The average age of menopause for women in China is around 49 years old, with most in the middle of 45-55 years old. If amenorrhea occurs before the age of 40, it is considered premature ovarian failure. Menopause is the absence of menstruation for more than a year, mainly due to the decline of ovarian function, the ability to produce estrogen and progesterone, and the inability to maintain the cyclical shedding of the endometrium, which in turn leads to the absence of menstruation. In addition to the absence of menstruation, the decrease in estrogen also causes osteoporosis and cardiovascular disease, which is clinically manifested as poor temper, poor sleep, memory loss, flushing and vaginal atrophy. This is a normal phenomenon that almost every menopausal woman has faced. Especially for postmenopausal women with vaginal bleeding, they should be alert to the possibility of endometrial lesions. If the ultrasound indicates that the endometrium is larger than 4-5mm, endometrial cancer should be excluded by active hysteroscopy or hysteroscopy. If the symptoms are too severe after menopause, you can take oral estrogen treatment as prescribed by your doctor. It is important to take menopause seriously, as it will happen to every woman, and afterwards, we need to pay more attention to our health status. It is recommended to have an annual medical checkup to detect abnormalities early. Menopause at the age of 45-55 is normal, and the exact age varies from person to person. Remember to increase calcium supplements appropriately to prevent osteoporosis, etc.
