Dr. Tian Hongbo
Fetal biparietal diameter enlargement may be caused by excessive nutrition or abnormal fetal brain development. It can occur when a pregnant woman has excessive nutritional intake during pregnancy, or suffers from gestational diabetes. If blood glucose levels remain elevated throughout pregnancy, the fetal biparietal diameter tends to increase. In addition, if fetal brain development is abnormal, conditions such as hydrocephalus or cranial dysplasia may also occur.
