Complications of rectal prolapse can include:faecal incontinence; difficulty pushing your prolapsed rectum back in place-this may become impossible; bleeding or ulcers on the prolapsed part of your rectum. In rare cases, parts of your rectum can become trapped, cutting off the blood supply causing the protruding mass of tissue to die(strangulated prolapse).This can be extremely painful and may cause the prolapsed part of your rectum to swell. If this happens, seek emergency treatment from the accident and emergency department of your local hospital.
