Abstract

Macrosomia is defined as a birth weight over 4000–4500 g and is associated with an increased risk for shoulder dystocia. Women with overt or gestational diabetes are more likely to have macrosomic fetuses because maternal hyperglycemia results in infant hyperinsulinemia causing accelerated growth [1].
