A 37 week old baby is already full-term, and the size of the biparietal diameter determines whether the baby's development is good and whether they can have a smooth vaginal delivery. If the biparietal diameter is too large, it can cause difficulties during delivery, leading to difficult labor. So controlling the biparietal diameter within a reasonable range is a prerequisite for a smoother delivery. So, is the 37 week biparietal diameter 9.1 too large?
At 37 weeks, the biparietal diameter is normal. At this time, the fetal weight is generally around 3 kilograms, and there is no extra space in the uterus for the baby's hands and feet to move better. Therefore, the fetus will strive to find a more comfortable position and wait for the moment of delivery.
In addition, if the fetal biparietal diameter is too large, mothers do not need to worry too much. This is mainly due to the low activity level of mothers. As long as the fetal head development is not abnormal, in the late stage of pregnancy, participate in outdoor sports more to improve physical fitness and wait quietly for the arrival of delivery. Sometimes, a fetal head that is too large is a sign of hydrocephalus. It is recommended to go to the hospital for an ultrasound to understand the fetal brain development and promptly rule out any abnormalities during the development process.
Furthermore, if the development of biparietal diameter is slightly smaller, it may be due to inadequate nutrition. It is recommended to have a regular daily diet, strengthen nutrient intake, and undergo regular check ups.
