Up to 50% of infants of diabetic mothers have low levels of serum calcium (< 7 mg/100 mL). These changes in calcium appear to be attributable to a functional hypoparathyroidism, though the exact pathophysiology is not well understood. With improved management of diabetes in pregnancy, the rate of neonatal hypocalcemia has been reduced to 5% or less.
