Problems in Family Practice A Clinical Approach to the Somatizing Patient Robert C. Smith, MD East Lansing, Michigan Patients with chronic, unexplained physical complaints are evaluated diagnostically in two steps in primary care: (1) brief consideration of three specific, but rare, disorders (somatic delusion, conversion, and malingering); and (2) extensive consideration of the remaining three common but overlapping disorders (somatization disorder, hypochondriasis, and psychogenic pain). Because of frequent confusion in differ entiating among the common somatizing disorders and be cause the treatment is similar for all, the family physician can be content with the general designation of “common somati zation syndrome” when unable to distinguish among them. This diagnosis can be easily established by a good history and physical examination. Psychiatric referral is required for the rare somatizing disor ders. The primary physician can manage the majority of the common somatizing patients by observing the following prin ciples: develop a good physician-patient relationship, apply techniques of behavior modification, engage the patient at the somatic level but extend it to include associated life stresses, strategically use symptomatic measures, treat depression with full doses of antidepressants, and accept the importance of ongoing contact with the patient irrespective of symptoms. When these therapeutic principles are employed, decreased morbidity, medical utilization, and cost can be expected to follow. Because of their chronic, unexplained physical tion’s Diagnostic and Statistical Manual of Men symptoms, somatizing patients have long posed tal Disorders (DSM-III), the majority of disorders diagnostic and therapeutic challenges to phy in this group are defined as somatoform disor sicians.1"3 In the American Psychiatric Associa- ders,4 the four specific disorders being conver sion, somatization disorder, hypochondriasis, From the Departments of Medicine and Psychiatry, Uni and psychogenic pain.

These patients typically present with multiple and nonspecific somatic complaints of virtually any type including pain.19 Their style of presentation, however, may be very specific; in contrast to Briquet's syndrome, the patient’s concern is char The Common Somatizing Disorders acteristically obsessive.
