The thickness of the scar in pregnant women is around 3-5 millimeters and varies from person to person.
If a cesarean section has been performed before, the scar thickness of the lower uterine segment needs to be monitored in a second pregnancy. If the scar thickness is around 3-5 mm, it is usually normal and basically will not have a major impact on the later pregnancy.
If the scar thickness in late pregnancy is thin, the thickness of the whole layer is less than 3mm, or the continuity of the myometrium of the lower segment of the uterus is interrupted, then it needs to be highly serious, closely monitored, and vigilant for uterine rupture in late pregnancy, and terminate the pregnancy by cesarean section if necessary.
During pregnancy, regular medical checkups are needed to pay more attention to the development of the fetus and maternal factors, and if there are any abnormal reactions, timely medical attention is needed to avoid affecting the development of the later stages.
