Ulcerative Colitis


content provided by Healthwise

Cause

The cause of ulcerative colitis is unknown. Studies suggest that this and other inflammatory bowel diseases may result from an abnormal response by the body's immune system to normal intestinal bacteria.1 Disease-causing bacteria and viruses also may play a role in causing the condition.

Ulcerative colitis can run in families—some people may have a genetic tendency to have it.
