Polycystic Ovary Syndrome (PCOS) is a hormonal disorder affecting women of reproductive age, characterized by irregular menstrual cycles, ovarian cysts, and elevated androgen levels. It can lead to infertility, insulin resistance, and increased risks for type 2 diabetes and heart disease. Lifestyle changes, such as diet and exercise, combined with medications like birth control or metformin, can help manage symptoms. Early intervention improves long-term health outcomes and fertility.
