Polycystic ovary syndrome (PCOS) is a common endocrine disorder that significantly affects metabolism. Women with PCOS often exhibit insulin resistance, leading to hyperinsulinemia. This condition can exacerbate hyperandrogenism, contributing to symptoms such as hirsutism and acne. Additionally, PCOS is associated with an increased risk of obesity, type 2 diabetes, and cardiovascular diseases due to altered lipid metabolism and glucose intolerance.
