FETAL MACROSOMIA- describes a newborn who's significantly larger than average. A baby who is diagnosed as having macrosomia weighs more 4,000 grams (8lb13oz) regardless of their gestational age. Approximately 8-9% of babies worldwide exceed this weight at birth.
Risks associated with fetal macrosomia increase greatly when birth weight exceeds 4,500 grams (9lb15oz).
Fetal macrosomia may complicate vaginal delivery and put the baby at risk of injury during birth (shoulder dystocia or trapped fetal shoulder is a commonly feared complication). Fetal macrosomia also puts the baby at increased risk of health problems after birth. Some signs of possible underlying macrosomia at prenatal visits include a large fundal height measurement {pic2} or excessive amniotic fluid (polyhydramnios) on ultrasound. Factors increasing risk for fetal macrosomia include; maternal diabetes, obesity and history of having macrosomic births.
