The thickness of the endometrium varies with the menstrual cycle. However, if the endometrium grows abnormally to more than 10 mm after menstruation, and if it is accompanied by symptoms such as incomplete bleeding and prolonged periods, endoscopic surgery is required. Care after endoscopy is also very important, but post-operative care is needed in terms of diet, daily living habits, and work schedule. The principle of endometrial scraping is actually the same as that of abortion, which is the process of scraping out the thick endometrium by using instruments to enter the uterine cavity. Inevitably, there will be bleeding and trauma during the procedure, so you need to rest in bed for 3-5 days after the procedure and not to do strenuous exercise to avoid increased bleeding. Cold, spicy and irritating foods are not allowed, such as chili peppers, barbecued foods, leeks, etc., and alcohol is prohibited. Sexual intercourse should be prohibited for one month after the operation because the pathogenic bacteria carried by men who have sex too early may enter the uterine cavity through the cervix, thus causing serious uterine infections. It is important to get enough sleep and to take the medication prescribed by the doctor on time. Wash your vulva every day, but do not bathe in a tub, only shower. There are many causes of abnormal thickening of the endometrium, so after the scraping procedure, further pathological examination of the removed endometrial tissue is needed to exclude the possibility of endometrial cancer.
