What is Ulcerative Colitis?

Outline of man showing gastrointestinal system.

Ulcerative colitis is a long-term (chronic) disease. It causes swelling (inflammation) and sores (ulcers) in the inner lining of the rectum and colon. It is a form of inflammatory bowel disease (IBD). No one knows for sure what causes it. But symptoms can be treated. People with this disease can lead full, active lives.

Symptoms of ulcerative colitis

Symptoms often have to do with bowel movements. You may have:

  • Frequent, loose bowel movements

  • Blood and pus in stools, or rectal bleeding

  • Feeling that you didn’t fully empty your bowels (incomplete bowel movement)

  • Feeling that you need to have a bowel movement right away (urgency)

  • Belly (abdominal) cramps

  • Loss of appetite, weight loss

  • Nausea

  • Feeling very tired (fatigue)

  • Anemia

  • Joint pain

  • Rectal pain that comes and goes

  • Eye pain or redness

  • Certain rashes

Your treatment options

Your healthcare provider will ask about your past health and family history. He or she will also give you a physical exam. You may also need these tests:

  • Lab tests. Your blood and stool will be checked.

  • Endoscopies of the large intestine. These tests are the most accurate way to diagnose this condition. They use a long, flexible tube with a tiny light and camera on one end. They check the inside of your large intestine.

Medicines

Your healthcare provider will try to find the medicines that work best for you. You may take:

  • A type of anti-inflammatory medicine (called 5-ASA compounds or mesalamine) to help reduce swelling and inflammation in the intestines

  • Corticosteroids to help reduce inflammation

  • Antibiotics to fight bacteria, if there is an infection

  • Medicines to control your body’s immune system (such as immunomodulators or biologics)

Lifestyle changes

  • Certain foods can make your symptoms worse. You may need to change what you eat. Stay away from any food that makes your symptoms worse. These foods vary from person to person. But certain foods cause symptoms in many people. These include high-fiber foods (such as fresh vegetables) and high-fat foods (such as dairy products and red meat). Keep track of foods that cause you problems.

  • Stress can also worsen symptoms. Reducing stress may help. Methods like relaxation exercises, meditation, and deep breathing can help you control stress. Your healthcare provider may be able to tell you more about these.

If surgery is needed

Surgery may help control or even cure ulcerative colitis. It is done to take out a severely affected part of the colon. If this is an option for you, your provider can tell you more.
