Uterine fibroids are a common disease in gynecology, the typical symptoms of which are irregular menstruation, often manifested as increased menstrual flow, prolonged menstrual period, incomplete menstruation, etc. In theory, the situation of heavy menstrual flow after uterine fibroids surgery will improve, but some people have heavy menstrual flow after surgery, which may be related to the following factors: 1, the uterus has not fully recovered in the early postoperative period, and the contraction force of the uterine muscle layer has not fully recovered, so the increased menstrual flow after surgery. 2, the ovarian function, such as perimenopausal women, ovarian hypofunction, follicular dysplasia, and ovulation disorders, postoperative trauma induced menstrual irregularities, causing heavy menstrual flow. In this case, regular progesterone supplementation is needed to adjust the menstrual cycle and control the menstrual flow.
