Definition & Facts of Fecal Incontinence

In this section:

What is fecal incontinence?

Fecal incontinence, also called accidental bowel leakage, is the accidental passing of bowel movements—including solid stools, liquid stools, or mucus—from your anus.

The most common type of fecal incontinence is called urge incontinence. When you have urge incontinence, you feel a strong urge to have a bowel movement but cannot stop it before reaching a toilet. If you have urge incontinence, your pelvic floor muscles may be too weak to hold back a bowel movement due to muscle injury or nerve damage.

Another type of fecal incontinence is called passive incontinence. When you have passive incontinence, leakage occurs without you knowing it. If you have passive incontinence, your body may not be able to sense when your rectum is full.

Fecal incontinence can be upsetting and embarrassing. Some people may feel ashamed and try to hide the problem. You may be afraid or embarrassed to talk about fecal incontinence with your doctor. However, talking openly and honestly with your doctor is important in diagnosing and treating your fecal incontinence.
