If you experience an increase in menstrual flow at the age of 45, this is also clinically abnormal. After women enter the age of 40, ovarian function gradually begins to decline, and because the hormone levels in the body have changed significantly, some women tend to experience changes in menstrual flow at the age of 45, with some experiencing an increase in menstrual flow, others experiencing a decrease in menstrual flow, and others experiencing a disruption of the menstrual cycle, mainly due to changes in hormone levels. It is also recommended to exclude that the increased menstrual flow is caused by endometrial polyps, endometrial inflammation, submucosal fibroids or large interstitial fibroids. If it is accompanied by more severe dysmenorrhea, the possibility of adenomyosis should be ruled out, and appropriate treatment should be given according to the results of all tests.
