Menopause, also known as perimenopause, mainly refers to the process of a woman's transition from the reproductive period to the non-fertile period, in which ovarian function gradually declines and the secretion of estrogen in the body decreases, thus triggering a series of physical and mental changes.
This process usually occurs between the ages of 45 and 55, but some people may enter menopause earlier or later. The appearance of menopause is mainly due to the gradual decline of ovarian function. Specifically, the ovaries are important organs in the female reproductive system, responsible for producing eggs and secreting estrogen. However, as we age, the function of the ovaries gradually declines, which leads to a decrease in the number and quality of eggs, as well as a decrease in the secretion of estrogen. When ovarian function declines to a certain level, menstruation begins to become irregular until it stops completely, which is called menopause.
In this process, due to the decline in estrogen levels, the human body will experience a series of uncomfortable symptoms, such as hot flashes, night sweats, insomnia, mood swings, etc. In addition to the decline of ovarian function, some other factors may also affect the appearance of menopause. For example, some diseases (such as autoimmune diseases), lifestyle habits (such as long-term smoking, improper diet), some unexpected situations in life, genetic factors, chemotherapy or radioactivity**, removal of the uterus or ovaries, etc., may lead to the early arrival of menopause.
In general, the appearance of menopause is caused by the decline of ovarian function and changes in hormone levels in the body, which is a normal physiological process, but the uncomfortable symptoms of menopause can be relieved with good lifestyle habits and a reasonable diet.
