Ulcerative Colitis


Ulcerative colitis is a chronic disease of the colon (large intestine). Ulcers (sores) form on the inner lining of your colon and cause bleeding and inflammation.


Informed consent

is a legal document that explains the tests, treatments, or procedures that you may need. Informed consent means you understand what will be done and can make decisions about what you want. You give your permission when you sign the consent form. You can have someone sign this form for you if you are not able to sign it. You have the right to understand your medical care in words you know. Before you sign the consent form, understand the risks and benefits of what will be done. Make sure all your questions are answered.


You may need to rest in bed until you are feeling better. Your healthcare provider will tell you when it is okay to get out of bed. If you are not allowed out of bed, you can still exercise your legs. Do this by lifting one leg off the bed and drawing big circles with your toes. Repeat with the other leg. Call your healthcare provider before you get up for the first time. If you feel weak or dizzy, sit or lie down right away.

Intake and output

may be measured. Healthcare providers will keep track of the amount of liquid you are getting. They also may need to know how much you are urinating. Ask healthcare providers if they need to measure or collect your urine.


Medicines may be given to decrease inflammation or control your immune system.


  • Blood tests: You may need blood taken to give healthcare providers information about how your body is working. The blood may be taken from your hand, arm, or IV.
  • A bowel movement sample may show the germ causing your illness. This helps healthcare providers learn what medicine is best to treat you.
  • Colonoscopy or sigmoidoscopy are procedures that help your healthcare provider see the inside of your colon. He will use a flexible tube with a small light and camera on the end. During a sigmoidoscopy, your healthcare provider will only look at your rectum and lower colon. During a colonoscopy, he will look at the full length of your colon. He may remove a small amount of tissue from the colon for a biopsy.


  • A blood transfusion is used to give you whole or parts of blood through an IV. Blood is tested for diseases, such as hepatitis and HIV, to be sure it is safe.
  • Surgery may be needed to remove all or part of your colon. Surgery is the only cure for ulcerative colitis. Several types of surgery can be done depending on how bad your ulcerative colitis is and your lifestyle. Your healthcare provider can help you decide which surgery is best for you.


If not treated, ulcerative colitis may lead to dehydration, malnutrition, and severe anemia (low blood iron). Ulcerative colitis may increase your risk for colorectal cancer and may also affect other parts of the body. There may be swelling of your joints, eyes, or mouth. You may also have increased risk of skin problems, kidney stones, gallstones, spine problems, and liver disease.
