Fecal Incontinence

 

  • Fecal Incontinence is the inability to control your bowels. When you feel the urge to have a bowel movement, you may not be able to hold it until you can get to a toilet. Or stool may leak from the rectum unexpectedly.

    More than 5.5 million Americans have Fecal Incontinence. It affects people of all ages—children as well as adults. Fecal Incontinence is more common in women than in men and more common in older adults than in younger ones. It is not, however, a normal part of aging.

    Loss of bowel control can be devastating. People who have Fecal Incontinence may feel ashamed, embarrassed, or humiliated. Some don't want to leave the house out of fear they might have an accident in public. Most try to hide the problem as long as possible, so they withdraw from friends and family. The social isolation is unfortunate but may be reduced because treatment can improve bowel control and make incontinence easier to manage.

    Fecal Incontinence can have several causes:

    Constipation
    Damage to the anal sphincter muscles
    Damage to the nerves of the anal sphincter muscles or the rectum
    L loss of storage capacity in the rectum
    Diarrhea
    Pelvic floor dysfunction

    Constipation is one of the most common causes of Fecal Incontinence. Constipation causes large, hard stools to become lodged in the rectum. Watery stool can then leak out around the hardened stool. Constipation also causes the muscles of the rectum to stretch, which weakens the muscles so they can't hold stool in the rectum long enough for a person to reach a bathroom.

    Muscle Damage
    Fecal Incontinence can be caused by injury to one or both of the ring-like muscles at the end of the rectum called the anal internal and/or external sphincters. The sphincters keep stool inside. When damaged, the muscles aren't strong enough to do their job, and stool can leak out. In women, the damage often happens when giving birth. The risk of injury is greatest if the doctor uses forceps to help deliver the baby or does an episiotomy, which is a cut in the vaginal area to prevent it from tearing during birth. Hemorrhoid surgery can damage the sphincters as well.

    Nerve Damage
    Fecal Incontinence can also be caused by damage to the nerves that control the anal sphincters or to the nerves that sense stool in the rectum. If the nerves that control the sphincters are injured, the muscle doesn't work properly and incontinence can occur. If the sensory nerves are damaged, they don't sense that stool is in the rectum. You then won't feel the need to use the bathroom until stool has leaked out. Nerve damage can be caused by childbirth, a long-term habit of straining to pass stool, stroke, and diseases that affect the nerves, such as diabetes and multiple sclerosis.

    Loss of Storage Capacity
    Normally, the rectum stretches to hold stool until you can get to a bathroom. But rectal surgery, radiation treatment, and inflammatory bowel disease can cause scarring that makes the walls of the rectum stiff and less elastic. The rectum then can't stretch as much and can't hold stool, and fecal incontinence results. Inflammatory bowel disease also can make rectal walls very irritated and thereby unable to contain stool.

    Diarrhea
    Diarrhea, or loose stool, is more difficult to control than solid stool that is formed. Even people who don't have Fecal Incontinence can have an accident when they have diarrhea.
