Fetal crown-rump length standard comparison table

During pregnancy, pregnant women should closely observe the development of the fetus at all times. However, the fetus cannot be directly observed in the mother's body, so there are some standards to judge whether the fetus is well developed. For example, the fetal crown-rump length standard is a better standard. Such data can be used to observe the development of the fetus, especially after the second trimester. This is an important standard for estimating the fetal weight and height.

What to do if the fetus's biparietal diameter is too large

The larger biparietal diameter of the fetus is a sign of larger fetal development, which is directly related to the good nutrition and low activity level of the expectant mother. It shows that the adequate nutrition of the expectant mother has caused the larger development of the fetus. This is a common symptom nowadays, so there is no need to worry. As long as there is no abnormality in the fetus's head, you can rest assured.

However, if the biparietal diameter of the fetus is too large, the first thing to consider is hydrocephalus. It is recommended to pay attention to checking the fetal brain during B-ultrasound to rule out the possibility of abnormal development of the baby.
