Fecal incontinence is loss of control over bowel movements. Short-term loss of bowel control can happen to anyone who has severe diarrhea. As aging occurs, the muscles and ligaments that provide both bowel and bladder control become more relaxed. They are also more apt to be affected by other conditions.
Constipation can cause fecal impaction.
Older adults are prone to constipation because of decreased muscle tone in the bowel, lack of activity, and insufficient fiber and fluid intake. The liquid remaining in the colon and small pieces of feces can seep around the impaction, causing incontinence. Uncontrolled, small, liquid stools may signal an impaction. Treatment depends on the cause. Corrective surgery may be done in some cases where there is a defect in anatomy or damage to the anus caused by injury.
