IUGR
Also written as: IUGR — Intrauterine Growth Restriction
Acronym for intrauterine growth restriction, a condition where fetal growth falls below expected parameters for gestational age.
Full Definition
Intrauterine growth restriction (IUGR) refers to a condition in which a fetus fails to achieve its genetically determined growth potential in utero. Diagnosis is typically made when estimated fetal weight falls below the 10th percentile for gestational age, though some definitions use the 5th percentile. IUGR can result from maternal factors (hypertension, diabetes, malnutrition), placental insufficiency, or fetal abnormalities. It is associated with increased perinatal morbidity and mortality, requiring careful monitoring and often early delivery.
Usage
Usage note: Use all capitals. When spelled out, prefer 'intrauterine growth restriction' over 'retardation' in modern usage.
