Bowel incontinence, also called fecal incontinence, is a loss of bowel control that results in involuntary fecal elimination. Severity can range from an infrequent involuntary passage of small amounts of stool to a total loss of bowel control. Some people with bowel incontinence feel the urge to have bowel movements but are not able to wait to reach a bathroom. Other people do not feel the sensation of a pending bowel movement and have a complete lack of bowel control. Bowel incontinence can be an embarrassing condition, but it can improve with treatment.
Normal bowel control relies on the proper function of the pelvic muscles, the rectum (the lower end of the large intestine), the sphincter muscles (the muscles in the anus), and the nervous system. Injury to any of these areas can result in bowel incontinence. Common causes of bowel incontinence include:
Chronic constipation can lead to a fecal impaction. This happens when a stool gets stuck in the rectum. The stool can stretch and weaken the sphincter, which makes the muscles incapable of stopping normal passage. Another complication of a fecal impaction is the leakage of liquid fecal matter through the anus.
Diarrhea is the result of loose or liquid stools. These loose stools can cause an immediate need for a bowel movement. The need can be so sudden that you do not have enough time to reach a bathroom.
Damage to the sphincter will prevent the muscles from keeping the anus tightly closed. Hemorrhoids, surgery, trauma, and constipation can damage the sphincter muscles.
If the nerves that control sphincter movement are damaged, the sphincter muscles will not close properly. When this happens, you will not feel the urge to go to the bathroom. Some causes of nerve damage include trauma from giving birth, frequent constipation, stroke, diabetes, and multiple sclerosis.
External hemorrhoids can block the sphincter from closing completely. This allows loose stool and mucus to pass involuntarily.
Women can suffer from damage to the muscles and nerves in their pelvis while giving birth, but symptoms of pelvic floor dysfunction may not be immediately noticeable. They may occur years later. Complications include:
Anyone can suffer from bowel incontinence, but certain people are more likely to get it than others. You are at risk if:
Doctors perform thorough medical evaluations to diagnose bowel incontinence. You doctor will ask you about the frequency of the incontinence, when it occurs, diet, medications, and health problems. The following tests may help reach a diagnosis:
The treatment for bowel incontinence depends on the cause. Some of the treatment options include:
Foods that cause diarrhea or constipation are identified and eliminated from the diet. This can help normalize and regulate bowl movements. Your doctor many recommend an increase in fluids and fiber.
For diarrhea, antidiarrheal medications, such as loperamide, codeine, or Lomotil, may be prescribed to thicken stools. You doctor may recommend fiber supplements for constipation.
Following a bowel retraining routine can encourage normal bowel movements. Aspects of this routine may include:
You have the option of wearing specially designed undergarments for added protection. These garments are available in disposable and reusable forms, and some brands use technology that minimizes odors.
Kegel exercises strengthen the pelvic floor muscles. These exercises involve a routine of repeatedly contracting the muscles that are used when going to the bathroom. You should consult a doctor to learn the correct way to do the exercises.
Biofeedback is an alternative medical technique. With it, you learn to use your mind to control your bodily functions with the help of sensors. If you have bowel incontinence, biofeedback will help you learn how to control and strengthen your sphincter muscles. Sensors are placed in your anus and on your abdomen. Your doctor will then ask you to contract the sphincter muscles. The muscle contractions are visually displayed as a graph on a computer screen so you can observe the strength of the muscle movements. By watching the graph (the feedback), you learn how to improve rectal muscle control (the bio).
Surgical treatment is generally reserved for severe cases of bowel incontinence. There are several surgical options available.
Solesta is an injectable gel that was approved by the United States Food and Drug Administration (FDA) in 2011 for the treatment of bowel incontinence. The goal of Solesta treatment is to increase the amount of rectal tissue. The gel is injected into the anus and effectively reduces or completely treats bowel incontinence in some patients. It works by causing the growth of rectal tissue, which narrows the anal opening and helps it stay tightly closed.
Age, past trauma, and certain medical conditions can cause bowl incontinence. Unfortunately, the condition is not always preventable. The risk, however, can be reduced by maintaining regular bowel movements and by keeping the pelvic muscles strong.
