What causes rectal prolapse?

Rectal prolapse, also known as procidentia, is mainly caused by the following factors: 1. Congenital factors: In some patients, underdevelopment of rectal and pelvic tissues—such as weak or insufficient levator ani muscles or pelvic floor fascia—leads to inadequate fixation of the rectum. 2. Acquired factors: Prolonged increased intra-abdominal pressure, such as from chronic coughing or excessive straining during defecation, as well as poor bowel habits like spending long periods on the toilet, may contribute to rectal prolapse. 3. Disease-related factors: Anorectal conditions such as internal hemorrhoids, constipation, and diarrhea, as well as systemic diseases like malnutrition and diabetes, may trigger or exacerbate rectal prolapse. To prevent rectal prolapse, it is recommended to maintain healthy lifestyle habits, such as regular bowel movements and avoiding prolonged sitting on the toilet, and to promptly treat related medical conditions. If symptoms of rectal prolapse occur, timely medical consultation is essential to identify the underlying cause and initiate appropriate treatment.
