Evaluating and managing premenstrual syndrome.

Abstract

Premenstrual syndrome (PMS), a common disorder in women, refers to physical and/or mood symptoms that appear predictably during the latter half of the menstrual cycle, last until menses begin, and are absent during the early part of the menstrual cycle. A diagnosis of PMS requires that the symptoms be severe enough to affect a woman's ability to function at home or in the workplace or in her relationships with others. Diagnostic assessment entails a thorough medical and psychiatric history and prospective daily ratings. Disorders such as major depression, anxiety, hypothyroidism, and diabetes must be excluded before a diagnosis of PMS can be considered. Treatment strategies include either eliminating the hormonal cycle associated with ovulation or treating the symptom(s) causing the most distress to the patient. Medical therapies are available for both treatment approaches but should be initiated only after behavioral measures have failed; the physician must also carefully weigh the severity of symptoms against the potential for adverse effects of treatment.
