Crohn's disease causes inflammation of the gastrointestinal tract, most commonly the lower part of the small intestine (the ileum).
The U.S. National Digestive Diseases Information Clearinghouse says potential complications of Crohn's include:
- A blocked intestine.
- Ulcers and fistulas, which are tunnel-like abnormal passageways that often become infected.
- Tiny tears, called fissures, in the membrane of the anus.
- Nutritional deficiencies.
- Skin problems.
- Gallstones or kidney stones.
- Inflammation of the eyes or mouth.
