After removing uterine fibroid, heavy menstruation is normal if it is within 2~3 months after the surgery; however, if it is more than 3 months, it may be abnormal, which may be due to infection in the uterine cavity, scar tissue hyperplasia and other reasons. 1. Normal phenomenon: uterine fibroid removal surgery may cause damage to the uterine lining, and it usually takes 2~3 months to repair the damage, before the uterine lining is not fully repaired, there may be heavy menstruation, menstrual disorders and other manifestations, but this kind of situation is mostly normal. 2. Abnormal phenomena: (1) Uterine infection: in the process of myomectomy, it may cause damage to the endometrial tissue, and some women do not pay attention to the usual local hygiene, which may cause uterine infection and lead to heavy menstruation. (2) Scar hyperplasia: the endometrium may be damaged during the excision surgery, and scar tissue may be formed during the process of wound repair, which may affect the normal contraction of the uterus when menstruation occurs, and may lead to heavy menstruation. In conclusion, whether heavy menstruation is normal or not after fibroid removal, it is recommended to go to the hospital and make a comprehensive judgment after the doctor’s interview, taking into account the time of the operation and the results of related examinations.
