A second pregnancy one and a half years after a cesarean section can usually be continued under close monitoring if there are no special circumstances.
Under normal circumstances, the incision heals three months after the cesarean section, and the thickness and elasticity of the uterine wall return to normal about two years after the operation, so it is clinically recommended that the pregnancy should continue two years after the cesarean section.
If there are no serious complications at the time of cesarean section, pregnancy can be resumed one and a half years after the operation, when the uterus has basically returned to its normal state, but it is necessary to do a comprehensive examination to make sure that there is no obvious hyperplasia of the surgical scar and that the placenta is not attached to the scar.
Moreover, regular pregnancy checkups are needed during the second pregnancy to observe the growth and development of the fetus; diet control is also needed to prevent uterine rupture caused by an oversized fetus.
If you are pregnant again after one and a half years of cesarean section, it is recommended to go to a regular hospital for a comprehensive examination and have the pregnancy conditions judged by a professional doctor, so as to avoid adverse consequences.
