Rectal Prolapse
What is rectal
prolapse?
Rectal prolapse is a condition in which the rectum (the lower end of the colon,
located just above the anus) becomes stretched out and protrudes out of the
anus. Weakness of the anal sphincter muscle is often associated with rectal
prolapse at this stage, resulting in leakage of stool or mucus. While the
condition occurs in both sexes, it is much more common in women than men.
Why does it occur?
Several factors may contribute to the development of rectal prolapse. It may
come from a lifelong habit of straining to have bowel movements or as a late
consequence of the childbirth process. Rarely, there may be a genetic
predisposition. It seems to be a part of the aging process in many patients who
experience stretching of the ligaments that support the rectum inside the pelvis
as well as weakening of the anal sphincter muscle. Sometimes rectal prolapse
results from generalized pelvic floor dysfunction, in association with urinary
incontinence and pelvic organ prolapse as well. Neurological problems, such as
spinal cord transection or spinal cord disease, can also lead to prolapse. In
most cases, however, no single cause is identified.
Is rectal prolapse the
same as hemorrhoids?
Some
of the symptoms may be the same: bleeding and/or tissue that protrudes from the
rectum. Rectal prolapse, however, involves a segment of the bowel located higher
up within the body, while hemorrhoids develop near the anal opening.
