The best time to scrape the uterus for women with thick endometrium is usually recommended to be about 3 days after menstrual cleansing. The normal endometrial thickness is 5-12mm. Patients with endometrial thickness over 12mm, accompanied by prolonged menstrual cycle and irregular vaginal bleeding, need to have a timely curettage in order to improve the symptoms and send the scraped endometrium for pathological examination to clarify the specific situation. After the curettage, the patient may have a small amount of vaginal bleeding, which will become less and less as she recovers. If the bleeding becomes heavier and significantly exceeds the amount of menstruation, accompanied by pain in the lower abdomen, it is important to follow up with the gynecologist in a timely manner. After curettage, bed rest is needed for 2-3 days, then gradually increase the amount of exercise. After surgery, we should strengthen local care of the vulva, keep the vulva clean and hygienic, and prohibit intercourse and sitz bath for a short period of time to avoid reproductive tract infection.
