Three major factors leading to amenorrhea in women

　　1. Dieting to lose weight and hormone reduction

　　Ms. Lin is 26 years old and unmarried. In order to be slim, she started dieting for three months.“ amenorrhea ”. After taking traditional Chinese medicine for more than a month, I still haven’t had my period. to local Hospital I did a color ultrasound and said Uterus Everything is normal, but for some reason I still haven’t had my period.

　　Gynecology Experts say that missing menstruation for three months cannot be medically diagnosed as "amenorrhea." The most common reason for this kind of short-term amenorrhea is weight loss and dieting. Cases like Ms. Lin's case of amenorrhea due to dieting and weight loss are not uncommon in gynecological clinics.

　　During dieting, while suppressing appetite, the cerebral cortex also reduces the secretion of luteinizing hormone and follicle-stimulating hormone from the pituitary gland. These hormones play an important role in menstruation. Once they are reduced, menstruation will not come. So, some female After a period of weight loss, menstruation decreases and the menstrual cycle lengthens first (for example, menstruation lasts from 28 days to 35 days), and then amenorrhea occurs.

　　About 50% of patients with this kind of amenorrhea can stop losing weight, return to a normal weight, and have normal hormone secretion to have menstruation come again. In addition, 25% of patients can be cured with ovulation induction drugs. However, there are still a few cases that are difficult to cure, which are often caused by prolonged amenorrhea.

　　2. Mood swings, cold and cold

　　Women’s menstruation is regulated by the hypothalamus-pituitary-ovarian gonadal axis, so mood swings and changes in the hot and cold environment can be fed back to this gonadal axis, leading to Irregular menstruation . Shi Wenjing said that amenorrhea caused by psychological and emotional factors is most easily ignored. Many women do not know that excessive mental stress, anger, depression, and anxiety may cause amenorrhea.

　　Medical research shows that abnormal mood swings will inevitably interfere with the central nervous system nerve The normal work of the ovary affects the regulation of ovarian function that determines menstrual changes, causing menstrual period disorders and leading to amenorrhea. Psychological treatment is necessary for this kind of amenorrhea. Counseling and venting negative emotions is the basic method. Generally, there is no need for medical treatment. For example, some women are under too much work pressure. As long as they go on vacation and rest for a period of time, menstruation can quickly return to normal.

　　Gynecological experts remind that in summer, even if women wear too thin clothes in air-conditioned rooms, catching cold will lead to oligomenorrhea or even amenorrhea. Traditional Chinese medicine says, "Warmth leads to relaxation, cold leads to coagulation." Women who are stimulated by cold during menstruation will cause excessive contraction of blood vessels in the pelvic cavity, which can cause oligomenorrhea or even amenorrhea. Therefore, it can be said that women like warmth and are afraid of cold, so they need to protect themselves from overwork, especially during menstruation.

　　3. Vigorous exercise, fat reduction

　　Ms. Li has suffered from menstrual irregularities for the past six months, and recently developed amenorrhea. She was uneasy and worried about herself healthy Something went wrong. After careful consultation, the doctor learned that Ms. Li was a ballet dancer who had been participating in intense rehearsals and performances for the past six months. The menstrual disorder was probably caused by endocrine disorders caused by intense training, fast-paced life, especially the high excitement during the performance stage, resulting in temporary amenorrhea.

　　Gynecological experts say that this condition is medically called "exercise-induced amenorrhea" and is common in female athletes. Due to long-term participation in strenuous sports training or competition activities, the body is under strong stress and the secretion of gonadotropin decreases, which causes abnormal hypothalamus-pituitary function, causing delayed menstruation or temporary menstrual disorder in normal menstruation, leading to amenorrhea. According to statistics, the incidence of amenorrhea among long-distance runners can be as high as 59%, and that among ballet dancers is as high as 79%.

　　Exercise-induced amenorrhea is not necessarily solely due to the body's stress response, but is also related to the reduction of body fat content and insufficient protein content in the diet. Amenorrhea will also occur when the body weight is reduced by 10%-15% and the body fat content is lost by 30%. Generally speaking, when the amount of exercise is reduced, the stress on the human body gradually reduces or disappears, the fat ratio increases, and the menstrual cycle can gradually resume.
