Health tips: menopause troubles some female friends, so how long does menopause last? Because the function of gonad changes from maturity to decline gradually, it is difficult to be sure when menopause begins. However, when the endocrine hormone of ovary is reduced to a certain extent, women will stop menstruation. Even before menopause often have irregular menstruation performance, now it is recognized that women naturally stop menstruation for one year, that is natural menopause. One year after menopause, there is a sudden surge, and even pregnancy, although it can't be said that there is only one.
In addition to surgery or radiotherapy to terminate ovarian function due to the needs of some diseases, menopause changes usually occur before menopause; after menopause, some menopausal symptoms may continue for a period of time. In this way, it is difficult to accurately grasp clinically, so we can only estimate the onset time of menopause from a person's menopause age. Strictly speaking, the onset time of menopause varies slightly depending on the region, climate, race, economy, nutrition, menarche age, marriage and childbirth, and contraceptive methods.
On the other hand, it can be seen from some records in western history that although the age of menopause is slightly delayed, the change is not particularly large. The average age of women in BC was 40-50 years old, 35-60 years old in middle ancient times, and 42-58 years old in western countries at present. In 1980, more than 130000 women from 29 provinces and cities were investigated. The age of natural menopause was between 42 and 58 years old, with an average of 49.5 years old. Of course, some of them were as early as 39 years old and later as 60 years old. Attention should be paid to the age of early or late menopause until no other abnormality is found. In fact, 95% of postmenopausal women are around 50 years old, and rural women are on average two years earlier than urban women. In 1989, Nanjing Medical College organized the national perimenopausal women's health survey cooperation group, which was established by 23 units in China. The results showed that the average age of natural menopause was 49 + 3.7 years old, only 3.1% of them were under 40 years old, and 1.1% were over 55 years old.
The influencing factors of menopause age are as follows: menarche age, mother's menopause age, pregnancy or childbirth, agricultural area and city, culture and work nature. However, the proportion of menopausal symptoms does not change with the age of menopause. Some people menopause early without discomfort, while others have symptoms of maladjustment, and complete menopause occurs after quite a period. According to the determination of physiological indicators, menopause begins about 10 years before menopause, that is, about 40 years old; about 10 years after menopause, ovarian function completely disappears, and people enter the old age.
