Crohn’s Disease

Ulcerative colitis and Crohn’s disease are two types of Inflammatory Bowel Disease (IBD). The large intestine (colon) is inflamed in ulcerative colitis, and this involves the inner lining of the colon. In Crohn’s disease the inflammation extends deeper into the intestinal wall. Crohn’s disease can also involve the small intestine (ileitis), or can involve both the small and large intestine (ileocolitis).
