People with a autism, psychiatric disorders and whip worms have it more commonly. It is more common with constipation or with straining. There are 3-5 different types depending upon which classification system is used. Small prolapse can go back inside and appear to go away.

Rectal prolapse: Rectal prolapse is not common. According to uptodate literature reviews, the incidence is 0.25 to 0.42% in the adult population, and prevalence is estimated at 1% in adults over age 65. I agree with dr. Jacobson that chronic diarrhea is a risk factor. Other risk factors include female gender, multiparity with vaginal delivery, prior pelvic surgery, chronc constipation & straining, etc.
