What might cause rectal prolapse?

Rectal prolapse occurs when the rectum descends and protrudes through the anus, and several factors can contribute to its development. Trauma from childbirth is a significant cause because the process can weaken the pelvic floor muscles and supporting structures. During vaginal delivery, the increased pressure and stretching can damage the connective tissues and muscles in the pelvic region. This can lead to a loss of support necessary to keep the rectum in its proper position, increasing the likelihood of prolapse later on.

While obesity, changes in diet, aging, and excessive exercise can affect pelvic health, they do not directly involve the mechanical trauma that childbirth inflicts, making trauma from childbirth a more specific and critical factor in causing rectal prolapse.
