Crohn's Disease

What is Crohn's Disease?

Crohn's is a form of chronic inflammatory bowel disease that occurs in the deep layers of the intestinal wall and has periods of remission (time when you feel well) and relapse (when you feel ill). The most common area affected is the lower part of the small intestine just before it meets the colon, this is known as the ileum. Crohn's disease can infrequently affect any part of the upper gastrointestinal tract. Aphthous ulcers, which are similar to canker sores, are common. Ulcers can also occur in the esophagus, stomach and upper small intestine (duodenum).
