Usually a 2.0mm thickness of the lower anterior wall of the uterus is not enough for a normal delivery, and some abnormalities may occur, so a normal delivery is not recommended. In women who have had a cesarean section, the thickness of the myometrium of the lower anterior wall of the uterus needs to be monitored after a second pregnancy. This is because the thickness of the myometrium represents the thickness of the scar, and if the scar is too thin, it increases the risk of uterine rupture. In clinical practice, the thickness of the myometrium of the lower uterine segment is 3.0mm before normal delivery. If the thickness is not up to the standard, choosing to have a normal delivery will increase the probability of localized uterine rupture or rupture of the uterus to a certain extent, and in severe cases, it may lead to hemorrhage, fetal birth abnormality, and the risk of having a normal delivery is relatively high. It is recommended that women undergo a detailed physical examination before delivery, and choose a way of delivery that suits their situation under the guidance of the doctor to avoid other problems. Attention should be paid to more rest, at the same time should relax, avoid tension, anxiety, any discomfort should promptly go to the hospital, the doctor to clarify the diagnosis, and cooperate with the doctor to deal with the symptoms.
