Bleeding 4 days after hysteroscopic surgery is usually not menstruation, it may be bleeding from the trauma of hysteroscopic surgery.
Hysteroscopic surgery is a minimally invasive procedure that is generally used in the treatment of endometriosis, uterine fibroids, uterine congenital developmental malformations and other disorders. The procedure may damage the endometrium, leading to complications such as uterine perforation, bleeding, infection, and overhydration syndrome, and there may be signs of bleeding after the procedure, but the amount of bleeding is usually not large, and the duration of the bleeding is usually not more than 2 weeks.
When patients bleed 4 days after hysteroscopic surgery, they should closely observe the amount of bleeding from the surgery, and if a large amount of fresh blood flows out, they should go to the hospital in time and under the guidance of the physician for relevant treatment.
