Diagnostic curettage for thick endometrium generally refers to diagnostic curettage for thick endometrium, while miscarriage generally refers to abortion, and the two are not equivalent. The purpose of diagnostic curettage for endometriosis is to stop bleeding and diagnose the presence of pathology. Usually, diagnostic curettage intercepts part of the uterine lining, which does not have a serious impact on women’s health, except for a small amount of vaginal bleeding. However, some miscarriages may need to undergo purging, curettage or forceps to remove residual tissues in the uterine cavity, and the scope of surgery is relatively extensive. Therefore, diagnostic curettage for endometrial thickness is not equivalent to abortion. Usually, abortion will have a certain impact on a woman’s physical and mental health, and she needs to rest for about 2-3 weeks after the abortion to promote the recovery of her body. Women who have had a miscarriage need to be examined by a doctor before they are ready to get pregnant again, in order to clarify the cause of the miscarriage and prevent it from happening again. It is recommended that people with thick endometrium should consult a regular hospital for diagnostic scraping, and after the examination, strengthen personal hygiene care to prevent endometritis, vaginitis and other diseases.
