Depending on the cause, some types of fecal incontinence may be prevented. Some prevention techniques include:

• Reducing constipation. Fecal incontinence due to chronic constipation can be improved or eliminated by treating the constipation. Tips include getting more exercise, eating high-fiber foods and drinking plenty of fluids. Taking fiber supplements can also reduce constipation.
  
  
• Controlling or preventing diarrhea. Treating the cause of diarrhea, such as an intestinal infection, may prevent fecal incontinence. Some people can prevent diarrhea by avoiding foods that contain sugars such as lactose (from milk), fructose (from fruit) and sorbitol (from berries and other fruits).
  
  
• Avoiding straining. Straining during bowel movements may weaken anal sphincter muscles which can lead to fecal incontinence.

People prone to diarrhea or constipation should see a physician to determine if an underlying disorder is causing these symptoms. Early detection and treatment of any such problems can prevent constipation or diarrhea that may lead to fecal incontinence.
