In the late stage of pregnancy, the fetus has already matured and the pregnant woman can start preparing for childbirth. Firstly, it is necessary to actively undergo prenatal examinations to determine whether the fetus can be delivered smoothly. Sometimes, due to irregular pelvic development in pregnant women, or if the pelvic development is too small, or if the fetal head is too large, causing fetal head pelvic mismatch, what are the reasons for fetal head pelvic mismatch?
A fetus weighing over 8 pounds is a macrosomia. The appearance of the giant is an important reason for the mismatch between the head and the bowl. Giant babies are often caused by excessive and sufficient nutrition provided by pregnant women during pregnancy. In fact, it is best to keep the size of the fetus around five or six pounds, as this type of fetus is most suitable for vaginal delivery. If the fetus is huge, its head circumference will be very large, which can easily cause fetal head pelvic mismatch.
The pelvic shape of women is not uniform. According to the different developmental shapes of the female pelvis, it can be divided into many different shapes. Among all shapes, only the female pelvis is suitable for vaginal delivery. The probability of head pelvic mismatch is relatively small, while other types such as flat pelvis and male pelvis are considered as some malformed pelvis, which are not conducive to fetal vaginal delivery and are prone to head pelvic mismatch.
In summary, fetal head pelvic mismatch may be caused by both fetal factors and pelvic dysplasia in pregnant women. Therefore, in order to have a smooth delivery, it is best to actively undergo prenatal checkups to understand if there is any head pelvic mismatch. If the head and pelvis are not compatible, the probability of vaginal delivery will be very low.
