Polycystic ovary syndrome belongs to reproductive endocrine metabolic diseases, its pathogenesis may be related to genetics and metabolism, and generally cannot be cured by itself. Its clinical manifestations are mostly irregular menstruation, scanty menstruation or even amenorrhea, so clinical intervention must be given, otherwise once amenorrhea occurs, the endometrium will keep proliferating under the effect of estrogen, which will not only lead to infertility, but also endometrial cancer, diabetes and cardiovascular disease in the distant future in serious cases. Once irregular menstruation, scanty menstruation, hirsutism, acne, and long-term infertility in women of reproductive age occur, they need to be alert to the possibility of polycystic ovary syndrome and visit the hospital in time. If diagnosed, doctors will take different treatment measures according to the patient’s age, treatment needs and clinical manifestations, including lifestyle adjustment and oral medication, such as controlling diet, proper exercise, changing bad habits, taking oral hormonal drugs, etc., to relieve symptoms, solve fertility problems, maintain health and improve quality of life.
