title: Polycystic ovary syndrome: a review for primary providers.
abstract: PCOS is a metabolic syndrome that exists throughout the world with much clinical heterogeneity. PCOS is now appreciated as encompassing two interrelated metabolic phenomena--insulin resistance and hyperandrogenism. Patients present with oligo-amenorrhea and clinical hyperandrogenism, and the diagnosis is based on clinical grounds with few laboratory tests necessary. Because patients are at higher than normal risk for diabetes, glucose intolerance, and hyperlipidemia, and perhaps at higher risk for coronary heart disease, newly diagnosed patients with PCOS should be evaluated for glucose intolerance and hyperlipidemia. The cornerstone of therapy today includes weight management, and further therapeutic intervention is focused on reproductive and cardiovascular health and treatment of insulin resistance. Clinical case continued The 17-year-old mentioned in the beginning of this article probably does have PCOS. She fits the clinical criteria: oligo-ovulation and hyper-androgenism (the acne and hirsutism). In addition, she is obese, which is also associated with PCOS. Her TSH and prolactin were normal, and as her presentation was not suggestive of an adrenal tumor or congenital adrenal hyperplasia (she had mild hirsutism, and those diagnoses are associated with more severe hyperandrogenism), no further laboratory evaluation was deemed necessary. Once the diagnosis was made, she was screened for lipid abnormalities and for glucose intolerance. Her LDL was 150, HDL 35; oral glucose tolerance test (OGTT) was normal. A pregnancy test was negative, and she was started on OCPs. Devoting herself to exercise and dietary change, she lost 10 pounds in her first 3 months after diagnosis. Her hirsutism and acne have improved with the OCPs and weight loss, and her menses are regular. She has elected to defer oral insulin sensitizers until her weight loss has stabilized. Findings PCOS is common in reproductive-aged women. Diagnosis is clinical and is supported by lab findings; there is significant clinical heterogeneity. Insulin resistance is likely central to the pathophysiology along with androgen excess. Health implications include infertility, diabetes, endometrial cancer, hyperlipidemia, and possibly coronary heart disease. Treatment is evolving and includes weight loss, OCPs, and insulin sensitizers.
