-lasting, conditions. Among the causes are the following:
- Sexually transmitted diseases (STDs). STDs that can be passed when a person is receiving anal sex are a common cause of proctitis. Common STD infections that can cause proctitis include gonorrhea, chlamydia, syphilis, and herpes. Herpes-induced proctitis may be particularly severe in people who are also infected with the HIV virus. - Non-STD infections. Infections that are not sexually transmitted also can cause proctitis. Salmonella and Shigella are examples of foodborne bacteria that can cause proctitis. Streptococcal proctitis sometimes occurs in children who have strep throat. - Anorectal trauma. Proctitis can be caused by trauma to the anorectal areawhich includes the rectum and anusfrom anal sex or the insertion of objects or harmful substances into the rectum, including the chemicals in some enemas. - Ulcerative colitis and Crohns disease. Two forms of inflammatory bowel disease (IBD)ulcerative colitis and Crohns diseasecan cause proctitis. Ulcerative colitis causes irritation and ulcers, also called sores, in the inner lining of the colonpart of the large intestineand rectum. Crohns disease usually causes irritation in the lower small intestinealso called the ileumor the colon, but it can affect any part of the GI tract. - Radiation therapy. People who have had radiation therapy that targets the pelvic area also may develop proctitis. Examples of those at risk are people with rectal, ovarian, or prostate cancer who have received radiation treatment directed to those areas. Symptoms of radiation proctitis, most commonly rectal bleeding, will typically occur within 6 weeks after beginning radiation therapy or more than 9 months after its completion. - Antibiotics. Use of antibiotics may be associated with proctitis in some people. While meant to kill infectioncausing bacteria, antibiotics can also kill nonharmful, or commensal, bacteria in the GI tract. The loss of commensal bacteria can then allow other harmful bacteria known as Clostridium difficile to cause an infection in the colon and rectum. |

What are the symptoms of Proctitis ? | Tenesmusan uncomfortable and frequent urge to have a bowel movementis one of the most common symptoms of proctitis. Other symptoms may include
- bloody bowel movements - rectal bleeding - a feeling of rectal fullness - anal or rectal pain - crampy abdominal pain - rectal discharge of mucus or pus - diarrhea or frequent passage of loose or liquid stools |
How to diagnose Proctitis ? | To diagnose proctitis, a health care provider will take a complete medical history and do a physical exam. The health care provider will ask the patient about symptoms, current and past medical conditions, family history, and sexual behavior that increases the risk of STD-induced proctitis. The physical exam will include an assessment of the patients vital signs, an abdominal exam, and a rectal exam.
Based on the patients physical exam, symptoms, and other medical information, the doctor will decide which lab tests and diagnostic tests are needed. Lab tests may include blood tests such as a complete blood count to evaluate for blood loss or infection, stool tests to isolate and identify bacteria that may cause disease, and an STD screening. The doctor also may use one of the following diagnostic tests:
- Rectal culture. A cotton swab is inserted into the rectum to obtain a sample that can be used in tests that isolate and identify organisms that may cause disease. - Anoscopy. This test allows examination of the anal canal and lower rectum by opening the anus using a special instrument called an anoscope. - Flexible sigmoidoscopy and colonoscopy. These tests are used to help diagnose Crohns disease. The tests are similar, but colonoscopy is used to view the entire colon and rectum, while flexible sigmoidoscopy is used to view just the lower colon and rectum. For both tests, a health care provider will provide written bowel prep instructions to follow at home before the test. The person may be asked to follow a clear liquid diet for 1 to 3 days before the test. A laxative may be required the night before the test. One or more enemas may be required the night before and about 2 hours before the test. |
What are the treatments for Proctitis ? | Treatment of proctitis depends on its cause. The goal of treatment is to reduce inflammation, control symptoms, and eliminate infection, if it is present. Only a doctor can determine the cause of proctitis and the best course of treatment. With proper medical attention, proctitis can be successfully treated.
Proctitis from Infection
If lab tests confirm that an STD or non-STD infection is present, medication is prescribed based on the type of infection found. Antibiotics are prescribed to kill bacteria; antiviral medications are prescribed to treat viruses. Although some STD viruses cannot be eliminated, antivirals can control their symptoms.
Proctitis from Other Causes
If antibiotic use triggered proctitis, the doctor may prescribe a different antibiotic designed to destroy the harmful bacteria that have developed in the intestines.
If proctitis is caused by anorectal trauma, the activity causing the inflammation should be stopped. Healing usually occurs in 4 to 6 weeks. The doctor may recommend over-the-counter medications such as antidiarrheals and those used for pain relief, such as aspirin and ibuprofen.
Treatment of radiation proctitis is based on symptoms. Radiation proctitis causing only mild symptoms such as occasional bleeding or tenesmus may heal without treatment. For people with persistent or severe bleeding, thermal therapy may be used to stop bleeding and inflammation. Thermal therapy is done during flexible sigmoidoscopy or colonoscopy and targets the rectal lining with a heat probe, electric current, or laser. Argon plasma coagulation is the most common thermal therapy used to control bleeding in radiation proctitis. In many cases, several treatments are required. Obstruction that results from a stricturea narrowing of the rectumcaused by radiation proctitis may be treated with stool softeners in mild cases. In people with narrower strictures, dilation to enlarge the narrow area may be required. Sucralfate, 5-aminosalicylic acidknown as 5-ASAor corticosteroid enemas can also be used to ease pain and reduce inflammation from radiation proctitis, although their effectiveness is limited.
When a chronic IBD such as ulcerative colitis or Crohns disease causes proctitis, treatment aims to reduce inflammation, control symptoms, and induce and maintain remissiona period when the person is symptom-free. Treatment depends on the extent and severity of the disease.
Anti-inflammation medications. Mild proctitis can often be effectively treated with topical mesalamine, either suppositories or enemas.
Some people with IBD and proctitis cannot tolerateor may have an incomplete response torectal therapy with 5-ASA suppositories or enemas. For these people, the doctor may prescribe oral medications alone or in combination with rectal therapy. Oral medications commonly used for proctitis contain salicylate. These include sulfasalazine- or mesalamine-containing medications, such as Asacol, Dipentum, or Pentasa. Possible side effects of oral administration of sulfasalazine- or mesalaminecontaining medications include nausea, vomiting, heartburn, diarrhea, and headache. Improvement in symptoms, including a decrease in bleeding, can occur within a few days, although complete healing requires 4 to 6 weeks of therapy.
Cortisone or steroids. These medications, also called corticosteroids, are effective at reducing inflammation. Prednisone and budesonide are generic names of two medications in this group. Corticosteroids for proctitis may be taken in pill, suppository, or enema form. When symptoms are at their worst, corticosteroids are usually prescribed in a large dose. The dosage is then gradually lowered once symptoms are controlled. Corticosteroids can cause serious side effects, including greater susceptibility to infection and osteoporosis, or weakening of the bones.
Immune system suppressors. Medications that suppress the immune systemcalled immunosuppressive medicationsare also used to treat proctitis. The most commonly prescribed medication is 6-mercaptopurine or a related medication, azathioprine. Immunosuppressive medications work by blocking the immune reaction that contributes to inflammation. These medications may cause side effects such as nausea, vomiting, and diarrhea and may lower a persons resistance to infection. Some patients are treated with a combination of corticosteroids and immunosuppressive medications. Some studies suggest that immunosuppressive medications may enhance the effectiveness of corticosteroids.
Infliximab (Remicade). Researchers have found that high levels of a protein produced by the immune system, called tumor necrosis factor (TNF), are present in people with Crohns disease. Infliximab is the first of a group of medications that bind to TNF substances to block the bodys inflammation response. The U.S. Food and Drug Administration approved the medication for the treatment of moderate to severe Crohns disease that does not respond to standard therapiesmesalamine substances, corticosteroids, immunosuppressive medicationsand for the treatment of open, draining fistulas. The medication is also given to people who have Crohns disease with proctitis. Some studies suggest that infliximab may enhance the effectiveness of immunosuppressive medications.
Bacterial infection can occur with flare-ups of ulcerative colitis or Crohns disease. Antibiotics may also be used to treat flare-ups in people with IBD and proctitis.
More information about the treatment of IBD is provided in the NIDDK health topics, Ulcerative Colitis and Crohns Disease. |
What to do for Proctitis ? | Drinking plenty of fluids is important when diarrhea or frequent passage of loose or liquid stools occurs.
Avoiding caffeine and foods that are greasy, high in fiber, or sweet may lessen diarrhea symptoms. Some people also have problems digesting lactosethe sugar found in milk and milk productsduring or after a bout of diarrhea. Yogurt, which has less lactose than milk, is often better tolerated. Yogurt with active, live bacterial cultures may even help people recover from diarrhea more quickly.
