Factors controlling normal fetal growth and outline intrauterine growth retardation, IUGR, intrauterine growth restriction the causes of intrauterine growth retardation (IUGR) intrauterine growth retardation, IUGR, fetal growth restriction
A. Infants that do not grow appropriately in utero and are, therefore, small for gestational age at birth, are growth-retarded or restricted
Generally, the IUGR infants are in the first to tenth percentlie intrauterine growth retardation, IUGR, intrauterine growth restriction intrauterine growth retardation, IUGR, growth restriction of weight forage
The diagnosis, therefore, requires that two things must be known intrauterine growth retardation, IUGR, fetal growth restriction intrauterine growth retardation, IUGR, intrauterine growth restriction intrauterine growth retardation, IUGR, growth restriction
IUGR is important, for it has a significant perinatal morbidity intrauterine growth retardation, IUGR, growth restriction (50%) and mortality (up six to eight times)
The normal fetus needs three substrate items to grow
It receives glucose (O) across the placenta from the mother by facilitated diffusion
Oxygen (02) by simple diffusion
It also receives amino acids (AA) by active transport
The fetal concentration of AA is higher, the concentration of G intrauterine growth retardation, IUGR, fetal growth restriction
