Fetal macrosomia
Fetal macrosomia
Fetal macrosomia (pronounced: fee-tal ma-kro-so-mia) is a medical condition where a newborn is significantly larger than average. The term is derived from the Greek words "makros" meaning large, and "soma" meaning body.
Definition
A baby diagnosed with fetal macrosomia has a birth weight of more than 8 pounds, 13 ounces (4,000 grams), regardless of his or her gestational age. About 9% of babies worldwide weigh more than 4,000 grams.
Causes
Fetal macrosomia is more likely to occur in mothers with gestational diabetes or obesity. It can also occur if the mother has had previous births with large babies, is carrying more than one baby, or if the pregnancy goes beyond 40 weeks.
Complications
Fetal macrosomia can lead to complications for both the mother and the baby. For the mother, these can include labor problems, a higher likelihood of a Cesarean section (C-section) and postpartum hemorrhage. For the baby, complications can include low blood sugar, jaundice, and a higher risk of obesity and type 2 diabetes in later life.
Treatment
Treatment options for fetal macrosomia depend on the estimated fetal weight and the mother's health and obstetric history. Options can include a planned C-section or induced labor. After birth, the baby will be monitored for signs of hypoglycemia and other potential complications.