If diarrhea symptoms improve, soft, bland foods can be added to the diet, including bananas, plain rice, boiled potatoes, toast, crackers, cooked carrots, and baked chicken without the skin or fat. If the diarrhea stops, a normal diet may be resumed if tolerated. |
What are the treatments for Proctitis ? | Proctitis that is not treated or does not respond to treatment may lead to complications, including
- severe bleeding and anemiaa condition in which red blood cells are fewer or smaller than normal, which means less oxygen is carried to the bodys cells - abscessespainful, swollen, pus-filled areas caused by infection - ulcers on the intestinal lining - fistulasabnormal connections between two parts inside the body |
How to prevent Proctitis ? | People who receive anal sex can avoid getting STD-related proctitis by having their partner use a condom. If anorectal trauma caused proctitis, stopping the activity that triggered inflammation often will stop the inflammation and prevent recurrence.
Other causes of proctitis cannot always be prevented. However, their symptoms can be treated by a doctor. |

What is (are) Causes of Diabetes ? | Diabetes is a complex group of diseases with a variety of causes. People with diabetes have high blood glucose, also called high blood sugar or hyperglycemia.
Diabetes is a disorder of metabolismthe way the body uses digested food for energy. The digestive tract breaks down carbohydratessugars and starches found in many foodsinto glucose, a form of sugar that enters the bloodstream. With the help of the hormone insulin, cells throughout the body absorb glucose and use it for energy. Diabetes develops when the body doesnt make enough insulin or is not able to use insulin effectively, or both.
Insulin is made in the pancreas, an organ located behind the stomach. The pancreas contains clusters of cells called islets. Beta cells within the islets make insulin and release it into the blood.
If beta cells dont produce enough insulin, or the body doesnt respond to the insulin that is present, glucose builds up in the blood instead of being absorbed by cells in the body, leading to prediabetes or diabetes. Prediabetes is a condition in which blood glucose levels or A1C levelswhich reflect average blood glucose levelsare higher than normal but not high enough to be diagnosed as diabetes. In diabetes, the bodys cells are starved of energy despite high blood glucose levels.
Over time, high blood glucose damages nerves and blood vessels, leading to complications such as heart disease, stroke, kidney disease, blindness, dental disease, and amputations. Other complications of diabetes may include increased susceptibility to other diseases, loss of mobility with aging, depression, and pregnancy problems. No one is certain what starts the processes that cause diabetes, but scientists believe genes and environmental factors interact to cause diabetes in most cases.
The two main types of diabetes are type 1 diabetes and type 2 diabetes. A third type, gestational diabetes, develops only during pregnancy. Other types of diabetes are caused by defects in specific genes, diseases of the pancreas, certain drugs or chemicals, infections, and other conditions. Some people show signs of both type 1 and type 2 diabetes. |
What causes Causes of Diabetes ? | Type 1 diabetes is caused by a lack of insulin due to the destruction of insulin-producing beta cells in the pancreas. In type 1 diabetesan autoimmune diseasethe bodys immune system attacks and destroys the beta cells. Normally, the immune system protects the body from infection by identifying and destroying bacteria, viruses, and other potentially harmful foreign substances. But in autoimmune diseases, the immune system attacks the bodys own cells. In type 1 diabetes, beta cell destruction may take place over several years, but symptoms of the disease usually develop over a short period of time.
Type 1 diabetes typically occurs in children and young adults, though it can appear at any age. In the past, type 1 diabetes was called juvenile diabetes or insulin-dependent diabetes mellitus.
Latent autoimmune diabetes in adults (LADA) may be a slowly developing kind of type 1 diabetes. Diagnosis usually occurs after age 30. In LADA, as in type 1 diabetes, the bodys immune system destroys the beta cells. At the time of diagnosis, people with LADA may still produce their own insulin, but eventually most will need insulin shots or an insulin pump to control blood glucose levels.
Genetic Susceptibility
Heredity plays an important part in determining who is likely to develop type 1 diabetes. Genes are passed down from biological parent to child. Genes carry instructions for making proteins that are needed for the bodys cells to function. Many genes, as well as interactions among genes, are thought to influence susceptibility to and protection from type 1 diabetes. The key genes may vary in different population groups. Variations in genes that affect more than 1 percent of a population group are called gene variants.
Certain gene variants that carry instructions for making proteins called human leukocyte antigens (HLAs) on white blood cells are linked to the risk of developing type 1 diabetes. The proteins produced by HLA genes help determine whether the immune system recognizes a cell as part of the body or as foreign material. Some combinations of HLA gene variants predict that a person will be at higher risk for type 1 diabetes, while other combinations are protective or have no effect on risk.
While HLA genes are the major risk genes for type 1 diabetes, many additional risk genes or gene regions have been found. Not only can these genes help identify people at risk for type 1 diabetes, but they also provide important clues to help scientists better understand how the disease develops and identify potential targets for therapy and prevention.
Genetic testing can show what types of HLA genes a person carries and can reveal other genes linked to diabetes. However, most genetic testing is done in a research setting and is not yet available to individuals. Scientists are studying how the results of genetic testing can be used to improve type 1 diabetes prevention or treatment.
Autoimmune Destruction of Beta Cells
In type 1 diabetes, white blood cells called T cells attack and destroy beta cells. The process begins well before diabetes symptoms appear and continues after diagnosis. Often, type 1 diabetes is not diagnosed until most beta cells have already been destroyed. At this point, a person needs daily insulin treatment to survive. Finding ways to modify or stop this autoimmune process and preserve beta cell function is a major focus of current scientific research.
Recent research suggests insulin itself may be a key trigger of the immune attack on beta cells. The immune systems of people who are susceptible to developing type 1 diabetes respond to insulin as if it were a foreign substance, or antigen. To combat antigens, the body makes proteins called antibodies. Antibodies to insulin and other proteins produced by beta cells are found in people with type 1 diabetes. Researchers test for these antibodies to help identify people at increased risk of developing the disease. Testing the types and levels of antibodies in the blood can help determine whether a person has type 1 diabetes, LADA, or another type of diabetes.
Environmental Factors
Environmental factors, such as foods, viruses, and toxins, may play a role in the development of type 1 diabetes, but the exact nature of their role has not been determined. Some theories suggest that environmental factors trigger the autoimmune destruction of beta cells in people with a genetic susceptibility to diabetes. Other theories suggest that environmental factors play an ongoing role in diabetes, even after diagnosis.
Viruses and infections. A virus cannot cause diabetes on its own, but people are sometimes diagnosed with type 1 diabetes during or after a viral infection, suggesting a link between the two. Also, the onset of type 1 diabetes occurs more frequently during the winter when viral infections are more common. Viruses possibly associated with type 1 diabetes include coxsackievirus B, cytomegalovirus, adenovirus, rubella, and mumps. Scientists have described several ways these viruses may damage or destroy beta cells or possibly trigger an autoimmune response in susceptible people. For example, anti-islet antibodies have been found in patients with congenital rubella syndrome, and cytomegalovirus has been associated with significant beta cell damage and acute pancreatitisinflammation of the pancreas. Scientists are trying to identify a virus that can cause type 1 diabetes so that a vaccine might be developed to prevent the disease.
Infant feeding practices. Some studies have suggested that dietary factors may raise or lower the risk of developing type 1 diabetes. For example, breastfed infants and infants receiving vitamin D supplements may have a reduced risk of developing type 1 diabetes, while early exposure to cows milk and cereal proteins may increase risk. More research is needed to clarify how infant nutrition affects the risk for type 1 diabetes.

What causes Causes of Diabetes ? | Type 2 diabetesthe most common form of diabetesis caused by a combination of factors, including insulin resistance, a condition in which the bodys muscle, fat, and liver cells do not use insulin effectively. Type 2 diabetes develops when the body can no longer produce enough insulin to compensate for the impaired ability to use insulin. Symptoms of type 2 diabetes may develop gradually and can be subtle; some people with type 2 diabetes remain undiagnosed for years.
Type 2 diabetes develops most often in middle-aged and older people who are also overweight or obese. The disease, once rare in youth, is becoming more common in overweight and obese children and adolescents. Scientists think genetic susceptibility and environmental factors are the most likely triggers of type 2 diabetes.
Genetic Susceptibility
Genes play a significant part in susceptibility to type 2 diabetes. Having certain genes or combinations of genes may increase or decrease a persons risk for developing the disease. The role of genes is suggested by the high rate of type 2 diabetes in families and identical twins and wide variations in diabetes prevalence by ethnicity. Type 2 diabetes occurs more frequently in African Americans, Alaska Natives, American Indians, Hispanics/Latinos, and some Asian Americans, Native Hawaiians, and Pacific Islander Americans than it does in non-Hispanic whites.
Recent studies have combined genetic data from large numbers of people, accelerating the pace of gene discovery. Though scientists have now identified many gene variants that increase susceptibility to type 2 diabetes, the majority have yet to be discovered. The known genes appear to affect insulin production rather than insulin resistance. Researchers are working to identify additional gene variants and to learn how they interact with one another and with environmental factors to cause diabetes.
Studies have shown that variants of the TCF7L2 gene increase susceptibility to type 2 diabetes. For people who inherit two copies of the variants, the risk of developing type 2 diabetes is about 80 percent higher than for those who do not carry the gene variant.1 However, even in those with the variant, diet and physical activity leading to weight loss help delay diabetes, according to the Diabetes Prevention Program (DPP), a major clinical trial involving people at high risk.
