An IUD is not necessary after removal of a uterine polyp, but is prescribed by the doctor for the woman’s individual condition. IUD refers to the placement of an intrauterine device (IUD), which refers to the levonorgestrel intrauterine device (IUD) system. As large endometrial polyps can cause heavy menstrual periods and prolonged menstrual periods, combined with ultrasound examination and other clear diagnosis, it is recommended to carry out hysteroscopic polypectomy. After the operation, those who have fertility requirements can prepare for pregnancy under the guidance of the doctor, and do not need an IUD. However, those who do not have fertility requirements can be given an IUD after the operation to minimize the possibility of recurrence. After endometrial polypectomy, we should pay attention to appropriate rest, keep the vulva clean and dry, prohibit bath and sexual intercourse for 1 month, give antibiotics such as metronidazole to prevent infections as prescribed by the doctor, avoid early heavy labor and strenuous exercise, and follow the doctor’s instructions for follow-up examination to understand the uterine recovery.
