Whether endometrial thickening can be removed by outpatient scraping is related to the cause of endometrial thickening, which may or may not be removed. If the endometrial thickening is not serious, and the endometrial thickening is considered to be simple, the endometrial thickening can usually be scraped off in the outpatient clinic, but after scraping off the endometrial thickening, you need to observe your body more closely to determine whether there are any infections and other symptoms. If the endometrial thickening is caused by endometrial polyps or endometrial lesions, it cannot be removed by scraping, and hospitalization is needed for surgical treatment. Thickness of the lining of the uterus may be simple, or it may be due to diseases such as endometrial cancer, so it is necessary to understand the cause before treating the symptoms.
