Ulcerative Colitis
Topic Overview
Is this topic for you?Ulcerative colitis and Crohn's disease are the most common types of inflammatory bowel disease. Ulcerative colitis affects only the colon and rectum. Crohn’s can affect any part of the digestive tract. To learn more about Crohn’s disease, see the topic Crohn’s Disease. What is ulcerative colitis?Ulcerative colitis is a disease that causes inflammation and sores (ulcers) in the lining of the large intestine, or colon. It usually affects the lower section (sigmoid colon) and the rectum. But it can affect the entire colon. In general, the more of the colon that’s affected, the worse the symptoms will be. See a picture of the
colon Ulcerative colitis can affect people of any age, but most people who have it are diagnosed before the age of 30. What causes ulcerative colitis?Experts are not sure what causes ulcerative colitis. They think it might be caused by the immune system overreacting to normal bacteria in the digestive tract. Or other kinds of bacteria and viruses may cause the disease. Ulcerative colitis is not caused by stress, as people once thought. But if you have ulcerative colitis, stress can make it worse. You are more likely to get ulcerative colitis if other people in your family have it. What are the symptoms?The main symptoms are:
Some people also may have a fever, may not feel hungry, and may lose weight. In severe cases, people may have diarrhea 10 to 20 times a day. Ulcerative colitis can also cause other problems, such as joint pain, eye problems, or liver disease. But these symptoms are more common in people who have Crohn’s disease. In most people, the symptoms come and go. Some people go for months or years without symptoms (remission). Then they will have a flare-up. About 5 to 10 out of 100 people with ulcerative colitis have symptoms all the time.1 Ulcerative colitis sometimes leads to more serious problems. It can cause scarring of the bile duct. This can lead to liver damage. In rare cases, severe disease causes the colon to swell to many times its normal size (toxic megacolon). This can be deadly and needs emergency treatment. People who have ulcerative colitis for 8 years or longer have a greater chance of getting colon cancer.2 Talk to your doctor about your need for cancer screening. Screening tests help find cancer early, when it is easier to treat. How is ulcerative colitis diagnosed?To diagnose ulcerative colitis, doctors ask about the symptoms, do a physical exam, and do a number of tests. Testing can help the doctor rule out other problems that can cause similar symptoms, such as Crohn’s disease, irritable bowel syndrome, or diverticulitis. Tests that may be done include:
How is it treated?Ulcerative colitis affects everyone differently. Your doctor will help you find treatments that reduce your symptoms and help you avoid new flare-ups. If your symptoms are mild, you may only need to use over-the-counter medicines for diarrhea (such as Imodium A-D). Talk to your doctor before you take these medicines. Doctors often prescribe medicines to reduce inflammation, such as:
Some people find that certain foods make their symptoms worse. If this happens to you, it makes sense to avoid those foods. But be sure to eat a healthy, varied diet to keep your weight up and stay strong. If you have severe symptoms and medicines don't help, you may need surgery to remove part or all of your colon. Removing the entire colon cures ulcerative colitis. It also prevents colon cancer. But it does have some serious risks. Still, most people who have surgery are glad they did.3, 4 How will ulcerative colitis affect your life?Ulcerative colitis can be hard to live with. During a flare-up it may seem like you are always running to the bathroom. This can be embarrassing and can take a toll on how you feel about yourself. Not knowing when the disease will strike next can be stressful. Stress may actually make the problem worse. If you are having a hard time, seek support from family, friends, or a counselor. Or look for an ulcerative colitis support group. It can be a big help to talk to others who are coping with this disease. Frequently Asked Questions

CauseThe cause of ulcerative colitis is unknown. Studies suggest that this and other inflammatory bowel diseases may result from an abnormal response by the body's immune system to normal intestinal bacteria.1 Disease-causing bacteria and viruses also may play a role in causing the condition. Ulcerative colitis can run in families—some people may have a genetic tendency to develop the condition. SymptomsThe symptoms of ulcerative colitis may include:
You also may develop symptoms and complications outside the digestive tract, such as joint pain, eye problems, skin rash, or liver disease. However, some of these problems are generally more common in Crohn's disease, the other major inflammatory bowel disease. Other conditions with symptoms similar to ulcerative colitis include Crohn's disease, diverticulitis, irritable bowel syndrome (IBS), and colon cancer. What HappensThe course of ulcerative colitis varies greatly from one person to another. Some people may have only mild symptoms, and others may have severe symptoms or complications that, in unusual cases, may be life-threatening. Ulcerative colitis may be mild, moderate, or severe. It may be described as dependent on corticosteroids, unresponsive to steroids, or not active (in remission).
