PCOS is very common in India, affecting up to 2 in 5 adolescents and 1 in 5 adult women. Factors contributing to its high prevalence in India include urbanization, earlier menarche, genetic predisposition, and early malnutrition. Common symptoms include hirsutism in 44% of cases, acne in 20%, and glucose intolerance in 16.3% of women. PCOS is associated with increased risks of depression, diabetes, cardiovascular disease, non-alcoholic steatohepatitis, and obstructive sleep apnea. Diagnosis requires one biochemical and one clinical criterion. Lifestyle modifications like diet and exercise are the first line treatment, while bariatric surgery may be recommended for severe obesity.
