Colon ulcers seen in endoscopy
Ulcerative colitis is a severe and potentially life-threatening inflammation and subsequent ulceration of the large intestine (colon). Repeated attacks cause thickening and scarring of the colon to the point where it cannot adequately undertake its task of absorbing excess fluid from the faeces. The cause is unknown, but it is more common in Whites than in Blacks and Orientals, and six times more common in Jews than other Caucasians. The overall incidence in developed countries is about one in every thousand people.