Ulcerative colitis Most people with ulcerative colitis have periods of remission that may last up to several years. These periods are interrupted by occasional flare-ups of moderate symptoms. Between 5% and 10% of people have symptoms all the time.1 Children may have the same symptoms as adults. In addition, children with ulcerative colitis may grow more slowly than normal and go through puberty later than expected. Complications and long-term effects
Some people who have ulcerative colitis also have irritable bowel syndrome (IBS), which is not as serious as ulcerative colitis. IBS causes abdominal pain along with diarrhea or constipation. Most women who have ulcerative colitis are able to become pregnant and usually have healthy babies. Symptoms may become worse during the first 3 months of pregnancy. Some medicines to treat the disease can be used during pregnancy. What Increases Your RiskYou have an increased risk of developing ulcerative colitis if you:
When To Call a DoctorCall a doctor immediately if you have been diagnosed with ulcerative colitis and you have any of the following:
If you have any of these symptoms and you have been diagnosed with ulcerative colitis, your disease may have gotten significantly worse. Some of these symptoms also may be signs of toxic megacolon, a condition in which the colon swells to many times its normal size. Toxic megacolon requires emergency treatment. Untreated toxic megacolon can cause the colon to leak or rupture, which can be fatal. People who have ulcerative colitis usually know their normal pattern of symptoms. Call your doctor if there is a change in your usual symptoms or if:
Watchful WaitingWatchful waiting is not appropriate when you have any of the above symptoms. If your symptoms are caused by ulcerative colitis, delaying the diagnosis and treatment may make the disease worse and increase your risk of complications. Even when the disease is in remission, your doctor will want to see you regularly to check for complications, some of which can be hard to detect. It is always appropriate to call your doctor's office for advice. Who To SeeHealth professionals who can diagnose ulcerative colitis include: For the treatment and management of ulcerative colitis, you are likely to be referred to a gastroenterologist. To be evaluated for surgery, you may be referred to a: To prepare for your appointment, see the topic Making the Most of Your Appointment Exams and Tests
Ulcerative colitis can be relatively easy to diagnose
because it normally affects only the
colon and
rectum The colon and rectum can be examined with flexible sigmoidoscopy or colonoscopy, tests in which a doctor examines the inside of the large intestine using a small, lighted scope. In general, colonoscopy is the preferred test because it can be used to examine the entire colon. However, flexible sigmoidoscopy may be all that is needed to diagnose ulcerative colitis. Both procedures can be used to take a sample (biopsy) of intestinal tissue. The diagnosis of ulcerative colitis is made by ruling out other causes of diarrhea and assessing the results of these tests. Other exams and tests that may be used to evaluate ulcerative colitis include:
A stool analysis (including a test for blood in the stool) is often done, depending on symptoms, to look for blood, signs of bacterial infection, parasites, or the presence of white blood cells. This test can be used to distinguish ulcerative colitis from irritable bowel syndrome (IBS), a less serious condition that sometimes has similar symptoms. The presence of white blood cells in stool indicates inflammation and infection but is not necessarily a sign of ulcerative colitis. However, white blood cells in stool mean that you do not have IBS. Stool analysis may be done during a flare-up of ulcerative colitis if there is concern that new symptoms are caused by another problem. You can collect a stool sample, or the doctor may obtain it during sigmoidoscopy or colonoscopy.
