Crohn's disease and ulcerative colitis and are the two main forms of inflammatory bowel diseases. The conditions are characterized by chronic inflammation of the digestive tract. Ulcerative colitis is usually limited to the colon (the large bowel) and rectum, while Crohn's disease may involve the stomach but typically involves the small bowel and beginning of the large bowel. In Crohn's disease, there are healthy parts of the intestine mixed in-between inflamed areas. Ulcerative colitis, on the other hand, is continuous inflammation of the colon. Ulcerative colitis only affects the innermost lining of the colon while Crohn's disease can occur in all the layers of the bowel walls.
