If the thickness of the endometrium is 14mm before the patient’s menstruation, there can be no need to scrape the uterus. If the thickness of the endometrium is still 14mm after menopause and normal menstruation, scraping needs to be considered. There is a certain pattern of endometrial thickness. Generally, the endometrium is thickest before menstruation, which can reach about 10~12mm or even thicker. If the patient’s endometrial thickness is 14mm before menstruation, and the normal endometrial thickness is restored after menstruation, he/she can not need to scrape the uterus, which belongs to the normal endometrial thickness. If the endometrial thickness is still 14 mm after menopause and normal menstruation, and if postmenopausal bleeding, excessive menstruation or prolonged menstruation is caused by endometrial thickening, it is necessary to consider scraping the uterus to rule out the abnormality. Endometrial thickening is generally associated with high estrogen, and it is recommended that if abnormal endometrial thickness occurs, it is important to go to the hospital in a timely manner for symptomatic treatment and follow up with any discomfort.
