Crohn's also involves all of the layers of the gut wall, while UC only involes the inner, mucosal lining of the colon. Therefore, Crohn's commonly causes fistulas, blockage from scar tissue, and less commonly perforation. These can all be life-threatening. UC, on the other hand, rarely causes life-threatening conditions (although perforation can occur in certain circumstances when the disease is poorly controlled.) But statistically, the life expectancy for UC is no different than the general population.