Genes can also increase the risk of diabetes by increasing a persons tendency to become overweight or obese. One theory, known as the thrifty gene hypothesis, suggests certain genes increase the efficiency of metabolism to extract energy from food and store the energy for later use. This survival trait was advantageous for populations whose food supplies were scarce or unpredictable and could help keep people alive during famine. In modern times, however, when high-calorie foods are plentiful, such a trait can promote obesity and type 2 diabetes.
Obesity and Physical Inactivity
Physical inactivity and obesity are strongly associated with the development of type 2 diabetes. People who are genetically susceptible to type 2 diabetes are more vulnerable when these risk factors are present.
An imbalance between caloric intake and physical activity can lead to obesity, which causes insulin resistance and is common in people with type 2 diabetes. Central obesity, in which a person has excess abdominal fat, is a major risk factor not only for insulin resistance and type 2 diabetes but also for heart and blood vessel disease, also called cardiovascular disease (CVD). This excess belly fat produces hormones and other substances that can cause harmful, chronic effects in the body such as damage to blood vessels.
The DPP and other studies show that millions of people can lower their risk for type 2 diabetes by making lifestyle changes and losing weight. The DPP proved that people with prediabetesat high risk of developing type 2 diabetescould sharply lower their risk by losing weight through regular physical activity and a diet low in fat and calories. In 2009, a follow-up study of DPP participantsthe Diabetes Prevention Program Outcomes Study (DPPOS)showed that the benefits of weight loss lasted for at least 10 years after the original study began.2
Read more about the DPP, funded under National Institutes of Health (NIH) clinical trial number NCT00004992, and the DPPOS, funded under NIH clinical trial number NCT00038727 in Diabetes Prevention Program.
Insulin Resistance
Insulin resistance is a common condition in people who are overweight or obese, have excess abdominal fat, and are not physically active. Muscle, fat, and liver cells stop responding properly to insulin, forcing the pancreas to compensate by producing extra insulin. As long as beta cells are able to produce enough insulin, blood glucose levels stay in the normal range. But when insulin production falters because of beta cell dysfunction, glucose levels rise, leading to prediabetes or diabetes.
Abnormal Glucose Production by the Liver
In some people with diabetes, an abnormal increase in glucose production by the liver also contributes to high blood glucose levels. Normally, the pancreas releases the hormone glucagon when blood glucose and insulin levels are low. Glucagon stimulates the liver to produce glucose and release it into the bloodstream. But when blood glucose and insulin levels are high after a meal, glucagon levels drop, and the liver stores excess glucose for later, when it is needed. For reasons not completely understood, in many people with diabetes, glucagon levels stay higher than needed. High glucagon levels cause the liver to produce unneeded glucose, which contributes to high blood glucose levels. Metformin, the most commonly used drug to treat type 2 diabetes, reduces glucose production by the liver.
The Roles of Insulin and Glucagon in Normal Blood Glucose Regulation
A healthy persons body keeps blood glucose levels in a normal range through several complex mechanisms. Insulin and glucagon, two hormones made in the pancreas, help regulate blood glucose levels:
- Insulin, made by beta cells, lowers elevated blood glucose levels. - Glucagon, made by alpha cells, raises low blood glucose levels.
- Insulin helps muscle, fat, and liver cells absorb glucose from the bloodstream, lowering blood glucose levels. - Insulin stimulates the liver and muscle tissue to store excess glucose. The stored form of glucose is called glycogen. - Insulin also lowers blood glucose levels by reducing glucose production in the liver.
- Glucagon signals the liver and muscle tissue to break down glycogen into glucose, which enters the bloodstream and raises blood glucose levels. - If the body needs more glucose, glucagon stimulates the liver to make glucose from amino acids.
Metabolic Syndrome
Metabolic syndrome, also called insulin resistance syndrome, refers to a group of conditions common in people with insulin resistance, including
- higher than normal blood glucose levels - increased waist size due to excess abdominal fat - high blood pressure - abnormal levels of cholesterol and triglycerides in the blood
Cell Signaling and Regulation
Cells communicate through a complex network of molecular signaling pathways. For example, on cell surfaces, insulin receptor molecules capture, or bind, insulin molecules circulating in the bloodstream. This interaction between insulin and its receptor prompts the biochemical signals that enable the cells to absorb glucose from the blood and use it for energy.
Problems in cell signaling systems can set off a chain reaction that leads to diabetes or other diseases. Many studies have focused on how insulin signals cells to communicate and regulate action. Researchers have identified proteins and pathways that transmit the insulin signal and have mapped interactions between insulin and body tissues, including the way insulin helps the liver control blood glucose levels. Researchers have also found that key signals also come from fat cells, which produce substances that cause inflammation and insulin resistance.
This work holds the key to combating insulin resistance and diabetes. As scientists learn more about cell signaling systems involved in glucose regulation, they will have more opportunities to develop effective treatments.
Beta Cell Dysfunction
Scientists think beta cell dysfunction is a key contributor to type 2 diabetes. Beta cell impairment can cause inadequate or abnormal patterns of insulin release. Also, beta cells may be damaged by high blood glucose itself, a condition called glucose toxicity.
Scientists have not determined the causes of beta cell dysfunction in most cases. Single gene defects lead to specific forms of diabetes called maturity-onset diabetes of the young (MODY). The genes involved regulate insulin production in the beta cells. Although these forms of diabetes are rare, they provide clues as to how beta cell function may be affected by key regulatory factors. Other gene variants are involved in determining the number and function of beta cells. But these variants account for only a small percentage of type 2 diabetes cases. Malnutrition early in life is also being investigated as a cause of beta cell dysfunction. The metabolic environment of the developing fetus may also create a predisposition for diabetes later in life.
Risk Factors for Type 2 Diabetes
People who develop type 2 diabetes are more likely to have the following characteristics:
- age 45 or older - overweight or obese - physically inactive - parent or sibling with diabetes - family background that is African American, Alaska Native, American Indian, Asian American, Hispanic/Latino, or Pacific Islander American - history of giving birth to a baby weighing more than 9 pounds - history of gestational diabetes - high blood pressure140/90 or aboveor being treated for high blood pressure - high-density lipoprotein (HDL), or good, cholesterol below 35 milligrams per deciliter (mg/dL), or a triglyceride level above 250 mg/dL - polycystic ovary syndrome, also called PCOS - prediabetesan A1C level of 5.7 to 6.4 percent; a fasting plasma glucose test result of 100125 mg/dL, called impaired fasting glucose; or a 2-hour oral glucose tolerance test result of 140199, called impaired glucose tolerance - acanthosis nigricans, a condition associated with insulin resistance, characterized by a dark, velvety rash around the neck or armpits - history of CVD
The American Diabetes Association (ADA) recommends that testing to detect prediabetes and type 2 diabetes be considered in adults who are overweight or obese and have one or more additional risk factors for diabetes. In adults without these risk factors, testing should begin at age 45. |
What causes Causes of Diabetes ? | Insulin Resistance and Beta Cell Dysfunction
Hormones produced by the placenta and other pregnancy-related factors contribute to insulin resistance, which occurs in all women during late pregnancy. Insulin resistance increases the amount of insulin needed to control blood glucose levels. If the pancreas cant produce enough insulin due to beta cell dysfunction, gestational diabetes occurs.
As with type 2 diabetes, excess weight is linked to gestational diabetes. Overweight or obese women are at particularly high risk for gestational diabetes because they start pregnancy with a higher need for insulin due to insulin resistance. Excessive weight gain during pregnancy may also increase risk.
Family History
Having a family history of diabetes is also a risk factor for gestational diabetes, suggesting that genes play a role in its development. Genetics may also explain why the disorder occurs more frequently in African Americans, American Indians, and Hispanics/Latinos. Many gene variants or combinations of variants may increase a womans risk for developing gestational diabetes. Studies have found several gene variants associated with gestational diabetes, but these variants account for only a small fraction of women with gestational diabetes.
Future Risk of Type 2 Diabetes
Because a womans hormones usually return to normal levels soon after giving birth, gestational diabetes disappears in most women after delivery. However, women who have gestational diabetes are more likely to develop gestational diabetes with future pregnancies and develop type 2 diabetes.3 Women with gestational diabetes should be tested for persistent diabetes 6 to 12 weeks after delivery and at least every 3 years thereafter.
Also, exposure to high glucose levels during gestation increases a childs risk for becoming overweight or obese and for developing type 2 diabetes later on. The result may be a cycle of diabetes affecting multiple generations in a family. For both mother and child, maintaining a healthy body weight and being physically active may help prevent type 2 diabetes. |
What causes Causes of Diabetes ? | Other types of diabetes have a variety of possible causes.
Genetic Mutations Affecting Beta Cells, Insulin, and Insulin Action
Some relatively uncommon forms of diabetes known as monogenic diabetes are caused by mutations, or changes, in a single gene. These mutations are usually inherited, but sometimes the gene mutation occurs spontaneously. Most of these gene mutations cause diabetes by reducing beta cells ability to produce insulin.
The most common types of monogenic diabetes are neonatal diabetes mellitus (NDM) and MODY. NDM occurs in the first 6 months of life. MODY is usually found during adolescence or early adulthood but sometimes is not diagnosed until later in life. More information about NDM and MODY is provided in the NIDDK health topic, Monogenic Forms of Diabetes.
