PCOS often has its origins in adolescence and can be triggered by physiological changes during puberty in genetically predisposed individuals. Early identification and treatment is important to prevent long-term health consequences. Lifestyle modifications including diet and exercise are the primary treatment approach for overweight adolescents with PCOS. Oral contraceptives are also used to treat menstrual irregularities and hirsutism, while metformin may be added to help with hyperinsulinemia and improve ovulation. Counseling adolescents on PCOS aims to help manage symptoms and reduce risks of future infertility or metabolic disorders.
