Treatment of polycystic ovary syndrome with normal hormone levels includes lifestyle guidance, adjustment of the menstrual cycle, regulation of metabolism, and guidance for fertility. Adherence to a low-calorie, nutritionally balanced diet and moderate regular physical activity are the basis of the preferred treatment for polycystic ovary syndrome. For women with menstrual disorders during puberty, the menstrual cycle can be adjusted by cyclic use of progestins such as dydrogesterone tablets and short-acting oral contraceptives such as drospirenone ethinyl estradiol tablets. Patients with metabolic abnormalities can apply glucose-lowering drugs such as metformin; women with fertility needs should apply ovulation-promoting drugs such as letrozole. The diagnosis of polycystic ovary syndrome needs to exclude other diseases that cause hyperandrogenemia and ovulation abnormalities. If a woman has irregular menstruation, it is recommended that she consult a gynecology clinic and use medication under a doctor’s guidance. Do not use medication without authorization, and identify the cause of the disease and then treat the symptoms.