Other rare genetic mutations can cause diabetes by damaging the quality of insulin the body produces or by causing abnormalities in insulin receptors.
Other Genetic Diseases
Diabetes occurs in people with Down syndrome, Klinefelter syndrome, and Turner syndrome at higher rates than the general population. Scientists are investigating whether genes that may predispose people to genetic syndromes also predispose them to diabetes.
The genetic disorders cystic fibrosis and hemochromatosis are linked to diabetes. Cystic fibrosis produces abnormally thick mucus, which blocks the pancreas. The risk of diabetes increases with age in people with cystic fibrosis. Hemochromatosis causes the body to store too much iron. If the disorder is not treated, iron can build up in and damage the pancreas and other organs.
Damage to or Removal of the Pancreas
Pancreatitis, cancer, and trauma can all harm the pancreatic beta cells or impair insulin production, thus causing diabetes. If the damaged pancreas is removed, diabetes will occur due to the loss of the beta cells.
Endocrine Diseases
Endocrine diseases affect organs that produce hormones. Cushings syndrome and acromegaly are examples of hormonal disorders that can cause prediabetes and diabetes by inducing insulin resistance. Cushings syndrome is marked by excessive production of cortisolsometimes called the stress hormone. Acromegaly occurs when the body produces too much growth hormone. Glucagonoma, a rare tumor of the pancreas, can also cause diabetes. The tumor causes the body to produce too much glucagon. Hyperthyroidism, a disorder that occurs when the thyroid gland produces too much thyroid hormone, can also cause elevated blood glucose levels.
Autoimmune Disorders
Rare disorders characterized by antibodies that disrupt insulin action can lead to diabetes. This kind of diabetes is often associated with other autoimmune disorders such as lupus erythematosus. Another rare autoimmune disorder called stiff-man syndrome is associated with antibodies that attack the beta cells, similar to type 1 diabetes.
Medications and Chemical Toxins
Some medications, such as nicotinic acid and certain types of diuretics, anti-seizure drugs, psychiatric drugs, and drugs to treat human immunodeficiency virus (HIV), can impair beta cells or disrupt insulin action. Pentamidine, a drug prescribed to treat a type of pneumonia, can increase the risk of pancreatitis, beta cell damage, and diabetes. Also, glucocorticoidssteroid hormones that are chemically similar to naturally produced cortisolmay impair insulin action. Glucocorticoids are used to treat inflammatory illnesses such as rheumatoid arthritis, asthma, lupus, and ulcerative colitis.
Many chemical toxins can damage or destroy beta cells in animals, but only a few have been linked to diabetes in humans. For example, dioxina contaminant of the herbicide Agent Orange, used during the Vietnam Warmay be linked to the development of type 2 diabetes. In 2000, based on a report from the Institute of Medicine, the U.S. Department of Veterans Affairs (VA) added diabetes to the list of conditions for which Vietnam veterans are eligible for disability compensation. Also, a chemical in a rat poison no longer in use has been shown to cause diabetes if ingested. Some studies suggest a high intake of nitrogen-containing chemicals such as nitrates and nitrites might increase the risk of diabetes. Arsenic has also been studied for possible links to diabetes.
Lipodystrophy
Lipodystrophy is a condition in which fat tissue is lost or redistributed in the body. The condition is associated with insulin resistance and type 2 diabetes. |

What is (are) Hyperthyroidism ? | Hyperthyroidism is a disorder that occurs when the thyroid gland makes more thyroid hormone than the body needs. Hyperthyroidism is sometimes called thyrotoxicosis, the technical term for too much thyroid hormone in the blood. Thyroid hormones circulate throughout the body in the bloodstream and act on virtually every tissue and cell in the body. Hyperthyroidism causes many of the bodys functions to speed up. About 1 percent of the U.S. population has hyperthyroidism.1 |
What is (are) Hyperthyroidism ? | The thyroid is a 2-inch-long, butterfly-shaped gland weighing less than 1 ounce. Located in the front of the neck below the larynx, or voice box, it has two lobes, one on each side of the windpipe. The thyroid is one of the glands that make up the endocrine system. The glands of the endocrine system produce, store, and release hormones into the bloodstream. The hormones then travel through the body and direct the activity of the bodys cells.
The thyroid gland makes two thyroid hormones, triiodothyronine (T3) and thyroxine (T4). T3 is made from T4 and is the more active hormone, directly affecting the tissues. Thyroid hormones affect metabolism, brain development, breathing, heart and nervous system functions, body temperature, muscle strength, skin dryness, menstrual cycles, weight, and cholesterol levels.
Thyroid hormone production is regulated by thyroid-stimulating hormone (TSH), which is made by the pituitary gland in the brain. When thyroid hormone levels in the blood are low, the pituitary releases more TSH. When thyroid hormone levels are high, the pituitary responds by decreasing TSH production. |
What causes Hyperthyroidism ? | Hyperthyroidism has several causes, including
- Graves disease - thyroid nodules - thyroiditis, or inflammation of the thyroid - consuming too much iodine - overmedicating with synthetic thyroid hormone, which is used to treat underactive thyroid
Rarely, hyperthyroidism is caused by a pituitary adenoma, which is a noncancerous tumor of the pituitary gland. In this case, hyperthyroidism is due to too much TSH.
Graves Disease
Graves disease, also known as toxic diffuse goiter, is the most common cause of hyperthyroidism in the United States. Graves disease is an autoimmune disorder. Normally, the immune system protects the body from infection by identifying and destroying bacteria, viruses, and other potentially harmful foreign substances. But in autoimmune diseases, the immune system attacks the bodys own cells and organs.
With Graves disease, the immune system makes an antibody called thyroid stimulating immunoglobulin (TSI) that attaches to thyroid cells. TSI mimics the action of TSH and stimulates the thyroid to make too much thyroid hormone.
More information is provided in the NIDDK health topic, Graves' disease.
Thyroid Nodules
Thyroid nodules, also called adenomas, are lumps in the thyroid. Thyroid nodules are common and usually noncancerous. About 3 to 7 percent of the U.S. population has them.2 However, nodules may become overactive and produce too much hormone.
A single overactive nodule is called a toxic adenoma. Multiple overactive nodules are called toxic multinodular goiter. Often found in older adults, toxic multinodular goiter can produce a large amount of excess thyroid hormone.
Thyroiditis
Thyroiditis is an inflammation of the thyroid that causes stored thyroid hormone to leak out of the thyroid gland. At first, the leakage raises hormone levels in the blood, leading to hyperthyroidism that lasts for 1 or 2 months. Most people then develop hypothyroidismwhen thyroid hormone levels are too lowbefore the thyroid is completely healed.
Several types of thyroiditis can cause hyperthyroidism followed by hypothyroidism:
- Subacute thyroiditis. This condition involves painful inflammation and enlargement of the thyroid. Experts are not sure what causes subacute thyroiditis, but it may be related to a viral or bacterial infection. The condition usually goes away on its own in a few months. - Postpartum thyroiditis. This type of thyroiditis develops after a woman gives birth. For more information, see the section titled What happens with pregnancy and thyroid conditions? - Silent thyroiditis. This type of thyroiditis is called silent because it is painless, as is postpartum thyroiditis, even though the thyroid may be enlarged. Like postpartum thyroiditis, silent thyroiditis is probably an autoimmune condition and sometimes develops into permanent hypothyroidism.
Consuming Too Much Iodine
The thyroid uses iodine to make thyroid hormone, so the amount of iodine consumed influences the amount of thyroid hormone the thyroid makes. In some people, consuming large amounts of iodine may cause the thyroid to make excess thyroid hormone.
Sometimes significant amounts of iodine are contained in medicationssuch as amiodarone, which is used to treat heart problemsor in supplements containing seaweed. Some cough syrups also contain large amounts of iodine. See Eating, Diet, and Nutrition for more information on iodine.
Overmedicating with Synthetic Thyroid Hormone
Some people who take synthetic thyroid hormone for hypothyroidism may take too much. People who take synthetic thyroid hormone should see their health care provider at least once a year to have their thyroid hormone levels checked and follow the health care providers instructions about the dosage.
Some other medications may also interact with synthetic thyroid hormone to raise hormone levels in the blood. People who take synthetic thyroid hormone should ask their health care provider about interactions when starting new medications. |
What are the symptoms of Hyperthyroidism ? | Hyperthyroidism has many symptoms that can vary from person to person. Some common symptoms of hyperthyroidism are
- nervousness or irritability - fatigue or muscle weakness - heat intolerance - trouble sleeping - hand tremors - rapid and irregular heartbeat - frequent bowel movements or diarrhea - weight loss - mood swings - goiter, which is an enlarged thyroid that may cause the neck to look swollen and can interfere with normal breathing and swallowing |
How to diagnose Hyperthyroidism ? | Many symptoms of hyperthyroidism are the same as those of other diseases, so hyperthyroidism usually cannot be diagnosed based on symptoms alone. With suspected hyperthyroidism, health care providers take a medical history and perform a thorough physical exam. Health care providers may then use several blood tests, such as the following, to confirm a diagnosis of hyperthyroidism and find its cause:
TSH test. The ultrasensitive TSH test is usually the first test a health care provider performs. This test detects even tiny amounts of TSH in the blood and is the most accurate measure of thyroid activity available. The TSH test is especially useful in detecting mild hyperthyroidism. Generally, a TSH reading below normal means a person has hyperthyroidism and a reading above normal means a person has hypothyroidism.
