Question: what are the major differences between ulcerative colitis and crohn's disease?
Answer: 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 inner most lining of the colon while Crohn's disease can occur in all the layers of the bowel walls.