In about 10% of people who have symptoms, neither Crohn's disease nor ulcerative colitis can be diagnosed. These people have a form of inflammatory bowel disease called indeterminate colitis, which doctors believe is a combination of Crohn's disease and ulcerative colitis.6 Treatment OverviewTreatment for ulcerative colitis depends mainly on the severity of the disease and usually includes medicines to control symptoms, such as diarrhea, and changes in diet. A few people have symptoms that are persistent and severe, in some cases requiring treatment with additional medicines or surgery. The goals of treatment include:
Initial treatmentIf you don't have any symptoms of ulcerative colitis or if your disease is not active (in remission), you may not need treatment. If you do have symptoms, they usually can be managed with medicines to put the disease in remission. It often is easier to keep the disease in remission than to treat a flare-up. Mild symptoms may respond to antidiarrheal medicines and changes in your diet. Sometimes you may need to use enemas or suppositories. Talk with your health professional before taking antidiarrheals. Prescription medicines may be used to treat mild symptoms and keep the disease in remission. Usually, corticosteroids (such as hydrocortisone or prednisone) are given for a few weeks to control active disease. When your symptoms are under control, you may take aminosalicylates (such as sulfasalazine or mesalamine) to keep the disease in remission. Aminosalicylates relieve inflammation in the intestines. Moderate to severe symptoms usually require corticosteroids to control inflammation. The required dose of steroids may be higher than that needed to treat mild colitis. When inflammation goes away, you will take aminosalicylates to keep the condition in remission. For more information about making good food choices, see: Immunomodulator medicines, such as azathioprine (AZA) or 6-mercaptopurine (6-MP), also may be needed for severe cases that cannot be controlled with aminosalicylates alone. These medicines suppress the body's immune system to prevent inflammation. Immunomodulators also may be needed to avoid long-term use of steroids, which can cause side effects such as increased risk of infection and osteoporosis. For severe ulcerative colitis, when corticosteroids don't work, your doctor may have you try infliximab. Infliximab (Remicade) may work to put you in remission when other medicines don't. Infliximab has also been shown to help heal the lining of the intestine. Ongoing treatmentThe goal of ongoing treatment is to keep ulcerative colitis from causing symptoms (keep it in remission). Most people take aminosalicylates (such as sulfasalazine or mesalamine) to prevent symptoms from recurring. Aminosalicylates relieve inflammation in the intestines. If you do have flare-ups, you will be given corticosteroids (such as hydrocortisone or prednisone) to control the inflammation. Usually, steroids are given only long enough to control inflammation. If your condition is so severe that aminosalicylates alone cannot keep you in remission and you would need long-term use of steroids, you may take immunomodulator medicines (such as azathioprine [AZA], 6-mercaptopurine [6-MP], or cyclosporine). These strong medicines suppress the immune system to prevent inflammation. If these medicines don't work, your doctor may have you try infliximab (Remicade). Infliximab also blocks the inflammatory response in your body and helps reduce the inflammation in your colon. Your health professional will want to see you for a follow-up visit about every 6 months while your condition is stable and more frequently if you are having problems. If you are taking medicines, you may have laboratory tests every 2 to 3 months. Many people who have ulcerative colitis are so familiar with the course of their condition that they can handle minor flare-ups on their own. In some cases, you may be able to consult with your health professional on the phone for minor problems. Treatment if the condition gets worseYou may have to receive treatment in the hospital if you have severe, persistent ulcerative colitis with symptoms outside the digestive tract, such as fever or anemia. Treatment includes replacing fluids and electrolytes lost because of severe diarrhea. Your health professional may increase your dose of corticosteroids (such as hydrocortisone or prednisone) to control active disease or may increase your immunomodulator medicines (such as azathioprine [AZA], 6-mercaptopurine [6-MP], or cyclosporine) or infliximab to suppress your immune system. However, steroids are usually not used as long-term therapy because they do not keep ulcerative colitis in remission. Surgery may be necessary if your symptoms do not improve with
medicines or you have complications such as bleeding or perforation of the
intestine. Removal of the
large
intestine (colon) Some people who have precancerous changes in their colon may decide to have surgery to prevent cancer even if they have no symptoms. In some cases, people decide to have their colon removed to improve their quality of life and to eliminate the risk of colon cancer. PreventionYou cannot prevent ulcerative colitis because the cause is unknown. However, you can take steps to reduce the severity of the disease.
Antibiotics may make ulcerative colitis symptoms worse and should only be used when necessary. Home TreatmentIf ulcerative colitis does not cause symptoms, no treatment is needed. If you have only mild symptoms, antidiarrheal medicines and changes in diet and nutrition may help. For disease in the rectum alone, you can try topical medicines (suppository, enema, or foam). Ask your health professional about these products. For more information about making good food choices, see: Generally, doctors recommend that you do not use nonsteroidal anti-inflammatory drugs (NSAIDs, such as ibuprofen or naproxen). Studies have linked these pain relievers with flare-ups of ulcerative colitis.7 However, some people may be more likely to have flare-ups from NSAIDs than others. Talk to your health professional about whether to avoid these medicines. If you have had or are planning to have surgery that will create an opening from the intestines to the outside of the body through which stool passes (ostomy), you may feel self-conscious or embarrassed. After a period of adjustment, most people are able to resume all of their usual activities. In fact, you may feel better than before surgery because you may no longer suffer painful symptoms. Support groups are available for people with ostomies. Children with ulcerative colitis may feel self-conscious if they do not grow as fast as other children their age. Encourage your child to take medicine as prescribed. Offer your help with the treatment so that your child can feel better, start growing again, and lead a more normal life. Children tend to have a harder time managing ulcerative colitis than adults, so your support is especially important. MedicationsMedications usually are the treatment of choice for ulcerative colitis. They control or prevent inflammation in the intestines and help:
Medication ChoicesThe choice of medicine usually depends on the severity of the disease, the part of the colon affected, and whether complications are present.
