The observation that these asymptomatic hypoglycemic episodes were significantly correlated with insulin levels at 2-h during an OGTT, combined with the present results showing a significant correlation between insulin clearance and insulin levels at 2-h during an OGTT, raises the possibility that hypoglycemia occurring during the late post-prandial period in IGT individuals may be a consequence of a prolonged elevation of insulin due to reduced insulin clearance. Here, INS is linked to Hypoglycemia.
