Lipo knife surgery can affect pregnancy. Lipo knife surgery is used to treat more severe cervical erosion and cervical intraepithelial lesions by conical excision of the cervix with the cervical canal as the longitudinal axis, the cervical histological inlet as the apex and the cervical surface as the bottom. This procedure is more thorough, but it shortens the length of the cervix considerably. In the middle and late stages of pregnancy, as the pregnancy gradually increases in size in the uterine cavity, the connection between the cervix and the uterine body is gradually stretched into the lower segment of the uterus. The weakness of the tissue in the lower segment of the uterus after the Lipo knife surgery treatment may lead to the prolapse of the pregnancy to trigger midterm miscarriage, and preterm and emergency delivery may also occur in late pregnancy. The treated cervix has a scar that exists and the hard scar tissue may also lead to poor softening of the cervix during full-term delivery, which may affect the progress of labor. Therefore, Liposuction is not recommended for unmarried women.
