INS and gestational diabetes: Similar differences in fasting glucose and insulin concentrations to those we describe between diet and insulin treated groups were identified in women with GDM defined by a poor insulin secretion profile (fasting glucose 76mg/dl; 72–79, fasting insulin 6.0μl/ml; 4.6–6.7) or those with an insulin resistant profile (90mg/dl; 81–94, 13.6μl/ml 9.9–20.5) respectively [2].
