if a woman is diagnosed with gestational diabetes, she should be instructed about proper diet and blood glucose testing. if her blood sugar is not brought into the normal range for pregnancy despite diet and medically cleared physical activity, the most common choice of medication is insulin injection. if GDM is not controlled, the baby is almost always born weighting more than nine ponds (he was overfed glucose in utero) and may develop hypoglycemia upon delivery. the child may also be prone to type 2 diabetes later in his life.
