Endocrine abnormalities in polycystic ovary syndrome (PCOS) are mainly manifested in two ways: 1) high androgens and ovulation disorders leading to menstrual disorders and infertility. 2. Insulin resistance leads to obesity and increased chance of diabetes. These two aspects are interrelated and mutually reinforcing. Doctors usually give oral short-acting contraceptives such as Daimler-35 to improve hyperandrogenism and ovulation disorders. What advice do doctors give in cases where insulin resistance leads to obesity and an increased chance of diabetes? I. Dietary adjustment Dietary adjustment is an important adjunctive treatment for PCOS, controlling the total calorie intake and choosing foods carefully. 1, daily supplementation of 500 to 1500 mg (mg) of calcium tablets and a multivitamin containing 400 micrograms (mcg) of folic acid. 2. Daily hydration should be up to 8 glasses of water. 3.Control blood lipids. To avoid blood lipid abnormalities, eat less food containing saturated fatty acids and hydrogenated fatty acids, such as pork, beef and lamb, fatty meat, various poultry and livestock skins, cream, artificial cream, full-fat milk, fried food, Chinese and Western-style cakes and pastries; 4. Choose high-quality protein. Fish, egg whites, beans, nuts are better sources of protein. Second, moderate exercise, scientific weight loss increase exercise to reduce weight, so that weight can be reduced by about 2 kg per month at a safe rate, correct the endocrine metabolic disorders exacerbated by obesity, reduce insulin resistance and hyperinsulinemia. Weight reduction can make some obese PCOS patients resume ovulation and prevent the occurrence of type 2 diabetes and cardiovascular disease. Third, metformin metformin treatment can effectively reduce body weight, improve insulin sensitivity, lower insulin levels, reduce hair and even restore menstruation (25%) with ovulation. Polycystic ovary syndrome is a syndrome of endocrine and metabolic disorders that requires lifestyle modification, including diet and exercise, along with complementary medications.
