Ulcerative colitis involves inflammation of the inner lining of the colon and rectum.
Crohn's disease may involve inflammation anywhere in the digestive tract from the mouth to the rectum. The following table identifies some of the differences and similarities between ulcerative colitis and Crohn's disease. However, medication is available to reduce the symptoms of moderate and severe cases. Asacol tablets are indicated for the treatment of mildly to moderately active ulcerative colitis and for the maintenance of remission of ulcerative colitis. Asacol is generally well tolerated.
