Polycystic ovary syndrome (PCOS) is a common endocrine disorder affecting women of reproductive age. It is characterized by a hormonal imbalance, which causes a variety of symptoms, including irregular menstrual cycles, acne, excessive hair growth, and infertility. Research suggests that PCOS is associated with insulin resistance, obesity, and other metabolic abnormalities. The exact cause of PCOS is unknown, but it is thought to involve genetic, environmental, and lifestyle factors. The diagnosis of PCOS is based on the presence of any two of the following criteria: irregular menstrual cycles, hyperandrogenism (excess production of androgens, such as testosterone), and/or the presence of 12 or more small cysts on the ovaries. Treatment of PCOS is tailored to the individual and may include lifestyle modifications, medications, and/or surgery. Lifestyle modifications, such as healthy eating and regular physical activity, are effective in managing PCOS symptoms and improving overall health. Medications such as birth control pills or metformin are sometimes used to regulate hormones and reduce symptoms. Surgery may be necessary in cases of severe endometrial hyperplasia or large ovarian cysts.
