what causes anus leakage
Causes of Bowel Incontinence. The most common cause of bowel incontinence is damage to the muscles around the anus (anal sphincters). Vaginal childbirth can damage the anal sphincters or their nerves.That's why women are affected by accidental bowel leakage about twice as often as men.uring a physical examination, a doctor may check the strength of the anal sphincter muscle using a gloved finger inserted into the rectum. Other tests may be helpful in identifying the cause of bowel incontinence, such as: Stool testing. If diarrhea is present, stool testing may identify an infection or other cause.
