Of six infants of gestational diabetic mothers (IGDM), the levels of insulinwere high in four during the first week of life; levels of free fatty acid and glucose tended to be low. Growth hormone values were within normal limits.
In six infants of overt diabetic mothers, five had significant hypoglycemia; three were symptomatic. Growth hormone levels were within normal limits.
There was a positive correlation between the mother's blood glucose and the infant's insulin level at delivery in five of the IGDM. After birth, a negative correlation was found between the infant's blood glucose and the plasma insulin. There was apositive correlation between weight and insulin levels at birth in twenty normal infants and five growth hormone levels and birth weight 1967.
