Xiao Li has been having irregular periods since she started high school. At first, she didn’t think it was because she was under too much pressure from her studies, but she thought it would get better after she went to college. After going to college, her period did not improve, her face acne more and more, the upper lip, cheeks and jaw, and other places slowly grow a noticeable beard, the body has also become a lot of fat, menstruation does not come others do not know,? This acne, beard and obesity for girls is a big fat thing, seriously troubled Xiaoli, repeatedly seeking medical advice did not improve. The company’s main goal is to provide a comprehensive range of products and services to the public. The incidence of polycystic ovary syndrome is gradually increasing in recent years, mostly in adolescent and reproductive age women, the incidence is about 5-10%. Clinical history shows that some adolescent girls have abnormal menstruation since menarche and are unable to form normal cycles after 1-2 years; some girls have normal menstruation and later develop the disease due to various reasons, such as pressure from midterm and entrance exams, change in diet structure after going abroad, and significant weight gain. The pathogenic factors may be related to genetic factors, environmental factors, including high androgens, application of anti-epileptic G drugs, geography, nutrition and lifestyle, all of which may be risk factors, predisposing factors and high-risk factors for PCOS. In women with polycystic ovary syndrome, many small follicles that have developed but cannot mature to ovulate gather on the surface of the ovaries due to the long-term non-ovulation of the menstrual cycle, so pelvic ultrasound, especially transvaginal ultrasound, will often reveal enlarged ovaries bilaterally, with more than 12 small follicles less than 10mm in diameter in each ovary. “polycystic ovary syndrome”. In turn, this change is there caused by abnormalities or dysregulation of endocrine in the female body. Examination may show hyperandrogenism, hyperluteinizing hormone or elevated luteinizing hormone to follicular estrogen ratio, hyperinsulinemia, etc. The onset, progression and regression of PCOS affects women throughout their lives. Menstrual disorders, hirsutism, acne, and obesity are common symptoms of polycystic ovary syndrome. Women of reproductive age with polycystic ovary syndrome also have combined infertility. In addition, the current medical concept of treatment for PCOS is no longer limited to ovulation and pregnancy, but the health problems associated with the long-term complications of PCOS (diabetes, hypertension, cardiovascular disease, endometrial cancer, etc.) are receiving more and more attention. Clinical studies have shown that women with PCOS are 5-10 times more likely than normal to have impaired glucose tolerance, and that the age of onset shifts forward (around 30-40 years of age), about 50% of young women with PCOS have abnormal lipid metabolism, and the probability of postmenopausal myocardial infarction in women with PCOS is significantly higher, about 7.1 times that of non-PCOS women. Many countries and regions have actively explored the problems of hyperinsulinemia, insulin resistance (IR), hyperandrogenemia, infertility and various metabolic complications in women with PCOS, and have conducted clinical trials at different levels, including obstetrics and gynecology, endocrinology, molecular biology and genetics. Many fields have been investigated. The aim is to provide a reference for the therapeutic research of PCOS.