If you are pregnant, talk to your health professional about which medicines are safe for you to take. Usually, aminosalicylates and corticosteroids are safe, especially when your doctor thinks that ulcerative colitis is more dangerous to the fetus than these medicines. Ask your doctor whether you can take medicines that suppress the immune system. These are used only when the benefit outweighs the potential harm to the fetus. A health professional can recommend medicines based on the stage of the pregnancy and the severity of your symptoms. Several studies have shown that the nicotine patch may help treat active ulcerative colitis. It is not yet known how long the benefits of the nicotine patch last or if the patch can help prevent flare-ups of ulcerative colitis. If the patch works, it most likely benefits people whose symptoms began or became worse after quitting smoking. However, due to the addictive power and other harmful effects of nicotine, most doctors still prefer to use traditional medicines to treat ulcerative colitis before trying the nicotine patch. What To Think AboutAminosalicylates are the most common medicines used to treat ulcerative colitis. Most of the time, these medicines are all a person needs to keep the disease in remission (a period of time with no symptoms). When aminosalicylates do not work, corticosteroids are most often the next medicine tried. Corticosteroids will only be used long enough to stop the inflammation in your colon. After the inflammation goes down, aminosalicylates will most likely be used to maintain remission. If aminosalicylates are not strong enough to keep you in remission, or if corticosteroids don't work, your doctor may have you try different medicines. These medicines include immunomodulators, cyclosporine, and infliximab. All of these medicines control the immune response in your body and will decrease the amount of inflammation in your intestine. The inflammation is what causes the symptoms of ulcerative colitis. SurgeryUlcerative colitis affects only the large intestine, so surgery that removes the entire large intestine can cure the disease. Some people who have ulcerative colitis in the entire colon (pancolitis) eventually need surgery to remove the colon. People may need surgery for ulcerative colitis in several situations, such as when other therapy fails to manage symptoms, when holes develop in the large intestine, or if dysplasia is found during colonoscopy or biopsy. Surgery ChoicesRemoval of the colon to cure ulcerative colitis involves one of these surgeries:
What To Think AboutIleoanal anastomosis is performed most often. Proctocolectomy with ileostomy is preferred for people who cannot tolerate anesthesia for a long period of time because of illness or age. Both children and adults may have ileoanal anastomosis, which may be done in stages to reduce the risk of complications. A temporary ileostomy is created first, with the ileum pouch completed 3 to 6 months later. Surgery can improve a child's well-being and quality of life and restore normal growth and sexual development. In the past, many people who had surgery for IBD had an ileostomy and wore an ostomy bag outside the abdomen. Newer surgeries like ileoanal anastomosis or continent ileostomy can eliminate the need for an ostomy bag with fairly good results when they are done by a trained surgeon. Traditional ostomy surgery is easier and may have fewer risks and complications than the newer procedures, but some people may be less satisfied with the results. People with ulcerative colitis may choose to have their colon removed because their symptoms cause a poor quality of life. They also may want the surgery to prevent the possibility of colon cancer. In most cases, surgery can be scheduled at your convenience. Emergency surgery usually is not needed unless an acute attack causes toxic megacolon, severe uncontrolled bleeding, or a spontaneous rupture in the intestine. The risk of complications after surgery can be high if surgery is done during a severe or rapidly worsening attack or if emergency surgery is needed. If toxic megacolon has developed, surgery may be the only option to save a person's life. Other TreatmentEven though there is little scientific proof that it works, many people with ulcerative colitis consider nontraditional or complementary medicine in addition to prescription medicines. They may turn to these alternatives because there is no complete cure other than removal of the colon. Other reasons for seeking complementary medicine include:
Other Treatment ChoicesComplementary medicineThe various complementary therapies include:
Probiotics and fatty acids are the most promising complementary therapies being studied for ulcerative colitis. But there is still not much known about their value. As with any treatment, talk with your doctor before using complementary medicines or therapies. What To Think AboutYou may want to seek professional counseling or social support from family, friends, or clergy. Ulcerative colitis can affect every aspect of your life. Research has shown that strong social support can reduce psychological stress and disease activity.8 Other Places To Get HelpOrganizations
