The pathophysiology of "happy" hypoglycemia

摘要: Background Hypoglycemia usually includes various neurological symptoms, which are the consequence of neuroglycopenia. When it is severe, associated with altered mental status, even coma. Case presentation We report case a patient severe hypoglycemia, completely asymptomatic, due to increase lactate production in response tissue hypoperfusion following hemorrhagic shock. This illustrates that can substitute glucose as an energy substrate for brain. It also reminder this metabolite, despite its bad reputation maintained by role marker severity critical care patients, has fundamental our metabolism. Conclusions Following example "happy hypoxemia" recently reported literature describing asymptomatic hypoxemia COVID-19 we describe hypoglycemia."
