Excessive menstruation can lead to anemia. When menstruation is excessive, you can first take medication to stop bleeding to prevent excessive blood loss causing hemorrhagic shock. But simply stopping the bleeding is not possible. Even if the bleeding stops, it is still necessary to clarify what the cause of the disease is. Excessive menstruation is considered to be caused by gynecological diseases, such as uterine fibroids, endometrial polyps or endometrial hyperplasia, etc., you should go to the hospital in time for checkups and ultrasound to understand the condition of the uterus and adnexa, and identify the cause of the disease and carry out symptomatic treatment. If necessary, hysteroscopy and diagnostic curettage may be needed. Hysteroscopy and diagnostic curettage can play a diagnostic role as well as a therapeutic role. Anemia caused by excessive menstruation can be restored by oral iron supplementation medication to replenish the blood, but oral intake is slower. The exact treatment of anemia depends on the degree of anemia, and if the anemia is severe, a blood transfusion may be needed for treatment if necessary.
