When the color ultrasound report shows that the fetal biparietal diameter is too large, we should first consider whether it is caused by pathological factors. If the fetus has hydrocephalus, it will lead to a large biparietal diameter. Therefore, it is necessary to judge whether there is abnormal brain development such as hydrocephalus by color Doppler ultrasound. At the same time, if pregnant women suffer from gestational diabetes and their blood sugar is too high, it will lead to fetal growth, and the biparietal diameter will naturally be too large. These factors need symptomatic treatment to make fetal health more ideal.
If pathological factors are excluded, the larger biparietal diameter may be caused by the rich diet of expectant mothers during pregnancy, so don't worry. In addition, genetic factors will also affect the size of fetal biparietal diameter. In addition, if both parents are big heads, it is also common that the fetal biparietal diameter is too large.
