Laser treatment of cervical erosion is also a common gynecological treatment that uses high temperatures to carbonize and crust the cervical tissue. After the crusts fall off, the cervical tissue regenerates and the wound is repaired, making the surface of the cervical tissue smooth again, thus achieving the goal of treatment. However, after laser treatment, the elasticity of the cervical tissues will become less elastic and slightly hard, so that during childbirth, the expansion of the cervix will be affected, and cervical lacerations may even occur, mainly during vaginal delivery. Therefore, laser treatment is not suitable for women who are preparing for childbirth. After laser treatment, you should pay attention to keep your vulva clean, forbid sex and tub or sitz bath for two months, forbid vaginal medication and vaginal douche, and follow up with the hospital in time if there is much bleeding.
