Having a total menstrual flow of more than 80 ml is clinically diagnosed as excessive menstruation. Menorrhagia is definitely not normal and is often caused by the following clinical reasons: 1) submucosal fibroids or large interstitial fibroids, which can increase the menstrual flow and cause blood clots; 2) clinically, it is caused by functional bleeding, which can lead to a large amount of menstrual blood during puberty due to estrogen deficiency, and needs to be treated clinically with Glaxo. At the time of menopause, due to the disorder of hormone levels, functional uterine bleeding during menopause may also occur, which is manifested by a particularly large amount of menstrual bleeding, and can be treated clinically with progestin. Therefore, if you have a particularly heavy menstrual flow, you must find out the cause and give medication according to the cause. In conclusion, if the total amount of menstrual flow exceeds 80 ml, it is an abnormal phenomenon and clinical intervention must be given.
