What Causes Fetal Macrosomia?

Fetal macrosomia is a medical term used to describe a fetus when they overly large before birth. Although there are no set criteria for diagnosis, doctors will declare a baby with fetal macrosomia if they exceed 8 pounds and 13 ounces at birth.

This condition is quite common, accounting for almost 10% of pregnancies, and even more common in mothers with gestational diabetes. Fetal macrosomia can be dangerous as it puts the mother at high risk during her pregnancy. Now you may be wondering, what causes fetal macrosomia? Well, the Dolt, Thompson, Shepherd & Conway, PSC is here to answer that for you.


One of the most common causes of fetal macrosomia is genetics. If a mother has large physical traits or is obese, often that will pass on through genetic inheritance. On top of that, the gender of a mother’s baby plays a huge role in its size. If a mother gives born to a male baby, they are at a higher risk of fetal macrosomia as male babies tend to be bigger. Lastly, mothers with diabetes or those with gestational diabetes are ten times more likely to give birth to macrosomic babies.

Doctors usually monitor the baby’s weight throughout birth which can help prevent high-risk labor. If there are risks posed by fetal macrosomia, a doctor will most likely order a C-section. However, suppose a doctor is aware of the risks fetal macrosomia poses and refuses to order a c-section. In that case, you may be able to file a birth injury claim if you or your baby sustained severe injuries.
