Stress hyperglycemia

Stress hyperglycemia is a heterogeneous entity with unique pathophysiological features. Present practice is to treat hyperglycemia irrespective of its cause. The optimum target glucose range in stress conditions is still undefined, and different targets should be compared on the basis of their risk-to-benefit ratios and individualized decision should be taken. Still large prospective studies with follow-up data comparing diabetes and stress hyperglycemia are needed.
