How long does menopause last for women

　　female How long does menopause last? Since the transition of gonadal function from maturation to decline occurs gradually, it is difficult to determine when menopause begins, but when the endocrine hormones of the ovaries are reduced to a certain extent, women no longer menstruate. Even though menopause Irregular menstruation often occurred in the past, but now it is generally accepted that women who stop menstruating for one year are natural menopause. Although it cannot be said that it is rare, it is rare that menstrual cramps suddenly come back one year after menopause, or even pregnancy occurs.

　　Except for some disease In addition to the need for surgery or radiotherapy to terminate ovarian function, menopausal changes generally occur before menopause; after menopause, some menopausal symptoms may continue for a period of time. In this way, from clinical It is difficult to accurately grasp the time of menopause, so we can only estimate the start time of a person's menopause from her age at menopause. Strictly speaking, the start time of menopause may vary slightly depending on region, climate, race, economy, nutrition, age at menarche, 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 women's menopause is slightly delayed, the change is not particularly big. Women experienced menopause on average at 40 to 50 years old in BC, 35 to 60 years old in medieval times, and 42 to 58 years old in Western countries today. Our country surveyed more than 130,000 women in 29 provinces and cities in 1980. The age of natural menopause is between 42 and 58 years old, with an average of 49.5 years old. Of course, there are some cases as early as 39 years old and as late as 60 years old. An earlier or later age at menopause should warrant attention until no other abnormalities are found. In fact, 95% of menopause occurs around the age of 50, and rural women are 2 years earlier on average than urban women. In 1989, the National Center for Perimenopausal Women was established by Nanjing Medical College and organized by 23 units across the country. healthy The survey cooperation group conducted a sample survey of about 2,000 women in three groups of women: medical personnel, teachers, female textile workers, and farmers. The results showed that the average age of natural menopause is 49 + 3.7 years old, with only 3.1% under 40 years old, and 1.1% over 55 years old. 》》》 Find out your personality traits from fruits

　　The factors that influence the age of menopause are analyzed: the age of menarche, the mother's age of menopause, whether she has been pregnant or not, agricultural area and city, culture and nature of work, etc. However, the proportion of menopausal symptoms does not change with the age of menopause. Some people have early menopause without discomfort, while others have experienced incompatible symptoms for a long time before complete menopause. According to the measurement of physiological indicators, menopause begins about 10 years before menopause, that is, around the age of 40. It takes about 10 years after menopause for ovarian function to completely disappear and people enter old age.
