What causes fecal impaction?

Fecal impaction is a potential complication of chronic constipation, which can be related to diet, fluid intake, medications, activity level, or conditions affecting the colon, rectum or anus.

What are the risk factors for fecal impaction?

A number of factors increase the risk of developing fecal impaction. Not all people with risk factors will get fecal impaction. Risk factors for fecal impaction include:

  • Bowel movement avoidance
  • Brain or spinal cord injury
  • Constipation
  • Diet low in fiber
  • Hirschsprung’s disease (condition present at birth in which nerves that stimulate contractions of the bowel are absent)
  • Irritable bowel syndrome (IBS; digestive discomfort that does not cause intestinal damage or serious disease)
  • Limited fluid intake
  • Medications, such as antidiarrheals, narcotics, and anticholinergics (used to treat conditions such as peptic ulcer disease, diarrhea, nausea and vomiting, motion sickness, urinary incontinence, and Parkinson’s disease)
  • Multiple sclerosis (disease that affects the brain and spinal cord causing weakness, coordination, balance difficulties, and other problems)
  • Pain in the anus or rectum, which can be due to inflammatory conditions, hemorrhoids, fissures, ulcers, or trauma
  • Parkinson’s disease (a brain disorder that impairs movement and coordination)
  • Physical inactivity

Reducing your risk of fecal impaction

You may be able to lower your risk of fecal impaction by:

  • Drinking plenty of fluids
  • Eating foods high in fiber
  • Engaging in physical activity
  • Having bowel movements when the urge is present

Once the fecal impaction is relieved, you should turn your attention to preventing future impactions. Lifestyle chang... Read more about fecal impactiontreatments
