What's the difference between Crohn's Disease and Ulcerative Colitis


When studying inflammatory bowel disease (IBS), both Crohn’s and ulcerative colitis have come up. Can anyone give a good comparison between the two?


Good question. As you stated, both ulcerative colitis (UC) and Crohn’s disease (CD) are under the umbrella term IBS. Here are some important differentiators and what you may be tested on in school:

Ulcerative Colitis Crohn's Disease
Location Colon only Entire GI tract
Thickness Mucosal layer only Entire intestinal wall
Skip lesions No Yes
