The Year of the Rat is 4 days away, and many women are actively preparing for pregnancy to give birth to a smart rat baby in 2020. However, after months of repeatedly drinking a lot of Chinese herbs, there is no movement, and only after going to the hospital did they discover that they are suffering from polycystic ovary syndrome. What is polycystic ovary syndrome? Polycystic ovary syndrome (PCOS) is a complex endocrine and metabolic abnormality common in women of reproductive age, characterized by chronic anovulation (ovulatory dysfunction or loss) and hyperandrogenemia (excess male hormone production in women), with the main clinical manifestations being irregular menstrual cycles and infertility. There are many causes of polycystic ovary syndrome, and we are not very clear about its pathogenesis, but it is certain that obesity is an important cause of polycystic ovary syndrome, and obese patients account for 30%-60% of polycystic ovary syndrome, and these obese patients are mostly abdominal obese. So how to treat polycystic ovary syndrome? In addition to hormonal drugs and surgery, weight loss becomes an essential treatment for obese patients. Women should adopt scientific and safe methods to lose weight. They can go to the nutrition department of a hospital to consult the advice of a nutritionist, make a nutritional diet plan, monitor their body fat rate and basal metabolic rate, adjust their living and eating habits, regularize their work and rest, relax, develop exercise habits, and insist on exercising 3 to 5 times a week. In addition to possible endocrine disorders and infertility, polycystic ovary syndrome also causes the risk of type 2 diabetes and cardiovascular disease due to abnormal basal metabolism, as well as endometrial hyperplasia and endometrial cancer due to long-term anovulation. Therefore, early detection and treatment of polycystic ovary syndrome is essential. Weight loss surgery can effectively treat a variety of obesity associated diseases, such as polycystic ovary syndrome and type 2 diabetes, and is a safe and effective treatment method. Weight loss surgery can not only help women successfully cure polycystic ovary syndrome and give birth to a healthy baby, but also harvest beauty.
