The normal range of menopause is around 45-55 years old, and it is normal for menopause to occur during this period. Menopause is a normal physiological phenomenon in women. It is the gradual decline of ovarian function that leads to a decrease in the secretion of estrogen, progesterone and other related hormones in the body, resulting in a series of changes such as menstrual disorders. Menopause is generally considered to be the absence of menstruation for more than six months. The most obvious symptom is the change in menstruation, with longer and less frequent menstrual periods. Some women may experience a sudden increase or decrease in the amount of menstrual flow or incomplete menstruation. They may also experience emotional instability, such as irritability, poor sleep, or even insomnia. In addition, many women may experience hot flashes, but these symptoms may ease after menopause is complete.
