Ulcerative colitis (UC) is a disease in which the lining of the colon, also called the large intestine, becomes inflamed. This inflammation destroys the cells that normally line the colon wall. As a result, sores or ulcers develop in those damaged areas.
Experts estimate that over 700,000 Americans have ulcerative colitis and the symptoms can be quite uncomfortable. In this video, Dr. Holly Atkinson explains what someone with UC may experience for the different types of ulcerative colitis. Symptoms of ulcerative colitis might occur only rarely, or they might come and go as part of the chronic condition. You may experience diarrhea or constipation, mild abdominal pain, mucus discharge from the rectum, and occasional bloody bowel movements.
For reasons that are not yet clearly understood, people with UC can also develop inflammation elsewhere beyond the colon. This inflammation often affects large joints like hips and knees that causes swelling and pain.
