Crohn's Disease - Cause

The cause of Crohn's disease is unknown. This disease 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.

Crohn's disease can run in families, so some people may be more likely than others to develop the condition when exposed to something that triggers an immune reaction. Environmental factors may also play a role in causing this disease.
