FGR
Also written as: FGR — fetal growth restriction
Fetal growth restriction; condition where fetus fails to achieve genetic growth potential, replacing older term IUGR in current practice.
Full Definition
Fetal growth restriction (FGR) represents a pathological condition where the fetus fails to achieve its genetically predetermined growth potential, typically defined as estimated fetal weight below the 10th percentile for gestational age with abnormal Doppler studies or other markers of placental insufficiency. This term has largely replaced 'intrauterine growth restriction' (IUGR) in contemporary obstetric practice. FGR results from maternal, fetal, or placental factors and is associated with increased perinatal morbidity and mortality. Diagnosis relies on serial biometry, amniotic fluid assessment, and umbilical artery Doppler studies. Management includes enhanced fetal surveillance and appropriately timed delivery.
Usage
Usage note: Preferred term over IUGR in modern practice; editors should note this terminology shift.
