The prevalence of cystic ovary syndrome (PCOS) is as high as 5-10%. The main effects of the disease include: menstruation and reproductive function. Glucose metabolism and lipid metabolism. PCOS is a chronic disease that affects women’s health almost throughout their lives and is not curable but can be managed. I. Hazards of polycystic ovary syndrome Recent hazards: including menstrual disorders, infertility, acne, hirsutism, obesity, etc. Most people know the disease only in the near future and think that adjusting menstruation and curing infertility is the ultimate goal, but you are wrong! Obstetric harms: 2 times more miscarriages, 3 to 4 times more incidence of gestational diabetes and gestational hypertension. One of my studies found that the prevalence of gestational diabetes in PCOS assisted conception patients was about 40%, so I’m not really scaring you! Long-term risks include increased incidence of endometrial cancer, diabetes, metabolic syndrome, cardiovascular disease, etc. These are the invisible killers lurking in the body of PCOS patients, and they are very insidious and have very serious consequences! Unknowingly you will be shot! Second, the need for long-term management Because of the far-reaching impact of the disease on women’s health, the disease requires long-term management. The immediate goal of long-term management is to adjust the menstrual cycle, treat hirsutism and acne, control weight, and assist fertility; the long-term goal is to protect the endometrium to prevent endometrial cancer, prevent diabetes, cardiovascular disease, etc. Misconceptions in the diagnosis and treatment of polycystic ovary syndrome Myth 1: Only the sex hormones are tested, but not the changes in metabolic indicators; Myth 2: Only menstruation is regulated, and once diagnosed, it is treated with Daing 35; Myth 3: As long as the infertility is caused by PCOS, as soon as diagnosed, ovulation is promoted, regardless of the presence of metabolic abnormalities, regardless of the high level of androgens, regardless of the impact on obstetric complications; Myth 4 Long-term management of polycystic ovary syndrome Long-term management of PCOS includes: regular testing, development of a reasonable treatment plan, and timely adjustment of the treatment plan according to the situation, and long-term management needs to last a lifetime. Regular testing 1. What to test: testing indicators include hormones (FSH, LH, PRL, T, E2, SHBG, etc.), glucose metabolism (OGTT, INS release test), lipid metabolism, changes in liver and kidney function, etc.; 2. When to test: testing before treatment is aimed at developing individualized treatment plans; testing once every 3-6 months during treatment to understand the effect of treatment; testing before pregnancy to determine the presence of Pre-conception testing to determine the presence of obstetric risks and the need for pre-conception treatment. Individualized treatment plan: Since PCOS patients are highly heterogeneous and each patient has different performance, individualized treatment is needed according to each individual’s situation and requirements. Lifestyle modification: 1. Exercise, diet modification, stress reduction and regular life help restore ovulation and menstruation and prevent cancer, metabolic disorders and other long-term complications; 2. Androgen lowering: oral contraceptives (OC) are preferred, as well as spironolactone and dexamethasone; 3. Progestin: used for those with less severe hyperandrogenic symptoms and regular withdrawal to protect the endometrium from cancer; 4. Insulin resistance Treatment: Metformin is preferred. 5, infertile patients: ovulation promotion for pregnancy is adapted to patients with pregnancy requirements to adjust the treatment plan in due course: PCOS patients must be treated with consideration of different age stages, different requirements, different disease stages and other issues for the adjustment of the treatment plan. 6. Adolescent patients should pay attention to their specific stage of physiological Kaohsiung unless androgens are particularly high and excessive intervention is not recommended; 7. Those without fertility requirements should be regularly tested for efficacy during treatment to determine whether to stop, continue treatment, or adjust the regimen; 8. Women still need to pay attention to the risk of metabolic diseases and should be tested regularly and treated timely.
