During pregnancy, expectant mothers always pay extra attention to the weight of the fetus, as it not only affects the healthy growth of the fetus, but also to some extent determines the mother's mode of delivery. With the help of ultrasound data, the weight of the fetus can be calculated. However, the measurement is not entirely accurate, and there may also be some discrepancies. So, how to calculate a child's weight based on an ultrasound scan?
During the first three months of pregnancy, women mainly calculate the fetal length by measuring the distance from the fetal head to the buttocks. As the fetus gradually develops, starting from the 15th week of pregnancy, the fetal head circumference or the diameter between the two parietal bones, abdominal circumference, and femur length are measured separately to determine the size of the fetus, and then to estimate the fetal weight.
Although the weight of the fetus is one of the important indicators for judging the development and health of the fetus. However, due to individual differences in the situation of each expectant mother, there may be some errors in the fetal weight calculated through ultrasound single data, which is a reference data for knowledge.
In the fetal and neonatal period, if the baby is too light, it may suffer from malnutrition and low resistance, which will weaken the baby's resistance to infectious diseases and parasitic diseases and easily be defeated by germs. If the fetal weight is too large, it can lead to a greater possibility of difficulty and difficulty in natural childbirth. So, weight monitoring of the fetus during late pregnancy can help with the development of the fetus and provide reference for the mother's mode of delivery.
