A prolapse is when part of our body moves down from its normal position. In a rectal prolapse, part of the rectum slips down and protrudes from the anus.
An internal prolapse (rectal intussusception) is where the colon doesn’t fall outside the anus, but slips into the lower sections of the rectum. This can result in an obstruction, causing patients to experience difficulty opening their bowels.
While men can suffer from this condition, it’s very rare. Due to differences in pelvic anatomy, the majority of prolapse cases affect women.
There are multiple causes but, generally speaking, it’s due to weakness in the muscles and connective tissue, which allows the large bowel to prolapse through the anus.
This weakness can happen after pregnancy, or develop with age, meaning that women over 60 are most likely to be affected by a prolapse.
