In brief: Not just big.
Fetal macrosomia can be suspected by serial ultrasound in which the fetus exceeds the 90th percentile.
This means that the baby is larger than 89% of the babies of same gestational age. Furthermore"macrocosmic" fetus are at a higher risk of shoulder dystocia (difficulty of delivering shoulders after the head is out) and hypoglycemia or dropping blood sugars shortly after delivery.
