› The risk of cancer
The risk of cancer is low in Crohn’s disease while it is high in ulcerative colitis, especially after ten years of the disease onset.
› Toxic megacolon
It is rare in Crohn’s disease because it usually doesn’t involve the colon and rectum. But, in ulcerative colitis, the risk is high. Toxic megacolon is a life-threatening complication of ulcerative colitis.
