The recovery time of the endometrium after diagnostic scraping varies depending on the degree of injury. If the basal layer of the endometrium is damaged or there is infection or adhesion, the endometrium may never return to normal after the procedure, resulting in clinical manifestations such as low menstrual flow, amenorrhea, and secondary infertility. If the basal layer of the endometrium is not damaged and there are no other complications, the endometrium may completely return to normal about 3 months after surgery. In addition, if persistent menstrual abnormalities occur after diagnostic curettage, hysteroscopy should be performed at the hospital gynecology department in time to observe whether endometrial lesions occur. In daily life, patients are advised to eat more foods with high protein and vitamin content, such as eggs, milk, vegetables, fruits, seafood and gum, etc. Avoid cold and spicy, stimulating and overly oily foods. At the same time, patients should take appropriate bed rest, avoid overexertion, and avoid sexual intercourse and bathing for 1 month to promote early recovery of the endometrium.
