Polycystic usually refers to polycystic ovary syndrome, for which there is no clear cure and symptomatic treatment is the mainstay. For obesity caused by polycystic ovary syndrome, it can be treated by lifestyle intervention, drugs and other ways to reduce fat. 1. Lifestyle intervention: Reduce calorie intake, eat a balanced diet, and try to eat low-fat, low-sugar and high-fiber foods in daily life. Appropriate physical exercise, a combination of anaerobic and aerobic exercise, can effectively promote metabolism and fat burning to avoid fat accumulation. Reduce mental stress, quit smoking and limit alcohol. 2. Medication: Obese patients who are not satisfied with the treatment effect of lifestyle intervention can choose orlistat oral treatment to reduce fat absorption. When combined with metabolic abnormalities such as hyperinsulinemia and diabetes, symptomatic treatment with drugs such as metformin and pioglitazone is needed. Obese patients with polycystic ovary syndrome are advised to seek timely medical treatment under the guidance of a doctor to avoid adverse reactions to private medication.
