The difference between bleeding after laparoscopic surgery and menstruation mainly includes the amount of bleeding, bleeding time and so on. 1. Bleeding volume: the bleeding volume after laparoscopic surgery is generally smaller; the bleeding volume of menstruation is more than that of the former. 2. Bleeding time: the bleeding time of the former is relatively short, usually occurs during or after laparoscopic surgery, while the bleeding of the latter is usually regular, usually 21-35 days, and the bleeding usually lasts for about a week. In summary, the two are still relatively well differentiated. If laparoscopic bleeding is serious after laparoscopic surgery, it is necessary to consult a doctor in time, actively stop bleeding, and if the bleeding is large, it is necessary to carry out blood transfusion, or even secondary surgery and other treatments.
