A rectal prolapse occurs when part of or the entire wall of the rectum slides out of place and can stick out of the anus. A partial prolapse happens when the lining of the rectum falls out. A complete prolapse means the entire rectal wall slides out of place. When an internal prolapse occurs, a part of the wall of the colon or rectum may slide over another part.
Avoiding constipation and straining during bowel movements can help prevent prolapses. Surgery is required to heal a complete prolapse or a partial prolapse that doesn’t heal on its own.
