Bleeding after 10 days of hysterectomy may be related to wound infection, detachment of vaginal stump line, rupture of small blood vessels and so on. 1. Wound infection: Wound infection is the direct cause of bleeding, due to the low resistance of the patient after the operation, if the care is not proper, so that the bacteria and viruses invade, resulting in tissue infection and suppuration, bleeding will occur. 2. Vaginal stump line detachment: Generally when the stump line detaches, it may cause a small amount of bleeding, which mainly belongs to the poor stump suture and blood vessel exposure, and a small amount of bleeding can be left untreated. If a large amount of bleeding occurs, urgent re-suturing should be done to stop bleeding. 3. Rupture of small blood vessels: If postoperative strenuous activities lead to the rupture of small blood vessels at the suture site of the wound, it can also lead to bleeding. If there is a large amount of bleeding, prompt medical attention should be sought. If bleeding persists after the operation, you should go to the hospital in time, complete the relevant examinations, clarify the cause of the disease under the guidance of professional doctors, and actively target treatment.
