This document discusses polycystic ovarian syndrome (PCOS), a common endocrine disorder that affects around 5-10% of women. PCOS is characterized by excess androgen production in the ovaries which interferes with reproductive, endocrine, and metabolic functions. Common symptoms include irregular or absent periods, weight gain, acne, and excess hair growth. Women with PCOS also have an increased risk of diabetes, heart disease, and infertility. While the exact causes are unclear, lifestyle and genetic factors likely play a role. Treatment focuses on lifestyle changes like diet and exercise as well as medication to manage symptoms and health risks.
