Introduction
Macrosomia (large gestational age, LGA) is a term used to describe a newborn with an excessive birth weight due to a range of known and unknown causes. The definition is either a birth weight of 4000 to 4500 g (8 lb 13 oz to 9 lb 15 oz) or greater than 90% for gestational age after correcting for neonatal sex and ethnicity.
- Duration of gestation - growth past the due date.
- Maternal diabetes - presence of gestational diabetes; and class A, B, and C diabetes mellitus.
- Genetic Syndromes and Tumours - a range of overgrowth syndromes associated with developmental delay, tumors, and other anomalies with genetic causes and syndromes (Pallister-Killian, Beckwith-Wiedemann, Sotos, Perlman, and Simpson-Golabi-Behmel) rarely diagnosed prenatally.
Currently there is clinical research looking into the best mathematical formula, based upon ultrasound measurements, to estimate the possibility of macrosomia occurring.
