Amenorrhea is a condition where menstruation does not occur, and it is also a necessary menstrual process for women. However, there may also be abnormal situations, which are premature amenorrhea. This is also a situation that we should pay attention to and be clear about its manifestations.
Female amenorrhea time
Female amenorrhea refers to the period when ovarian function further declines and eventually disappears. According to foreign data statistics, the risk of death for women who undergo menopause before the age of 40 is 39% higher than that of women aged 40 to 44, 60% higher than that of women aged 45 to 49, and 95% higher than that of women aged 50 to 54. Therefore, understanding the various factors that affect amenorrhea and delaying the age of amenorrhea is an issue that cannot be ignored in the healthcare work of middle-aged and elderly women.
The most important factor determining the age of menopause in women is the number of oocytes. At birth, there are approximately 1 million oocytes in each ovary, and the number of oocytes continues to decrease after birth. When the number of oocytes decreases to a critical number, amenorrhea occurs. Although the mechanism by which oocyte deceleration is controlled or regulated has not yet been fully understood, the following factors are clearly related to the timing of amenorrhea.
Research on the close correlation between age of amenorrhea and nutrition in women shows that women with long-term malnutrition, short stature, and light weight have an average age of amenorrhea of 43.6 compared to women with good nutrition, relatively high weight, and relatively heavy weight. Three years old. Smoking is an important factor in advancing the age of amenorrhea. The amphetamine in cigarettes is a lethal factor for oocytes. Animal experiments have shown that low doses of amphetamine can damage 25% of oocytes, while high doses of amphetamine can damage 98% of oocytes. According to a survey by Royal University Hospital in the UK, women who smoke and women who do not smoke enter menopause on average 54 days ago.
The average age of amenorrhea among urban women in China is 49.5 years old, while rural women are 47.5 years old. The age range for amenorrhea is between 35 and 55 years old, with 51.4 years old for American women. The age range of amenorrhea is between 48 and 55 years old. In the past century, there has been a tendency for the age of menarche to advance, but the change in the age of amenorrhea is not significant. Premature menopause or premature ovarian failure refers to menopause before the age of 40; About 1% of women experience menopause before the age of 40, and after the age of 55, it is called "delayed menopause".
