If you have any of these symptoms and you have been
diagnosed with Crohn's disease, your condition may have become much
worse. Some of these symptoms also may be signs of
toxic megacolon. This is a rare complication of Crohn's
disease that requires emergency treatment. Untreated toxic megacolon can cause
the colon to leak or rupture, which can be fatal.
