The main cause of endometrial adhesions is due to post-abortion complications, which may be physiological adhesions without any cause, usually without symptoms or menstrual changes, with the main effect being secondary infertility, which requires hysteroscopy. Before doing hysteroscopy, vaginal microecology should be checked to make sure that there is no vaginitis, otherwise retrograde infection will lead to worse hysteritis. It should be noted that it is best to go to the hospital 3-7 days after menstruation for surgery, when the endometrium is the thinnest and the adhesions are the easiest to find and the results will be better. After the surgery, you should pay attention to a light diet, take oral or injectable antibiotics to fight infection, and after discharge from the hospital, you should pay attention to the prohibition of sexual intercourse for 1 month, the prohibition of bathing for 1 month instead of showering, and after 1 month, you should perform relevant post-surgical examinations in the hospital, such as gynecological ultrasound, gynecological examination, etc.
