Ulcerative colitis

Ulcerative colitis is a type of inflammatory bowel disease (IBD) that causes inflammation and sores (ulcers) in the inner lining of the colon and rectum. It causes diarrhea, abdominal pain, and rectal bleeding.

Ulcerative colitis is a chronic condition that may flare up many times during a person's life. Some people may have long periods without symptoms or may have only mild symptoms, while other people have symptoms that are more persistent and severe.

Ulcerative colitis is treated with medicines or with surgery to remove the diseased colon. Treatment depends on the severity of the attacks and the person's age. Children and older people may have specific problems that require special care.
