Ulcerative Colitis

A type of inflammatory bowel disease that affects the large intestine (colon) and rectum. The disease usually begins in the rectal area and may eventually extend through the entire large intestine. Repeated swelling (inflammation) leads to thickening of the wall of the intestine and rectum with scar tissue. Death of colon tissue or severe infection may occur with severe disease. Symptoms include abdominal pain and cramping that generally disappear following a bowel movement, gurgling or other abdominal sounds, fever, rectal pain and weight loss.
