The incidence of congenital anomalies increases 3 fold in infants of diabetic mothers. Abnormalities of brain development, especially neural tube defects are common in such infants. The pituitary hypoplasia may thus be linked to gestational diabetes even though there is not much proof in literature to support this view. It will be advisable to test for hyperglycaemia in early pregnancy (from first trimester itself) to avoid a similar occurrence next time.
