A friend sent me a list of allll the things that can go wrong with untreated GD.
Hypertension (High blood Pressure)
Diabetic Ketoacidosis (DKA)
Macrosomia (large baby)
Neonatal hypoglycemia is defined as low blood sugars in the baby after birth. If the baby's pancreas is making large amounts of insulin in response to the mother's high blood sugars, it will continue to do so for a time after delivery. Since the sugar supply from the mother is no longer present once the baby has delivered, blood sugar can drop too low (hypoglycemia, blood sugar < 40 mg/dl). The baby can become fussy, jittery or may even have a seizure or breathing problems.
Other Neonatal Metabolic Problems
In addition to hypoglycemia, the excess insulin can also infrequently be responsible for other metabolic complications such as jaundice (yellowing of the skin) and imbalances of calcium or magnesium. The chances of a baby being born with diabetes are extremely rare particularly in cases where the mother has gestational diabetes.
When blood sugars are persistently high, blood vessel damage in the placenta and poor oxygen and nutrient supply to the baby can occur. This decrease in oxygen may cause health damage to the baby including death or stillbirth.
The most common birth defects are those of the brain, spinal cord and heart.
