A 31-year-old member asked:

Why's it the fact that you get bleeding with ulcerative colitis but not with crohn's?

Crohn's colitis: Can cause bleeding too, but less frequently. Ulcerative colitis is a disease that affects mainly the mucosa or the inner lining, so rectal bleeding is more common. Crohn's colitis, in contrast, affects the entire wall of the colon, so perforations and fistulas are more common.
