Managing the premenstrual syndrome.
The definition, classification, proposed etiologies, diagnosis, and treatment of the premenstrual syndrome (PMS) are discussed, and guidelines for the clinical management of PMS are presented. PMS encompasses a cluster of physical and psychosocial symptoms that recur during each menstrual cycle. Proposed etiologies for the syndrome include a hormonal imbalance between estrogen and progesterone, pyridoxine hydrochloride deficiency, hypoglycemia, excess prostaglandin production, and increased aldosterone concentrations in the luteal phase of the menstrual cycle. Diagnosis of PMS is usually based on a patient's history of recurrent symptoms accompanied by a seven-day, symptom-free period in the first half of the menstrual cycle. Management of PMS is complicated by the difficulty in diagnosing the syndrome and its unclear etiology. If possible, conservative nonpharmacologic treatment should be tried initially; suggested measures include modifications in diet, exercise, substance use, stress factors, rest patterns, and social support. Pharmacologic treatment should be considered when conservative therapies are ineffective or when PMS symptoms are more severe. Although most therapies are empirical, treatment with progesterone, pyridoxine, bromocriptine, or diuretics might prove beneficial. Once the decision is made to initiate drug therapy, the treatment regimen should be individualized and based on the patient's PMS symptom complex. The clinical management of PMS is complicated by the lack of well-designed clinical investigations of proposed treatments. Future research should be directed toward evaluating the efficacy of proposed therapeutic regimens.
