Usually, the endometrium returns to normal after a diagnostic curettage in about 1 month. After having a diagnostic curettage the patient’s endometrium will become thinner, which is equivalent to having a period. After the operation, through the influence of ovarian secretion of estrogen and progesterone, the endometrium grows thicker, and usually after one month of growth, the endometrium will be stripped again and the woman will have her period, suggesting that the endometrium returns to normal. After diagnostic scraping, if infection occurs or the endometrial lining is more damaged during the scraping process and partial adhesions of the uterine cavity occur after the procedure, it may lead to a longer recovery time of the endometrium and in serious cases, it may lead to amenorrhea in patients. Therefore, patients must pay attention to aseptic operation when performing diagnostic scraping. After the operation, patients should follow the doctor’s instructions and give medication to increase nutrition, anti-infection and stop bleeding to facilitate the recovery.
