Collagenous colitis is a newly-recognized disease of the colon. On sigmoidoscopy or colonoscopy the bowel lining appears to be normal but microscopic examination of biopsies shows inflammation and the presence of a band-like substance called collagen which is a component of scar tissue.
What foods to avoid if you have collagenous colitis?
Avoid beverages that are high in sugar or sorbitol or contain alcohol or caffeine, such as coffee, tea and colas, which may aggravate your symptoms. Choose soft, easy-to-digest foods. These include applesauce, bananas, melons and rice. Avoid high-fiber foods such as beans and nuts, and eat only well-cooked vegetables.
