If the menstrual flow is particularly heavy, more than twice the usual menstrual flow, and there are symptoms of dizziness, it may be caused by abnormal uterine function bleeding, or of course, by organic lesions such as endometrial thickening, submucosal fibroids or polyps, etc. In this case, it is best to go to the emergency department of a regular hospital as soon as possible to stop the bleeding and regulate the menstruation after stopping the bleeding. If blood is drawn for routine blood tests and anemia is found to be more serious, you will need to take blood supplementation medication and, if necessary, a blood transfusion. In addition, if there is no organic lesion, you should regulate your menstruation with some progesterone to reduce the amount of menstruation, or intrauterine placement of Mannitol, an imported ring to reduce the amount of menstruation. If the menstrual flow is only a little more than usual, but there are symptoms of dizziness, ultrasound examination can be performed to rule out organic lesions.
