Ulcerative Colitis – Harvard Medical School
Ulcerative colitis is an inflammatory bowel disease. People with ulcerative colitis develop inflammation in the lining of the large intestine (colon). The inflammation leads to the formation of ulcers. This can cause bleeding, diarrhea, weight loss, and fatigue. Some people with ulcerative
colitis may have only occasional symptoms. For others, the symptoms can be constant. Medications can usually control the inflammation. But sometimes surgery is required.
