Blood sugar,free fatty acids and triglycerides in infants of diabetic mothers

Blood sugar (BS), free fatty acids (FFA) and triglycerides (TG) were estimated in eighteen neonates of diabetic mothers (IDM) and 36 appropriate for gestational age (AGA) term newborns of non-diabetic mothers, delivered normally and having normal blood sugar levels (30 mg/dl and above) were taken as controls. Even though blood sugar levels in the cord blood were higher in IDM group, mean levels were much lower than controls in first few hours of birth and nearly 45 per cent them developed hypoglycemia. A rise in FFA from cord levels in first few hours of birth was seen in all the cases, but levels were lower in IDM as compared to controls. TG levels showed a steady and mild rise from birth onwards. Changes in BS and FFA in IDM can be explained on the basis of hyperinsulinemic state in them in utero and in immediate postnatal period.
