Biparietal Diameter (BPD) is a crucial measurement included in fetal ultrasound. Through this measurement, doctors can assess the baby’s development and estimate the baby’s weight and size at birth.

Rapid fetal weight gain isn’t good for the baby or the mother. It increases the chances of needing a C-section and raises risks like gestational diabetes and complications during and after birth. So, what should a mother pay attention to when the fetus is found to be overweight?

If the biparietal diameter, the fetal head measurement, is larger than normal, a vaginal delivery could pose significant risks for both the mother and baby during labor. However, for more precise assessments, doctors will combine the biparietal diameter measurement with other fetal parameters, such as abdominal circumference and femur length.
