Endometrial polyps require surgical intervention in cases of menstrual changes, large polyp size, and interference with pregnancy. 1. Menstrual changes: endometrial polyps may cause menstrual changes, such as increased menstrual flow and prolonged menstrual period, which require surgical intervention. 2. Large size of polyps: If the endometrial polyps are large in size and cancerous when they exist for a long time, early surgical treatment is recommended. 3. Impact on pregnancy: endometrial polyps will have an impact on the embryo’s implantation and development. For women in their reproductive years, polyps need to be removed if there are repeated miscarriages, infertility and other conditions. If you have endometrial polyps, it is recommended that you consult a doctor in a timely manner, and after the doctor’s consultation, the size of the polyp and the woman’s condition will be taken into account in order to formulate a reasonable treatment plan.
