Before menopause, due to the decline of estrogen and the decline of ovarian function, the endometrium does not have sufficient amount of estrogen to repair, so it manifests as an unusually heavy menstrual flow. This is a symptom unique to premenopause, and if it does not cause anemia, there is no need to be nervous. If you are already experiencing heavy menstrual flow causing anemia, it is recommended that you go to the hospital for a checkup to rule out other diseases causing increased menstrual flow and to give appropriate treatment and intervention. In case of heavy menstruation before menopause, it is important to give adjustments from the diet, such as drinking more fresh soy milk and, if there are no fibroids, drinking royal jelly, both of which can help reduce the menstrual flow. In addition, it will be good for the body.