Health care providers may conduct additional tests to help confirm the diagnosis or determine the cause of hyperthyroidism.
T3 and T4 test. This test shows the levels of T3 and T4 in the blood. With hyperthyroidism, the levels of one or both of these hormones in the blood are higher than normal.
Thyroid-stimulating immunoglobulin (TSI) test. This test, also called a thyroidstimulating antibody test, measures the level of TSI in the blood. Most people with Graves disease have this antibody, but people whose hyperthyroidism is caused by other conditions do not.
Radioactive iodine uptake test. The radioactive iodine uptake test measures the amount of iodine the thyroid collects from the bloodstream. Measuring the amount of iodine in a persons thyroid helps the health care provider determine what is causing a persons hyperthyroidism. For example, low levels of iodine uptake might be a sign of thyroiditis, whereas high levels could indicate Graves disease.
Thyroid scan. A thyroid scan shows how and where iodine is distributed in the thyroid. The images of nodules and other possible irregularities help the health care provider diagnose the cause of a persons hyperthyroidism.
More information is provided in the NIDDK health topic, Thyroid Tests. |
What are the treatments for Hyperthyroidism ? | Health care providers treat hyperthyroidism with medications, radioiodine therapy, or thyroid surgery. The aim of treatment is to bring thyroid hormone levels to a normal state, thus preventing long-term complications, and to relieve uncomfortable symptoms. No single treatment works for everyone.
Treatment depends on the cause of hyperthyroidism and how severe it is. When choosing a treatment, health care providers consider a patients age, possible allergies to or side effects of the medications, other conditions such as pregnancy or heart disease, and the availability of an experienced thyroid surgeon.
Finding the right specialist for treatment is an important first step. Some professional societies, listed under For More Information, and endocrinology departments in local teaching hospitals can provide the names of local specialists.
Medications
Beta blockers. Health care providers may prescribe a medication called a beta blocker to reduce symptoms until other treatments take effect. Beta blockers act quickly to relieve many of the symptoms of hyperthyroidism, such as tremors, rapid heartbeat, and nervousness, but do not stop thyroid hormone production. Most people feel better within hours of taking these medications.
Antithyroid medications. Antithyroid therapy is the easiest way to treat hyperthyroidism. Antithyroid medications interfere with thyroid hormone production but dont usually have permanent results. Antithyroid medications are not used to treat thyroiditis.
Once treatment with antithyroid medications begins, thyroid hormone levels may not move into the normal range for several weeks or months. The average treatment time is about 1 to 2 years, but treatment can continue for many years.
Antithyroid medications can cause side effects in some people, including
- allergic reactions such as rashes and itching - a decrease in the number of white blood cells in the body, which can lower resistance to infection - liver failure, in rare cases
Stop your antithyroid medication and call your health care provider right away if you develop any of the following while taking antithyroid medications: - fatigue - weakness - vague abdominal pain - loss of appetite - skin rash or itching - easy bruising - yellowing of the skin or whites of the eyes, called jaundice - persistent sore throat - fever
In the United States, health care providers prescribe the antithyroid medication methimazole (Tapazole, Northyx) for most types of hyperthyroidism.
Antithyroid medications and pregnancy. Because pregnant and breastfeeding women cannot receive radioiodine therapy, they are usually treated with an antithyroid medication instead. However, experts agree that women in their first trimester of pregnancy should not take methimazole due to the rare occurrence of damage to the fetus. Another antithyroid medication, propylthiouracil (PTU), is available for women in this stage of pregnancy or for women who are allergic to or intolerant of methimazole and have no other treatment options.
Health care providers may prescribe PTU for the first trimester of pregnancy and switch to methimazole for the second and third trimesters. Some women are able to stop taking antithyroid medications in the last 4 to 8 weeks of pregnancy due to the remission of hyperthyroidism that occurs during pregnancy. However these women should continue to be monitored for recurrence of thyroid problems following delivery.
Studies have shown that mothers taking antithyroid medications may safely breastfeed. However, they should take only moderate doses, less than 1020 milligrams daily, of the antithyroid medication methimazole. Doses should be divided and taken after feedings, and the infants should be monitored for side effects.4
Women requiring higher doses of the antithyroid medication to control hyperthyroidism should not breastfeed.
Radioiodine Therapy
Radioactive iodine-131 is a common and effective treatment for hyperthyroidism. In radioiodine therapy, patients take radioactive iodine-131 by mouth. Because the thyroid gland collects iodine to make thyroid hormone, it will collect the radioactive iodine from the bloodstream in the same way. The radioactive iodine gradually destroys the cells that make up the thyroid gland but does not affect other body tissues.
More than one round of radioiodine therapy may be needed to bring thyroid hormone production into the normal range. In the meantime, treatment with beta blockers can control symptoms.
Almost everyone who receives radioactive iodine treatment eventually develops hypothyroidism. But health care providers consider this an acceptable outcome because hypothyroidism is easier to treat and has fewer long-term complications than hyperthyroidism. People who develop hypothyroidism must take synthetic thyroid hormone.
Radioiodine and pregnancy. Although iodine-131 is not known to cause birth defects or infertility, radioiodine therapy is not used in pregnant women or women who are breastfeeding. Radioactive iodine can be harmful to the fetus thyroid and can be passed from mother to child in breast milk. Experts recommend that women wait a year after treatment before becoming pregnant.
Thyroid Surgery
The least-used treatment is surgery to remove part or most of the thyroid gland. Sometimes surgery may be used to treat
- pregnant women who cannot tolerate antithyroid medications - people with large goiters - people who have cancerous thyroid nodules, though hyperthyroidism does not cause cancer
Before surgery, the health care provider may prescribe antithyroid medications to temporarily bring a patients thyroid hormone levels into the normal range. This presurgical treatment prevents a condition called thyroid storma sudden, severe worsening of symptomsthat can occur when hyperthyroid patients have general anesthesia.
When part of the thyroid is removedas a treatment for toxic nodules, for examplethyroid hormone levels may return to normal. But some surgical patients may still develop hypothyroidism and need to take synthetic thyroxine, a medication that is identical to the hormone, T4, made by the thyroid. If the entire thyroid is removed, lifelong thyroid hormone medication is necessary. After surgery, health care providers will continue to monitor patients thyroid hormone levels.
Although uncommon, certain problems can occur in thyroid surgery. The parathyroid glands can be damaged because they are located very close to the thyroid. These glands help control calcium and phosphorus levels in the body. Damage to the laryngeal nerve, also located close to the thyroid, can lead to voice changes or breathing problems. But when surgery is performed by an experienced surgeon, less than 1 percent of patients have permanent complications.5 People who need help finding a surgeon can contact one of the organizations listed under For More Information. |
What to do for Hyperthyroidism ? | Experts recommend that people eat a balanced diet to obtain most nutrients. More information about diet and nutrition is provided by the National Agricultural Library at www.nutrition.gov.
Dietary Supplements
Iodine is an essential mineral for the thyroid. However, people with autoimmune thyroid disease may be sensitive to harmful side effects from iodine. Taking iodine drops or eating foods containing large amounts of iodinesuch as seaweed, dulse, or kelpmay cause or worsen hyperthyroidism. More information about iodine is provided by the National Library of Medicine in the fact sheet, Iodine in diet, available at www.nlm.nih.gov/medlineplus.
Women need more iodine when they are pregnantabout 250 micrograms a daybecause the baby gets iodine from the mothers diet. In the United States, about 7 percent of pregnant women may not get enough iodine in their diet or through prenatal vitamins.6 Choosing iodized saltsalt supplemented with iodineover plain salt and prenatal vitamins containing iodine will ensure this need is met.
To help ensure coordinated and safe care, people should discuss their use of dietary supplements, such as iodine, with their health care provider. Tips for talking with health care providers are available through the National Center for Complementary and Integrative Health. |
What to do for Hyperthyroidism ? | - Hyperthyroidism is a disorder that occurs when the thyroid gland makes more thyroid hormone than the body needs. - Hyperthyroidism is most often caused by Graves disease, an autoimmune disorder. Other causes include thyroid nodules, thyroiditis, consuming too much iodine, and overmedicating with synthetic thyroid hormone. - Some symptoms of hyperthyroidism are nervousness or irritability, fatigue or muscle weakness, heat intolerance, trouble sleeping, hand tremors, rapid and irregular heartbeat, frequent bowel movements or diarrhea, weight loss, mood swings, and goiter. - Hyperthyroidism is much more common in women than men. - Hyperthyroidism is also more common in people older than age 60 and is often caused by thyroid nodules. Hyperthyroidism in this age group is sometimes misdiagnosed as depression or dementia. For people older than age 60, subclinical hyperthyroidism increases their chance of developing atrial fibrillation. - Women with hyperthyroidism should discuss their condition with their health care provider before becoming pregnant. - Hyperthyroidism is treated with medications, radioiodine therapy, or thyroid surgery. No single treatment works for everyone. |
What is (are) Causes of Diabetes ? | Diabetes is a complex group of diseases with a variety of causes. People with diabetes have high blood glucose, also called high blood sugar or hyperglycemia.
