IUGR
Also written as: IUGR — intrauterine growth restriction
Intrauterine growth restriction - condition where fetal growth is below expected parameters.
Full Definition
Intrauterine growth restriction (IUGR) describes inadequate fetal growth, typically defined as estimated fetal weight below the 10th percentile for gestational age. IUGR can be symmetric (affecting all fetal parameters equally) or asymmetric (primarily affecting abdominal circumference). Causes include placental insufficiency, maternal hypertension, infection, or genetic abnormalities. The condition requires intensive monitoring and may necessitate early delivery.
Usage
Usage note: Use capital letters. Some centers prefer FGR (fetal growth restriction) - check local style guides.
