An abortion is more painful than a medical abortion, but if a painless abortion is used, a medical abortion may be more painful than a painless abortion. Medical abortion involves oral administration of mifepristone and misoprostol to promote uterine contractions and expel the pregnancy sac, but the medications work for a long time and the pain may last from the time the medication is taken until the sac is expelled, which is a longer period of pain. When performing abortion, no matter dilating the cervix or suctioning out the embryonic tissues from the uterine cavity, there will be painful sensation, but the abortion procedure is shorter and only takes a few minutes to complete, so the pain time is very short. Most women now use painless abortion, which reduces the pain of the procedure through general anesthesia, and there is no pain sensation throughout the entire procedure, with only slight swelling and pain when the uterus contracts after the procedure. Therefore painless abortion should be less painful than medical abortion. When choosing to terminate a pregnancy, patients should listen to the advice of a professional doctor and choose the appropriate abortion method to reduce the pain of abortion.
