intrauterine growth acceleration
Abnormally rapid fetal growth velocity resulting in birth weight above the 90th percentile for gestational age.
Full Definition
Intrauterine growth acceleration refers to excessive fetal growth velocity that results in estimated fetal weight or actual birth weight above the 90th percentile for gestational age. This condition is most commonly associated with maternal diabetes mellitus (gestational or pre-gestational), maternal obesity, or genetic factors. Accelerated growth increases risks of shoulder dystocia, birth trauma, cesarean delivery, and neonatal complications including hypoglycemia and respiratory distress. Close monitoring and delivery planning are essential.
Usage
Usage note: Distinguish from simply being 'large for gestational age' which may be constitutional.
