Hi.. Thanks for contacting practo for health query.This is Dr.Shanmugavadivu answering your question. PCOD is polycystic ovarian disease means your ovaries are cystic. Every month for a lady a follicle grows , breaks and release a ovum .In PCOS the follicle does not grow to maturity and remains as cyst which will result in not getting periods right time,obesity,infertilty. Kindly meet a physician or gynaecologist who will treat you if necessary. From your side maintain your weight in normal BMI range ,do exercise and eat balanced low calorie diet.
