Rectal prolapse is when the rectal walls have prolapsed to a degree where they protrude out the anus and are visible outside the body. Rectal prolapse may occur without any symptoms, but depending upon the nature of the prolapse there may be mucous discharge mucus coming from the anus , rectal bleeding , degrees of fecal incontinence and obstructed defecation symptoms.
