Pre-menopausal 47-year-old women may experience menstrual disorders, phytoneurological disorders, and a variety of symptoms caused by estrogen fluctuations. After the end of the reproductive period, with the decline of ovarian function and follicle failure, a woman enters the perimenopausal stage, or pre-menopausal stage. The average perimenopausal period for Chinese women is between the ages of 45 and 50. The most typical and earliest symptom that appears during this period is menstrual changes, which may include the sudden onset of heavy vaginal bleeding after several months of menopause, or prolonged menstrual periods with an abnormal amount of menstrual flow and endless dribbling. Perimenopause is also a stage where anovulatory dysgonorrhea is likely to occur. The decline of ovarian function affects the vegetative nerves, which may lead to insomnia, excessive dreams, anxiety, irritability, irritability and even depressive tendencies, and with the fluctuation of oestrogen, there may also be hot flashes, sweating, vaginal dryness, osteoporosis, etc. The perimenopause may last for six months to six months, and may be the first symptom to appear. The perimenopausal period may last from half a year to several years, and medications can be used to relieve the symptoms appropriately according to the different symptoms of the woman, so that she can pass through this stage smoothly.
