Can a person bleed to death with colitis?

Colitis and death. Colitis - inflammation of the colon - can be caused by many different things including ischemea (inadequate blood supply). Rarely this cause leads to severe bleeding and sudden death. Infections, ulcerative colitis, crohn's disease can cause many symptoms but rarely result direclty in death (uc is associated with cancer, however). Bleeding can occur without colitis and this can (rarely) be fatal.
