macrosomia
Pronunciation: mak-roh-SOH-mee-uh
Fetal condition characterized by excessive birth weight, typically defined as greater than 4000-4500 grams or above the 90th percentile for gestational age.
Full Definition
Macrosomia describes newborns who are significantly larger than average for their gestational age, most commonly defined as birth weight exceeding 4000-4500 grams. This condition is often associated with maternal diabetes, previous history of macrosomic infants, or maternal obesity. Macrosomic babies face increased risks of birth trauma, shoulder dystocia, and neonatal hypoglycemia. The condition also increases maternal risks during delivery, potentially necessitating cesarean section.
