Whether endometrial thickening must be treated with curettage depends on the degree of endometrial thickening and the presence or absence of accompanying symptoms. If the endometrial thickening is greater than 12 mm, but is not accompanied by incomplete menstruation or increased menstrual flow, and if the woman is an adolescent, she can usually be treated without scraping and with estrogen or progestin medication to stop the bleeding. However, in perimenopausal women with incomplete or increased menstrual bleeding, scraping is usually required to stop the bleeding and then send the patient for examination to exclude endometrial lesions. If there is irregular bleeding, particularly prolonged or incomplete periods, scraping can be performed under ultrasound monitoring or hysteroscopy. After the endometrium is removed, pathological tests can be performed and the corresponding treatment can be administered according to the results of the pathological tests. After endometrial curettage, it is important to observe the amount of vaginal bleeding and vaginal discharge for abnormalities and seek medical attention promptly. At the same time, it is necessary to strengthen the local care of the vulva, keep the local cleanliness, avoid sitz bath and sexual life to avoid reproductive tract infection.
