Smoking is not allowed until at least one month after the abortion. During abortion, due to the damage caused to the uterine lining, bleeding will occur after the operation, which lasts for about one week, and after the bleeding stops, the uterine lining will start to repair, and it will take at least one month to repair the uterine lining basically. It takes at least a month for the basic repair of the uterine lining. Smoking releases harmful substances, which will affect the repair of the uterine lining to a certain extent, so it is recommended that you should not smoke until after the basic repair of the uterine lining. In addition to not smoking, you should not have sex or take a bath for a month after the abortion, especially before the bleeding stops. At this time, the cervix is in an open state, which can easily cause endometrial infection, endometritis, pelvic inflammatory disease and so on. It should be said that it is not that you should not smoke in a month, but that women should not smoke in the first place. Harmful substances in cigarettes are very damaging to the ovaries, which can easily lead to low ovarian function, affecting the reproductive ability of women.
