Fetal growth restriction has normal after birth. The etiology of fetal growth restriction is very complex. Factors affecting fetal growth restriction include the mother’s factors, fetal factors, placental factors and umbilical cord factors. Whether fetal growth restriction is normal after birth is closely related to the degree of growth restriction and the cause of the growth restriction. If fetal growth restriction is severe, affecting brain development or caused by congenital malformations, the child usually remains abnormal after birth and is difficult to correct. If the growth restriction is due to severe maternal anemia, malnutrition, or poor placental function, the child is often able to develop normally if it is corrected during pregnancy and supplemented with nutrients after birth. If fetal growth restriction is detected during pregnancy, the mother does not need to worry too much, but should consult the doctor in time, and active treatment is possible to correct the problem.
