Women with heavy and prolonged menstruation can easily lead to anemia and decreased health. The causes are as follows: a. Women who are tired or emotionally agitated during menstruation, poor rest, or take blood-boosting drugs, resulting in heavy menstruation and prolonged periods. Second, suffering from uterine fibroids, endometrial polyps and other diseases that affect the contraction of the uterus can also lead to this situation. Third, endocrine disorders such as dysfunctional uterine bleeding or the presence of atrophy of the corpus luteum can also lead to heavy menstruation and prolonged periods. Therefore, when the menstrual flow is heavy and the period is prolonged, you can pay proper attention to rest and take oral hemostatic drugs to relieve the bleeding, or go to the hospital for gynecological ultrasound and sex hormone examination in time to take appropriate drugs or surgery according to the cause.
