The first step is to start with lifestyle changes, less sugar, less oil and more exercise to lose weight and keep it in the normal range. If you want to lose weight, in addition to proper dieting, you should do it through aerobic exercise, i.e. heart rate of 120-140 beats/min for 40-50 minutes a day. Then, adjust reproductive hormones to restore normal ovulation. The hormones are usually adjusted by oral contraceptives such as Daimler-35 and Mafron, and if combined with hyperprolactinemia, drugs such as bromocriptine are added to lower the prolactin. In polycystic patients, LH can be very high, and when it is high, it will inhibit ovulation, so it should be lowered first. Hyperprolactinemia and hyperandrogenemia can also affect the growth and development of eggs. If prolactin and androgens are higher than normal, medication should be taken to lower them to normal. For patients with fertility requirements, after hormone normalization, stop taking oral contraceptives (if hyperprolactinemia, bromocriptine cannot be stopped and should be used according to medical advice). If there is no fertility requirement, you can control the development of the disease by taking oral contraceptives intermittently for three months, stopping for three months and eating for three months so as to ensure that menstruation comes once every 1-2 months. If you do not have a period for a long time or have a very irregular period, the endometrium is prone to lesions. The process of taking the medicine should be reviewed regularly. Last but not least, metabolic related tests such as biochemical full test and insulin resistance should also be checked and if metabolic related diseases exist they should also be treated actively to maintain a good internal environment in the body suitable for pregnancy. Regardless of fat or thin, some polycystic patients with insulin resistance and combined with hyperlipidemia should be treated actively. Because it not only affects fertility, but also is a risk factor for chronic diseases such as coronary heart disease and diabetes.
