Bleeding from endometrial polyp surgery lasts for about 7 days. If the bleeding continues for 6 days after surgery, it may be normal, or there may be infection of the endometrium. 1. Normal phenomenon: endometrial polyp surgery will produce some damage to the uterine lining, the healing of the uterine lining needs some time, so there will be postoperative bleeding. 2. Endometrial infection: If the bleeding after 6 days of endometrial polyp surgery is relatively large and accompanied by symptoms such as abdominal pain, lumbago, abnormal secretions, etc., it may be infected by bacteria and other pathogens, and the endometrium is not healing well, which leads to bleeding. If the bleeding persists after endometrial polyp surgery and cannot be stopped or is accompanied by other abnormalities, it is recommended to go to the hospital in time and take reasonable methods of treatment under the guidance of the doctor to promote the alleviation of the condition.
