Crohn’s Disease

Crohn’s disease is a type of inflammatory bowel disease (IBD) also called regional enteritis. It can affect any part of the gastrointestinal tract. Risk factors and complications include bowel obstruction and skin rashes such as pyoderma gangrenosum. There is increased risk of bowel cancer due to bowel obstruction. Crohn’s is not an autoimmune disease.
Crohn’s disease is an uncommon condition and not curable. Because of this the primary goal of treatment of Crohn’s disease is to reduce inflammation. Where corticosteroids may help to improve the disease immunosuppressants are used to decrease inflammation.
