Biofeedback for Chronic Constipation?

Robert W. Griffith, MD

Chronic constipation is a problem for many people, and treatment is often unsatisfactory. About 2% of the US population suffers from chronic constipation, and many more take remedies to help them keep 'regular'. One of the more successful medications in use, up to a few weeks ago, was tegaserod (Zelnorm®), but it has recently been withdrawn from the market because of an unacceptable level of cardiac side effects.

Just in time comes a new approach - biofeedback. Researchers in Iowa City have conducted a study and reported their findings in the journal Clinical Gastroeneterology and Hepatology. Using simple instruments to measure pressure in the rectum, the scientists compared the results of treatment using expert training in the 'manipulation' of the results from these instruments in one group of patients, with 'sham feedback' (inappropriate or no training) in another group, and standard therapy (diet, exercise, laxatives) in a third group.

A total of 77 subjects (77 were women) were studied. After 3 months of treatment those in the biofeedback group were significantly more likely to produce satisfactory pressure readings than the sham feedback group, and the biofeedback subjects had more complete spontaneous bowel movements than those in the other two groups. The authors conclude that biofeedback is the preferred treatment for patients with chronic constipation, especially those who have failed standard therapy.

This approach will not suit everyone. But, with the difficulties surrounding Zelnorm, it may become a more widely used option. If the patient can find a center that offers it . . .
