Crohn disease and ulcerative colitis are chronic inflammatory bowel diseases (IBDs). Although they have similar symptoms, they are different disease processes. Ulcerative colitis affects only the colon (large intestine). Crohn disease may involve the entire gastrointestinal (GI) tract but most often occurs in the ileum (the last part of the small intestine). Irritable bowel syndrome has symptoms similar to IBD, but is not an immune disease. The inflammation seen in Crohn disease has similarities to the disease process of other immune diseases such as rheumatoid arthritis: the body's immune system reacts to antigens (proteins from the environment such as bacteria or food components that the body senses as invaders) and this causes the inflammatory process. The April 9, 2008, issue of JAMA includes an article about Crohn disease.
