Irritable bowel syndrome: treatment update.

Patients with irritable bowel syndrome may be classified as "psychologic reactors," "food reactors" or "mixed reactors." The management approach is tailored to the reactive pattern. Education and reassurance are paramount in the management of irritable bowel syndrome. Psychologic reactors may benefit from antidepressant therapy, psychotherapy, relaxation training and biofeedback. Eliminating offending foods from the diet may provide relief in food reactors. Regular exercise may be especially salutary in patients with constipation.
