What is fetal macrosomia?
Fetal macrosomia, arbitrarily defined as a birth weight of more than 4,000 g (8 lb, 13 oz) complicates more than 10 percent of all pregnancies in the United States. It is associated with increased risks of cesarean section and trauma to the birth canal and the fetus.
Can macrosomia be treated?
Objective: Treatment of fetal macrosomia presents challenges to practitioners because a potential outcome of shoulder dystocia with permanent brachial plexus injury is costly both to families and to society. Practitioner options include labor induction, elective cesarean delivery, or expectant treatment.
Is macrosomia considered high risk?
Is Fetal Macrosomia Dangerous? Most of the time, babies born with fetal macrosomia do not experience any problems. However, a mother who is pregnant with a baby with macrosomia is considered to have a high-risk pregnancy. Both the baby and the mother could have serious, even life-threatening medical complications.
Why is macrosomia bad?
For the infant, macrosomia increases the risk of shoulder dystocia, clavicle fractures and brachial plexus injury and increases the rate of admissions to the neonatal intensive care unit. For the mother, the risks associated with macrosomia are cesarean delivery, postpartum hemorrhage and vaginal lacerations.
Is macrosomia a birth defect?
When the birth is delayed and obstructed by the baby’s large size, they are at risk of suffocating, known as birth asphyxia. Births involving fetal macrosomia are also at risk of birth defects and injuries, like a fractured clavicle or damage to the nerves of the brachial plexus.
What are the complication of macrosomia?
Significant maternal and neonatal complications can result from the birth of a macrosomic infant, and include prolonged labor, operative delivery, postpartum hemorrhage, perineal trauma, shoulder dystocia, birth trauma, chorioamnionitis, meconium aspiration, perinatal asphyxia, low Apgar scores, neonatal hypoglycemia.
Are big babies healthier?

The scientists found that birth size influenced intelligence until about the age of 26.
Is it bad to have a 10lb baby?
A baby that weighs more than 10 pounds poses the risk of delivery complications such as excessive bleeding for the mother, increasing the likelihood of long-term nerve injuries or needing a c-section. Even then, the risk of bleeding and delivery complications loom.

Can a large fundal height be a sign of macrosomia?
Large fundal height. During prenatal visits, your health care provider might measure your fundal height — the distance from the top of your uterus to your pubic bone. A fundal height that measures larger than expected could be a sign of fetal macrosomia.
