Symptoms:

The infant is usually large for gestational age. Other symptoms may include:

• Blue or mottled skin color, rapid heart rate, rapid breathing (signs of heart failure)
• Newborn jaundice
• Poor feeding, lethargy, weak cry (signs of severe low blood sugar)
• Puffy face
• Reddish appearance
• Tremors or shaking shortly after birth

Signs and tests:

An ultrasound performed on the mother in the last few months of pregnancy shows a large for gestational age baby.

After birth, tests may show that the infant has low blood sugar and low blood calcium. An echocardiogram may show an abnormally large heart, which can lead to heart failure.