Diabetes is a disorder of metabolismthe way the body uses digested food for energy. The digestive tract breaks down carbohydratessugars and starches found in many foodsinto glucose, a form of sugar that enters the bloodstream. With the help of the hormone insulin, cells throughout the body absorb glucose and use it for energy. Diabetes develops when the body doesnt make enough insulin or is not able to use insulin effectively, or both.
Insulin is made in the pancreas, an organ located behind the stomach. The pancreas contains clusters of cells called islets. Beta cells within the islets make insulin and release it into the blood.
If beta cells dont produce enough insulin, or the body doesnt respond to the insulin that is present, glucose builds up in the blood instead of being absorbed by cells in the body, leading to prediabetes or diabetes. Prediabetes is a condition in which blood glucose levels or A1C levelswhich reflect average blood glucose levelsare higher than normal but not high enough to be diagnosed as diabetes. In diabetes, the bodys cells are starved of energy despite high blood glucose levels.
Over time, high blood glucose damages nerves and blood vessels, leading to complications such as heart disease, stroke, kidney disease, blindness, dental disease, and amputations. Other complications of diabetes may include increased susceptibility to other diseases, loss of mobility with aging, depression, and pregnancy problems. No one is certain what starts the processes that cause diabetes, but scientists believe genes and environmental factors interact to cause diabetes in most cases.
The two main types of diabetes are type 1 diabetes and type 2 diabetes. A third type, gestational diabetes, develops only during pregnancy. Other types of diabetes are caused by defects in specific genes, diseases of the pancreas, certain drugs or chemicals, infections, and other conditions. Some people show signs of both type 1 and type 2 diabetes. |
What causes Causes of Diabetes ? | Type 1 diabetes is caused by a lack of insulin due to the destruction of insulin-producing beta cells in the pancreas. In type 1 diabetesan autoimmune diseasethe bodys immune system attacks and destroys the beta cells. Normally, the immune system protects the body from infection by identifying and destroying bacteria, viruses, and other potentially harmful foreign substances. But in autoimmune diseases, the immune system attacks the bodys own cells. In type 1 diabetes, beta cell destruction may take place over several years, but symptoms of the disease usually develop over a short period of time.
Type 1 diabetes typically occurs in children and young adults, though it can appear at any age. In the past, type 1 diabetes was called juvenile diabetes or insulin-dependent diabetes mellitus.
Latent autoimmune diabetes in adults (LADA) may be a slowly developing kind of type 1 diabetes. Diagnosis usually occurs after age 30. In LADA, as in type 1 diabetes, the bodys immune system destroys the beta cells. At the time of diagnosis, people with LADA may still produce their own insulin, but eventually most will need insulin shots or an insulin pump to control blood glucose levels.
Genetic Susceptibility
Heredity plays an important part in determining who is likely to develop type 1 diabetes. Genes are passed down from biological parent to child. Genes carry instructions for making proteins that are needed for the bodys cells to function. Many genes, as well as interactions among genes, are thought to influence susceptibility to and protection from type 1 diabetes. The key genes may vary in different population groups. Variations in genes that affect more than 1 percent of a population group are called gene variants.
Certain gene variants that carry instructions for making proteins called human leukocyte antigens (HLAs) on white blood cells are linked to the risk of developing type 1 diabetes. The proteins produced by HLA genes help determine whether the immune system recognizes a cell as part of the body or as foreign material. Some combinations of HLA gene variants predict that a person will be at higher risk for type 1 diabetes, while other combinations are protective or have no effect on risk.
While HLA genes are the major risk genes for type 1 diabetes, many additional risk genes or gene regions have been found. Not only can these genes help identify people at risk for type 1 diabetes, but they also provide important clues to help scientists better understand how the disease develops and identify potential targets for therapy and prevention.
Genetic testing can show what types of HLA genes a person carries and can reveal other genes linked to diabetes. However, most genetic testing is done in a research setting and is not yet available to individuals. Scientists are studying how the results of genetic testing can be used to improve type 1 diabetes prevention or treatment.
Autoimmune Destruction of Beta Cells
In type 1 diabetes, white blood cells called T cells attack and destroy beta cells. The process begins well before diabetes symptoms appear and continues after diagnosis. Often, type 1 diabetes is not diagnosed until most beta cells have already been destroyed. At this point, a person needs daily insulin treatment to survive. Finding ways to modify or stop this autoimmune process and preserve beta cell function is a major focus of current scientific research.
Recent research suggests insulin itself may be a key trigger of the immune attack on beta cells. The immune systems of people who are susceptible to developing type 1 diabetes respond to insulin as if it were a foreign substance, or antigen. To combat antigens, the body makes proteins called antibodies. Antibodies to insulin and other proteins produced by beta cells are found in people with type 1 diabetes. Researchers test for these antibodies to help identify people at increased risk of developing the disease. Testing the types and levels of antibodies in the blood can help determine whether a person has type 1 diabetes, LADA, or another type of diabetes.
Environmental Factors
Environmental factors, such as foods, viruses, and toxins, may play a role in the development of type 1 diabetes, but the exact nature of their role has not been determined. Some theories suggest that environmental factors trigger the autoimmune destruction of beta cells in people with a genetic susceptibility to diabetes. Other theories suggest that environmental factors play an ongoing role in diabetes, even after diagnosis.
Viruses and infections. A virus cannot cause diabetes on its own, but people are sometimes diagnosed with type 1 diabetes during or after a viral infection, suggesting a link between the two. Also, the onset of type 1 diabetes occurs more frequently during the winter when viral infections are more common. Viruses possibly associated with type 1 diabetes include coxsackievirus B, cytomegalovirus, adenovirus, rubella, and mumps. Scientists have described several ways these viruses may damage or destroy beta cells or possibly trigger an autoimmune response in susceptible people. For example, anti-islet antibodies have been found in patients with congenital rubella syndrome, and cytomegalovirus has been associated with significant beta cell damage and acute pancreatitisinflammation of the pancreas. Scientists are trying to identify a virus that can cause type 1 diabetes so that a vaccine might be developed to prevent the disease.
Infant feeding practices. Some studies have suggested that dietary factors may raise or lower the risk of developing type 1 diabetes. For example, breastfed infants and infants receiving vitamin D supplements may have a reduced risk of developing type 1 diabetes, while early exposure to cows milk and cereal proteins may increase risk. More research is needed to clarify how infant nutrition affects the risk for type 1 diabetes.

What causes Causes of Diabetes ? | Type 2 diabetesthe most common form of diabetesis caused by a combination of factors, including insulin resistance, a condition in which the bodys muscle, fat, and liver cells do not use insulin effectively. Type 2 diabetes develops when the body can no longer produce enough insulin to compensate for the impaired ability to use insulin. Symptoms of type 2 diabetes may develop gradually and can be subtle; some people with type 2 diabetes remain undiagnosed for years.
Type 2 diabetes develops most often in middle-aged and older people who are also overweight or obese. The disease, once rare in youth, is becoming more common in overweight and obese children and adolescents. Scientists think genetic susceptibility and environmental factors are the most likely triggers of type 2 diabetes.
Genetic Susceptibility
Genes play a significant part in susceptibility to type 2 diabetes. Having certain genes or combinations of genes may increase or decrease a persons risk for developing the disease. The role of genes is suggested by the high rate of type 2 diabetes in families and identical twins and wide variations in diabetes prevalence by ethnicity. Type 2 diabetes occurs more frequently in African Americans, Alaska Natives, American Indians, Hispanics/Latinos, and some Asian Americans, Native Hawaiians, and Pacific Islander Americans than it does in non-Hispanic whites.
Recent studies have combined genetic data from large numbers of people, accelerating the pace of gene discovery. Though scientists have now identified many gene variants that increase susceptibility to type 2 diabetes, the majority have yet to be discovered. The known genes appear to affect insulin production rather than insulin resistance. Researchers are working to identify additional gene variants and to learn how they interact with one another and with environmental factors to cause diabetes.
Studies have shown that variants of the TCF7L2 gene increase susceptibility to type 2 diabetes. For people who inherit two copies of the variants, the risk of developing type 2 diabetes is about 80 percent higher than for those who do not carry the gene variant.1 However, even in those with the variant, diet and physical activity leading to weight loss help delay diabetes, according to the Diabetes Prevention Program (DPP), a major clinical trial involving people at high risk.
Genes can also increase the risk of diabetes by increasing a persons tendency to become overweight or obese. One theory, known as the thrifty gene hypothesis, suggests certain genes increase the efficiency of metabolism to extract energy from food and store the energy for later use. This survival trait was advantageous for populations whose food supplies were scarce or unpredictable and could help keep people alive during famine. In modern times, however, when high-calorie foods are plentiful, such a trait can promote obesity and type 2 diabetes.
Obesity and Physical Inactivity
Physical inactivity and obesity are strongly associated with the development of type 2 diabetes. People who are genetically susceptible to type 2 diabetes are more vulnerable when these risk factors are present.
