Normally, women stop menstruating around the age of 50-55, but some people may stop menstruating earlier, all of which is relatively normal. Mainly due to various influences such as the usual mental stress, life stress or dietary factors and environmental factors, some women may experience various problems such as low menstrual flow and menopause at the age of about 45. Premature menopause can be regulated by taking medications that can help alleviate the problem of menopause and delay the onset of menopause. From the age of 40 onwards, the ovarian function slowly declines and the number of follicles discharged decreases significantly. This can lead to irregular menstruation or ovulation, which are normal and are signs of menopause.
