The term "redundant colon" describes a large intestine (colon) that is longer than normal and as a result has repetitive, overlapping loops. Typically, this is a normal anatomic variation. It usually causes no symptoms and needs no treatment. A redundant colon may be found incidentally on a colon X-ray (barium enema) done for some other reason. Rarely, it causes a serious complication if it twists around itself (volvulus) and obstructs the colon. This causes cramping abdominal pain and usually warrants prompt medical attention.
