If there is heavy bleeding during menstruation, clinically it is likely to be functional uterine bleeding, or clinically heavy bleeding due to submucosal fibroids. Therefore, the most important thing is to have a routine blood test and then an ultrasound examination. If there is a fibroid causing heavy bleeding, surgery will be required if necessary. If a large amount of bleeding occurs when organic lesions are ruled out, it is likely to be functional uterine bleeding. In the case of functional uterine bleeding in adolescence, it is recommended to treat the bleeding with oral supplementation of Glaxo, which in most cases will significantly reduce the vaginal bleeding in about 24-48 hours. If functional uterine bleeding occurs during menopause, clinical treatment with progesterone will also reduce vaginal bleeding within 24-48 hours after administration.
