The average age of menopause in Chinese women is 50 years old, but in fact, many women start to enter menopause after the age of 40 when the function of the ovaries is not good, and many symptoms appear, as follows: 1. Changes in menstruation: for example, the menstrual cycle becomes shorter and shorter or menstruation sometimes comes twice a month, sometimes once every 2 months. The onset of menopause is defined medically as a variation in the length of the menstrual cycle of ≥7 days that recurs within 10 menstrual cycles. The length variation means that if the current period is 30 days old, the next one will be 20 days old. A variation in the length of the menstrual cycle of more than 7 days indicates the onset of menopause. 2. Many other problems may occur before menopause, such as headache, back pain, breast distention, abdominal distention, constipation, edema of the extremities, weight gain, and loss of motor coordination. 3. There are also some mental symptoms, such as irritability, anxiety, depression emotional instability, fatigue, and changes in diet, sleep, and sexual desire.
