Idiopathic Constipation and Fecal Incontinence.

Patients with constipation or fecal incontinence have great potential for remediation. Both disorders warrant a thorough diagnostic evaluation to search for remediable causes, especially to identify defecation disorders. Constipation should be treated by relieving any impactions and then starting a course of fiber supplementation of at least 20 g per day. If not successful, other agents such as lactulose, polyethylene glycol solutions, or stimulants can be added. Biofeedback may be very helpful. If all else fails, several surgical procedures are available. Fecal incontinence should be treated by fiber supplements, encouragement of regularity, and enemas as needed. Kegel exercises and biofeedback are often helpful, but surgery may be needed and is most effective in recent onset or traumatically induced incontinence.
