Infants with asymmetric IUGR may have the potential for normal growth and development because their vital organs, such as the brain and heart, receive adequate blood flow even though their body size and weight are small. Asymmetric IUGR usually occurs in the latter half of pregnancy and is caused by placental insufficiency or maternal malnutrition. The weight of infants with asymmetric IUGR is usually lower than the weight of those with SGA, although their length and head circumference may be proportionate or slightly smaller. Symmetric IUGR, which occurs in the first half of pregnancy, is usually caused by genetic or chromosomal abnormalities, infections, or exposure to toxins, and affects both the body size and organ development of the fetus.
