Menopause is normal for Chinese women between the ages of 40 and 60. Most menopause occurs between the ages of 45 and 55, which is a normal age, but the timing of menopause varies due to the physical and genetic factors of each woman. A small number of women may experience menopause between the ages of 40 and 45. Since menopause is too early, it may cause severe menopause and affect women’s normal life, leading to osteoporosis and vaginal dryness, so women who experience menopause during this period may consider taking estrogen and progestin preparations to replenish their body’s hormones, causing periodic vaginal bleeding like menstruation. There are also a few women who may have high estrogen and progesterone secretion from the ovaries, so they may be induced to develop fibroids. These women may experience menopause later and have more bleeding, usually over the age of 55.
