Rectal prolapse occurs when part or all of the wall of the rectum slides out of place, sometimes sticking out of the anus. See a picture of rectal prolapse. There are three types of rectal prolapse. In severe cases of rectal prolapse, a section of the large intestine drops from its normal position as the tissues that hold it in place stretch. Typically there is a sharp bend where the rectum begins.
