What does EFW mean by foetus?

EFW is an estimate of fetal weight. Fetal weight is measured to see if it matches the gestational age. Fetal weight is calculated based on the biparietal diameter, femoral length, abdominal circumference, etc. of the fetus in the B-ultrasound examination. The calculated value is not very accurate, but it can be used as a reference for obstetricians to make decisions. Pregnant women should pay attention to the growth of fetal weight, do regular prenatal check-ups, pay attention to their own diet control and nutrition intake during pregnancy, prevent pregnancy hypertension and diabetes caused by excessive nutrition, and prevent the adverse effects of pregnant macrosomia on childbirth. Pregnant women should take appropriate physical exercise if their body allows.
