Whether a woman’s endometrium needs diagnostic scraping needs to be assessed by the doctor in conjunction with the patient’s age, the degree of bleeding, the duration of bleeding, and the thickness and morphology of the endometrium under ultrasound to determine whether diagnostic scraping is needed. 1. If the thickness of the endometrium is more than 4mm after menopause, or if there is persistent dark separation of fluid in the uterine cavity, it is necessary that the thickening of the endometrium is related to the abnormally high level of estrogen in the body, which may easily lead to the inability of the endometrium to shed completely for a long period of time, resulting in the endometrial pathology. 2. If the uterus bleeds a lot, it is possible that there is a case of diagnostic scraping to stop the bleeding. 3. If the bleeding is profuse, it is also an indication for diagnostic scraping. 4. Abnormal endometrial echogenicity on ultrasound, such as more than 14mm, or the presence of echogenicity, may require diagnostic scraping. For women after diagnostic scraping surgery, they should pay attention to rest, eat more fresh vegetables and fruits, and keep the vulva dry and clean, and change underwear frequently. It is recommended that any discomfort should be treated promptly by a doctor to find out the specific cause and actively treat it, so as to avoid delaying the condition.
