Compare types of colitis, ibd or crohn?

IBD (Crohn's vs UC): Ibd (inflammatory bowel disease) includes a spectrum of disorders that result in gut inflammation with systemic manifestations. Gut involvement in ulcerative colitis is limited to the lining of the colon whereas in crohn's disease there is transmural (full-thickness) inflammation that can involve any portion of the gut (from mouth to anus). See my other healthtap answers on the subject too.

I believe you mean: Ulcerative colitis or Crohn's, both of which are IBD's. Both can affect the colon causing inflammation (colitis.) In Crohn's disease, the inflammation tends to involve the whole depth of the colon, leading to scarring and possible narrowing. With ulcerative colitis, inflammation is limited to the inner lining of the colon. Ulcerative colitis is cured with colectomy, Crohn's is not.
