Rectal prolapse occurs when part of the large intestine’s lowest section (rectum) slips outside the muscular opening at the end of the digestive tract (anus). The prolapsed rectum can cause fecal incontinence. Rectal prolapse can be sometimes treated with stool softeners, suppositories, and other medications. Surgery is usually needed to treat rectal prolapse.