An imbalance between caloric intake and physical activity can lead to obesity, which causes insulin resistance and is common in people with type 2 diabetes. Central obesity, in which a person has excess abdominal fat, is a major risk factor not only for insulin resistance and type 2 diabetes but also for heart and blood vessel disease, also called cardiovascular disease (CVD). This excess belly fat produces hormones and other substances that can cause harmful, chronic effects in the body such as damage to blood vessels.
The DPP and other studies show that millions of people can lower their risk for type 2 diabetes by making lifestyle changes and losing weight. The DPP proved that people with prediabetesat high risk of developing type 2 diabetescould sharply lower their risk by losing weight through regular physical activity and a diet low in fat and calories. In 2009, a follow-up study of DPP participantsthe Diabetes Prevention Program Outcomes Study (DPPOS)showed that the benefits of weight loss lasted for at least 10 years after the original study began.2
Read more about the DPP, funded under National Institutes of Health (NIH) clinical trial number NCT00004992, and the DPPOS, funded under NIH clinical trial number NCT00038727 in Diabetes Prevention Program.
Insulin Resistance
Insulin resistance is a common condition in people who are overweight or obese, have excess abdominal fat, and are not physically active. Muscle, fat, and liver cells stop responding properly to insulin, forcing the pancreas to compensate by producing extra insulin. As long as beta cells are able to produce enough insulin, blood glucose levels stay in the normal range. But when insulin production falters because of beta cell dysfunction, glucose levels rise, leading to prediabetes or diabetes.
Abnormal Glucose Production by the Liver
In some people with diabetes, an abnormal increase in glucose production by the liver also contributes to high blood glucose levels. Normally, the pancreas releases the hormone glucagon when blood glucose and insulin levels are low. Glucagon stimulates the liver to produce glucose and release it into the bloodstream. But when blood glucose and insulin levels are high after a meal, glucagon levels drop, and the liver stores excess glucose for later, when it is needed. For reasons not completely understood, in many people with diabetes, glucagon levels stay higher than needed. High glucagon levels cause the liver to produce unneeded glucose, which contributes to high blood glucose levels. Metformin, the most commonly used drug to treat type 2 diabetes, reduces glucose production by the liver.
The Roles of Insulin and Glucagon in Normal Blood Glucose Regulation
A healthy persons body keeps blood glucose levels in a normal range through several complex mechanisms. Insulin and glucagon, two hormones made in the pancreas, help regulate blood glucose levels:
- Insulin, made by beta cells, lowers elevated blood glucose levels. - Glucagon, made by alpha cells, raises low blood glucose levels.
- Insulin helps muscle, fat, and liver cells absorb glucose from the bloodstream, lowering blood glucose levels. - Insulin stimulates the liver and muscle tissue to store excess glucose. The stored form of glucose is called glycogen. - Insulin also lowers blood glucose levels by reducing glucose production in the liver.
- Glucagon signals the liver and muscle tissue to break down glycogen into glucose, which enters the bloodstream and raises blood glucose levels. - If the body needs more glucose, glucagon stimulates the liver to make glucose from amino acids.
Metabolic Syndrome
Metabolic syndrome, also called insulin resistance syndrome, refers to a group of conditions common in people with insulin resistance, including
- higher than normal blood glucose levels - increased waist size due to excess abdominal fat - high blood pressure - abnormal levels of cholesterol and triglycerides in the blood
Cell Signaling and Regulation
Cells communicate through a complex network of molecular signaling pathways. For example, on cell surfaces, insulin receptor molecules capture, or bind, insulin molecules circulating in the bloodstream. This interaction between insulin and its receptor prompts the biochemical signals that enable the cells to absorb glucose from the blood and use it for energy.
Problems in cell signaling systems can set off a chain reaction that leads to diabetes or other diseases. Many studies have focused on how insulin signals cells to communicate and regulate action. Researchers have identified proteins and pathways that transmit the insulin signal and have mapped interactions between insulin and body tissues, including the way insulin helps the liver control blood glucose levels. Researchers have also found that key signals also come from fat cells, which produce substances that cause inflammation and insulin resistance.
This work holds the key to combating insulin resistance and diabetes. As scientists learn more about cell signaling systems involved in glucose regulation, they will have more opportunities to develop effective treatments.
Beta Cell Dysfunction
Scientists think beta cell dysfunction is a key contributor to type 2 diabetes. Beta cell impairment can cause inadequate or abnormal patterns of insulin release. Also, beta cells may be damaged by high blood glucose itself, a condition called glucose toxicity.
Scientists have not determined the causes of beta cell dysfunction in most cases. Single gene defects lead to specific forms of diabetes called maturity-onset diabetes of the young (MODY). The genes involved regulate insulin production in the beta cells. Although these forms of diabetes are rare, they provide clues as to how beta cell function may be affected by key regulatory factors. Other gene variants are involved in determining the number and function of beta cells. But these variants account for only a small percentage of type 2 diabetes cases. Malnutrition early in life is also being investigated as a cause of beta cell dysfunction. The metabolic environment of the developing fetus may also create a predisposition for diabetes later in life.
Risk Factors for Type 2 Diabetes
People who develop type 2 diabetes are more likely to have the following characteristics:
- age 45 or older - overweight or obese - physically inactive - parent or sibling with diabetes - family background that is African American, Alaska Native, American Indian, Asian American, Hispanic/Latino, or Pacific Islander American - history of giving birth to a baby weighing more than 9 pounds - history of gestational diabetes - high blood pressure140/90 or aboveor being treated for high blood pressure - high-density lipoprotein (HDL), or good, cholesterol below 35 milligrams per deciliter (mg/dL), or a triglyceride level above 250 mg/dL - polycystic ovary syndrome, also called PCOS - prediabetesan A1C level of 5.7 to 6.4 percent; a fasting plasma glucose test result of 100125 mg/dL, called impaired fasting glucose; or a 2-hour oral glucose tolerance test result of 140199, called impaired glucose tolerance - acanthosis nigricans, a condition associated with insulin resistance, characterized by a dark, velvety rash around the neck or armpits - history of CVD
The American Diabetes Association (ADA) recommends that testing to detect prediabetes and type 2 diabetes be considered in adults who are overweight or obese and have one or more additional risk factors for diabetes. In adults without these risk factors, testing should begin at age 45. |
What causes Causes of Diabetes ? | Insulin Resistance and Beta Cell Dysfunction
Hormones produced by the placenta and other pregnancy-related factors contribute to insulin resistance, which occurs in all women during late pregnancy. Insulin resistance increases the amount of insulin needed to control blood glucose levels. If the pancreas cant produce enough insulin due to beta cell dysfunction, gestational diabetes occurs.
As with type 2 diabetes, excess weight is linked to gestational diabetes. Overweight or obese women are at particularly high risk for gestational diabetes because they start pregnancy with a higher need for insulin due to insulin resistance. Excessive weight gain during pregnancy may also increase risk.
Family History
Having a family history of diabetes is also a risk factor for gestational diabetes, suggesting that genes play a role in its development. Genetics may also explain why the disorder occurs more frequently in African Americans, American Indians, and Hispanics/Latinos. Many gene variants or combinations of variants may increase a womans risk for developing gestational diabetes. Studies have found several gene variants associated with gestational diabetes, but these variants account for only a small fraction of women with gestational diabetes.
Future Risk of Type 2 Diabetes
Because a womans hormones usually return to normal levels soon after giving birth, gestational diabetes disappears in most women after delivery. However, women who have gestational diabetes are more likely to develop gestational diabetes with future pregnancies and develop type 2 diabetes.3 Women with gestational diabetes should be tested for persistent diabetes 6 to 12 weeks after delivery and at least every 3 years thereafter.
Also, exposure to high glucose levels during gestation increases a childs risk for becoming overweight or obese and for developing type 2 diabetes later on. The result may be a cycle of diabetes affecting multiple generations in a family. For both mother and child, maintaining a healthy body weight and being physically active may help prevent type 2 diabetes. |
What causes Causes of Diabetes ? | Other types of diabetes have a variety of possible causes.
Genetic Mutations Affecting Beta Cells, Insulin, and Insulin Action
Some relatively uncommon forms of diabetes known as monogenic diabetes are caused by mutations, or changes, in a single gene. These mutations are usually inherited, but sometimes the gene mutation occurs spontaneously. Most of these gene mutations cause diabetes by reducing beta cells ability to produce insulin.
The most common types of monogenic diabetes are neonatal diabetes mellitus (NDM) and MODY. NDM occurs in the first 6 months of life. MODY is usually found during adolescence or early adulthood but sometimes is not diagnosed until later in life. More information about NDM and MODY is provided in the NIDDK health topic, Monogenic Forms of Diabetes.
Other rare genetic mutations can cause diabetes by damaging the quality of insulin the body produces or by causing abnormalities in insulin receptors.
Other Genetic Diseases
Diabetes occurs in people with Down syndrome, Klinefelter syndrome, and Turner syndrome at higher rates than the general population. Scientists are investigating whether genes that may predispose people to genetic syndromes also predispose them to diabetes.
