Does diabetes cause macrosomia?

Does diabetes cause macrosomia?

About 15-45% of babies born to diabetic mothers can have macrosomia, which is a 3-fold higher rate when compared to normoglycemic controls.

Why do diabetics have big babies?

Even when the mother has gestational diabetes, the fetus is able to produce all the insulin it needs. The combination of high blood glucose levels from the mother and high insulin levels in the fetus results in large deposits of fat which causes the fetus to grow excessively large.

What causes fetal macrosomia?

Fetal macrosomia is more likely to be a result of maternal diabetes, obesity or weight gain during pregnancy than other causes. If these risk factors aren’t present and fetal macrosomia is suspected, it’s possible that your baby might have a rare medical condition that affects fetal growth.

Does diabetes cause fetal growth?

Diabetes can also stop babies from growing normally – they are born either too small (fetal growth restriction (FGR)) or too large (macrosomia), both of which dramatically increase the risk of stillbirths.

Does gestational diabetes cause large head?

Because fetal head size is not increased during poorly controlled diabetic pregnancy, but shoulder and abdominal girth can be markedly augmented, the risk of injury to the fetus after delivery of the head (eg, Erb palsy) is significantly increased.

How can I prevent a large baby with gestational diabetes?


  1. Eat healthy foods. Choose foods high in fiber and low in fat and calories.
  2. Keep active. Exercising before and during pregnancy can help protect you from developing gestational diabetes.
  3. Start pregnancy at a healthy weight.
  4. Don’t gain more weight than recommended.

What happens if a baby is born with diabetes?

Because of the extra insulin made by the baby’s pancreas, newborns may have very low blood glucose levels at birth and are also at higher risk for breathing problems. Babies born with excess insulin become children who are at risk for obesity and adults who are at risk for type 2 diabetes.

When is macrosomia detected?

Macrosomia is diagnosed when excessive intrauterine growth occurs and the birth weight exceeds an established limit of either 4,000 or 4,500 g [1]. Approximately 10% of all newborns have a birth weight >4,000 g, and 1.5% weigh ≥4,500 g [2].

What happens to baby gestational diabetes?

Babies of mothers who have gestational diabetes have a higher risk of developing obesity and type 2 diabetes later in life. Stillbirth. Untreated gestational diabetes can result in a baby’s death either before or shortly after birth.

How common is macrosomia in gestational diabetes mellitus?

Background: Fetal macrosomia, defined as a birth weight ≥ 4,000 g, may affect 12% of newborns of normal women and 15-45% of newborns of women with gestational diabetes mellitus (GDM). The increased risk of macrosomia in GDM is mainly due to the increased insulin resistance of the mother.

What predicts macrosomia in newborns?

Gestational diabetes, preeclampsia due to diabetes, and history of macrosomic birth were the main predictors of macrosomia. Moreover, macrosomia increased some delivery complications for both mothers and newborns. Keywords: Africa, Cesarean, Diabetes, Gestational diabetes, Macrosomia, Newborn Introduction

What are the risks of fetal macrosomia?

However, the risks associated with fetal macrosomia increase greatly when birth weight is more than 9 pounds 15 ounces (4,500 grams). Fetal macrosomia may complicate vaginal delivery and could put the baby at risk of injury during birth. Fetal macrosomia also puts the baby at increased risk of health problems after birth.

What does macrosomia mean in pregnancy?
