A<unk>  occurs when walls of the rectum have<unk> d to such a degree that they protrude out of the anus and are visible outside the body. However, most researchers agree that there are 3 to 5 different types of<unk> , depending on whether the<unk> d section is visible externally, and whether the full or only partial thickness of the rectal wall is involved.<unk>  may occur without any symptoms, but depending upon the nature of the<unk>  there may be mucous discharge (mucus coming from the anus), rectal bleeding, degrees of fecal incontinence and obstructed defecation symptoms.<unk>  is generally more common in elderly women, although it may occur at any age and in either sex. It is very rarely life-threatening, but the symptoms can be debilitating if left untreated. Most external<unk>  cases can be treated successfully, often with a surgical procedure. Internal<unk> s are traditionally harder to treat and surgery may not be suitable for many patients.
