Polycystic Ovary Syndrome
Polycystic ovary syndrome (PCOS) is a spectrum of disease that is characterized by menstrual irregularity due to ovulatory dysfunction and hyperandrogenism. Presenting signs and symptoms are heterogeneous and may vary over time. It is associated with an increased risk of obesity and the metabolic syndrome as well as infertility. The diagnosis of PCOS should be considered in any adolescent girl with hirsuitism, severe acne, menstrual irregularity, or obesity.
