Xiao Fei is 15 years old and has just been admitted to a major high school with excellent academic performance. The original tension before the midterm exams was completely relaxed by the now slightly more relaxed high school life. But recently, Xiao Li realized that she hadn’t had her period for nearly six months. Since the age of 12 to the first menstruation, small Fei every 2 months or so to get a period, in addition to the face occasionally a few small acne and did not feel different, so do not think. The first time I saw a woman, I was a little panicky, and I was getting fatter and fatter, my belly became more and more obvious, my limbs and upper lip also grew deeper and thicker small hairs, the small pimples on my face stubbornly did not recede, but also gradually more trend, looking at the close friends around each smooth and delicate skin, slim and attractive body, Xiao Fei secretly saddened, and wondered: “I, or a girl? The first thing you need to do is to get a good idea of what you’re looking for. The first time I saw a girl, I was a girl. Finally, Xiaofei accompanied by her mother to the hospital, after examination, the doctor diagnosed Xiaofei with polycystic ovary syndrome, given oral contraceptives Daying-35 three courses, each course of treatment after the onset of menstruation, but after stopping the drug, menstruation is not again …… “aunt The “aunt” always comes late In the clinic, we often encounter adolescent girls led by their parents to the gynecology clinic, usually they visit the reason, some are menstrual disorders, but more are amenorrhea like Faye. As we know, the sexual organs of girls, including ovaries, uterus and vagina, are basically in a static state and small in size before puberty. After puberty, under the influence of endocrine, the morphology, function and secondary sexual characteristics of female reproductive organs develop rapidly. 8~10 years old, the development of ovaries rises rapidly; between 10~18 years old, the development of uterus and vagina also accelerates linearly. With the morphological development of the sex organs, the functional development also develops and matures rapidly, and the first menstruation appears, which generally occurs in the later part of the year when the height growth is the fastest. According to the relevant statistics in China, the first menstruation of young girls is mostly at the age of 12 to 16, influenced by genetics, nutrition, climate a variety of factors, some girls earlier, some later. Generally speaking, the first menstruation of Han Chinese girls earlier than ethnic minorities, towns earlier than the countryside, coastal areas earlier than the northwest, southwest and other remote areas, large cities earlier than small towns. The first menstruation of teenage girls is simply a sign that the reproductive system is beginning to work, but its function is not yet mature, so the menstrual cycle is often less regular for a period of time after the first menstruation. A normal and stable menstrual cycle is 28-30 days. However, due to the influence of race, heredity and individual differences between people, and, the same person may be a week earlier or later due to changes in the internal and external environment, it is generally normal in the range of 21 to 35 days. According to the survey, from menarche to the second menstrual period, most people are in more than six months, some up to eight or nine months. Therefore, irregular menstrual cycle after menarche, a few girls with increased body hair, facial acne, etc., this is mostly normal, usually within two years will gradually become regular. The phenomenon of irregular menstrual cycle after menarche should be fully understood, do not think that it is a disease and take drugs indiscriminately, so as not to affect health; but if the menstruation is still abnormal for more than 2 years, it should cause the young girls themselves and their parents to pay great attention, especially to be alert to the possibility of polycystic ovary syndrome. The incidence of polycystic ovary syndrome is a common endocrine and metabolic disorder in women of childbearing age, mostly after the onset of menstruation. The cause of this disease is still unclear, and it is speculated that it may be a polygenic genetic disease. There is a certain degree of family aggregation in this group of patients, with many patients’ fathers having hirsutism, acne, seborrheic dermatitis and early baldness, and their mothers and sisters having scanty menstruation and infertility. However, the occurrence of polycystic ovary syndrome during puberty is closely related to the physiological changes during puberty, especially hormonal changes, hyperdevelopment and insulin resistance. However, when there is an endocrine disorder, excessively high androgens will not only lead to acne, excessive lip hair, armpit hair and pubic hair, but also to menstrual disorders. In addition, a significant proportion of adolescent polycystic ovary syndrome is related to genetics. Acquired environmental factors, such as academic stress, emotional problems, and overnutrition, also tend to lead to ovarian dysfunction during adolescence. In addition to menstrual irregularities, patients with polycystic ovary syndrome have a very characteristic clinical presentation and endocrine profile. In addition, most patients are hairy, and some have acne and seborrheic dermatitis. In addition, most patients are hairy and some have acne and seborrheic dermatitis. Ultrasound can reveal multiple follicles on the ovaries, but no ovulation, thus affecting reproductive health and leading to infertility. Therefore, polycystic ovary syndrome is a disease that seriously affects women’s health throughout their lives. Adolescent girls should be particularly alert to polycystic ovary syndrome and seek early medical treatment if they have the following conditions: 1. hirsutism or acne with irregular menstruation or obesity; 2. severe acne that requires treatment in early adolescence or for which conventional methods are ineffective; 3. excessive weight gain with acanthosis nigricans; 4. metabolic syndrome (central obesity combined with elevated blood pressure, blood glucose, triglycerides, and/or lower HDL), or a family history of type 2 diabetes. It is said that “prevention is better than cure”, so it is recommended that prevention of polycystic ovary syndrome must be started from adolescence, because most polycystic ovary syndrome in adolescent girls is caused by malfunction of hypothalamus and pituitary gland. If you are unable to sleep, you can do moderate exercise two hours after meals or do abdominal massage before bed to promote sleep.
