Bleeding half a month after uterine fibroid surgery may be caused by poor uterine contraction, postoperative infection, being in the menstrual period and so on. 1. Poor uterine contraction: if the patient’s physical condition is poor and the uterus recovers too slowly, it may lead to poor uterine contraction and cause prolonged bleeding time after surgery. 2. Post-operative infection: if the patient is infected by pathogens after fibroid surgery, it may cause the endometrium to be damaged again, thus affecting the repair of the wound. 3. Being in the menstrual period: if the bleeding after uterine fibroid surgery has just improved and is close to the menstrual cycle, it may manifest as continuous bleeding up to half a month, at this time, there is no need to worry too much. There may be other reasons for bleeding after uterine fibroid surgery. It is recommended to go to the hospital in time, improve the examination to clarify the cause of the disease, and then give targeted treatment or therapy under the guidance of the doctor.
