Anovulatory dysfunction, in which the ovaries do not ovulate during ovulation and the endometrium is only affected by estrogen but not by progesterone, causes the endometrium to show different degrees of value-added changes, resulting in excessive thickening of the endometrium, which can lead to breakthrough bleeding, heavy bleeding and prolonged periods. Progesterone drugs can be given to counteract the high estrogen levels in the body so that the endometrium does not thicken excessively and peeling can occur periodically. Repeated anovulatory dysfunction can easily lead to anemia in women. Adolescent women should be treated by stopping the bleeding and adjusting the menstrual cycle, while menopausal women should be treated by controlling the bleeding and preventing endometrial hyperplasia.