The genetic disorders cystic fibrosis and hemochromatosis are linked to diabetes. Cystic fibrosis produces abnormally thick mucus, which blocks the pancreas. The risk of diabetes increases with age in people with cystic fibrosis. Hemochromatosis causes the body to store too much iron. If the disorder is not treated, iron can build up in and damage the pancreas and other organs.
Damage to or Removal of the Pancreas
Pancreatitis, cancer, and trauma can all harm the pancreatic beta cells or impair insulin production, thus causing diabetes. If the damaged pancreas is removed, diabetes will occur due to the loss of the beta cells.
Endocrine Diseases
Endocrine diseases affect organs that produce hormones. Cushings syndrome and acromegaly are examples of hormonal disorders that can cause prediabetes and diabetes by inducing insulin resistance. Cushings syndrome is marked by excessive production of cortisolsometimes called the stress hormone. Acromegaly occurs when the body produces too much growth hormone. Glucagonoma, a rare tumor of the pancreas, can also cause diabetes. The tumor causes the body to produce too much glucagon. Hyperthyroidism, a disorder that occurs when the thyroid gland produces too much thyroid hormone, can also cause elevated blood glucose levels.
Autoimmune Disorders
Rare disorders characterized by antibodies that disrupt insulin action can lead to diabetes. This kind of diabetes is often associated with other autoimmune disorders such as lupus erythematosus. Another rare autoimmune disorder called stiff-man syndrome is associated with antibodies that attack the beta cells, similar to type 1 diabetes.
Medications and Chemical Toxins
Some medications, such as nicotinic acid and certain types of diuretics, anti-seizure drugs, psychiatric drugs, and drugs to treat human immunodeficiency virus (HIV), can impair beta cells or disrupt insulin action. Pentamidine, a drug prescribed to treat a type of pneumonia, can increase the risk of pancreatitis, beta cell damage, and diabetes. Also, glucocorticoidssteroid hormones that are chemically similar to naturally produced cortisolmay impair insulin action. Glucocorticoids are used to treat inflammatory illnesses such as rheumatoid arthritis, asthma, lupus, and ulcerative colitis.
Many chemical toxins can damage or destroy beta cells in animals, but only a few have been linked to diabetes in humans. For example, dioxina contaminant of the herbicide Agent Orange, used during the Vietnam Warmay be linked to the development of type 2 diabetes. In 2000, based on a report from the Institute of Medicine, the U.S. Department of Veterans Affairs (VA) added diabetes to the list of conditions for which Vietnam veterans are eligible for disability compensation. Also, a chemical in a rat poison no longer in use has been shown to cause diabetes if ingested. Some studies suggest a high intake of nitrogen-containing chemicals such as nitrates and nitrites might increase the risk of diabetes. Arsenic has also been studied for possible links to diabetes.
Lipodystrophy
Lipodystrophy is a condition in which fat tissue is lost or redistributed in the body. The condition is associated with insulin resistance and type 2 diabetes. |

Medications and Chemical Toxins
Some medications, such as nicotinic acid and certain types of diuretics, anti-seizure drugs, psychiatric drugs, and drugs to treat human immunodeficiency virus (HIV), can impair beta cells or disrupt insulin action. Pentamidine, a drug prescribed to treat a type of pneumonia, can increase the risk of pancreatitis, beta cell damage, and diabetes. Also, glucocorticoidssteroid hormones that are chemically similar to naturally produced cortisolmay impair insulin action. Glucocorticoids are used to treat inflammatory illnesses such as rheumatoid arthritis, asthma, lupus, and ulcerative colitis.
Many chemical toxins can damage or destroy beta cells in animals, but only a few have been linked to diabetes in humans. For example, dioxina contaminant of the herbicide Agent Orange, used during the Vietnam Warmay be linked to the development of type 2 diabetes. In 2000, based on a report from the Institute of Medicine, the U.S. Department of Veterans Affairs (VA) added diabetes to the list of conditions for which Vietnam veterans are eligible for disability compensation. Also, a chemical in a rat poison no longer in use has been shown to cause diabetes if ingested. Some studies suggest a high intake of nitrogen-containing chemicals such as nitrates and nitrites might increase the risk of diabetes. Arsenic has also been studied for possible links to diabetes.
Lipodystrophy
Lipodystrophy is a condition in which fat tissue is lost or redistributed in the body. The condition is associated with insulin resistance and type 2 diabetes. |
What to do for Causes of Diabetes ? | - Diabetes is a complex group of diseases with a variety of causes. Scientists believe genes and environmental factors interact to cause diabetes in most cases. - People with diabetes have high blood glucose, also called high blood sugar or hyperglycemia. Diabetes develops when the body doesnt make enough insulin or is not able to use insulin effectively, or both. - Insulin is a hormone made by beta cells in the pancreas. Insulin helps cells throughout the body absorb and use glucose for energy. If the body does not produce enough insulin or cannot use insulin effectively, glucose builds up in the blood instead of being absorbed by cells in the body, and the body is starved of energy. - Prediabetes is a condition in which blood glucose levels or A1C levels are higher than normal but not high enough to be diagnosed as diabetes. People with prediabetes can substantially reduce their risk of developing diabetes by losing weight and increasing physical activity. - The two main types of diabetes are type 1 diabetes and type 2 diabetes. Gestational diabetes is a third form of diabetes that develops only during pregnancy. - Type 1 diabetes is caused by a lack of insulin due to the destruction of insulin-producing beta cells. In type 1 diabetesan autoimmune diseasethe bodys immune system attacks and destroys the beta cells. - Type 2 diabetesthe most common form of diabetesis caused by a combination of factors, including insulin resistance, a condition in which the bodys muscle, fat, and liver cells do not use insulin effectively. Type 2 diabetes develops when the body can no longer produce enough insulin to compensate for the impaired ability to use insulin. - Scientists believe gestational diabetes is caused by the hormonal changes and metabolic demands of pregnancy together with genetic and environmental factors. Risk factors for gestational diabetes include being overweight and having a family history of diabetes. - Monogenic forms of diabetes are relatively uncommon and are caused by mutations in single genes that limit insulin production, quality, or action in the body. - Other types of diabetes are caused by diseases and injuries that damage the pancreas; certain chemical toxins and medications; infections; and other conditions. |
What is (are) Renal Artery Stenosis ? | Renal artery stenosis is the narrowing of one or both renal arteries. Renal means kidney and stenosis means narrowing. The renal arteries are blood vessels that carry blood to the kidneys from the aortathe main blood vessel that carries blood from the heart to arteries throughout the body.
RVH is high blood pressure caused by RAS. Blood pressure is written with two numbers separated by a slash, 120/80, and is said as 120 over 80. The top number is called the systolic pressure and represents the pressure as the heart beats and pushes blood through the blood vessels. The bottom number is called the diastolic pressure and represents the pressure as blood vessels relax between heartbeats. A persons blood pressure is considered normal if it stays at or below 120/80. High blood pressure is a systolic pressure of 140 or above or a diastolic pressure of 90 or above.1 |
What is (are) Renal Artery Stenosis ? | The kidneys are two bean-shaped organs, each about the size of a fist. They are located just below the rib cage, one on each side of the spine. Every day, the two kidneys filter about 120 to 150 quarts of blood to produce about 1 to 2 quarts of urine, composed of wastes and extra fluid. |
What causes Renal Artery Stenosis ? | About 90 percent of RAS is caused by atherosclerosisclogging, narrowing, and hardening of the renal arteries.2 In these cases, RAS develops when plaquea sticky substance made up of fat, cholesterol, calcium, and other material found in the bloodbuilds up on the inner wall of one or both renal arteries. Plaque buildup is what makes the artery wall hard and narrow.
Most other cases of RAS are caused by fibromuscular dysplasia (FMD)the abnormal development or growth of cells on the renal artery wallswhich can cause blood vessels to narrow. Rarely, RAS is caused by other conditions. |
Who is at risk for Renal Artery Stenosis? ? | People at risk for artherosclerosis are also at risk for RAS. Risk factors for RAS caused by artherosclerosis include
- high blood cholesterol levels - high blood pressure - smoking - insulin resistance - diabetes - being overweight or obese - lack of physical activity - a diet high in fat, cholesterol, sodium, and sugar - being a man older than 45 or a woman older than 55 - a family history of early heart disease
The risk factors for RAS caused by FMD are unknown, but FMD is most common in women and people 25 to 50 years of age.3 FMD can affect more than one person in a family, indicating that it may be caused by an inherited gene. |
What are the symptoms of Renal Artery Stenosis ? | In many cases, RAS has no symptoms until it becomes severe.
The signs of RAS are usually either high blood pressure or decreased kidney function, or both, but RAS is often overlooked as a cause of high blood pressure. RAS should be considered as a cause of high blood pressure in people who
- are older than age 50 when they develop high blood pressure or have a marked increase in blood pressure - have no family history of high blood pressure - cannot be successfully treated with at least three or more different types of blood pressure medications
Symptoms of a significant decrease in kidney function include
- increase or decrease in urination - edemaswelling, usually in the legs, feet, or ankles and less often in the hands or face - drowsiness or tiredness - generalized itching or numbness - dry skin - headaches - weight loss - appetite loss - nausea - vomiting - sleep problems - trouble concentrating - darkened skin - muscle cramps |
