Clinically, most women will experience a decline in ovarian function after the age of 40, and due to individual differences, menopause occurs between the ages of 45 and 55. Therefore, if a woman in her forties has menstrual disorders when other organic pathologies are ruled out, such as no uterine fibroids, no endometrial cancer, and no other pathologies, the majority of menstrual disorders are caused by the decline in ovarian function and changes in hormone levels in the clinic. If the amount is not too much, it is recommended to observe clinically; if the amount is relatively large and causes anemia clinically, it is recommended to give appropriate treatment and intervention, so as not to aggravate the anemia, which will cause great harm to the body.
