Effect of epinephrine on glucose metabolism in humans: contribution of the liver. Abstract. Epinephrine causes a prompt increase in blood glucose concentration in the postabsorptive state. This effect is mediated by a transient increase in hepatic glucose production and an inhibition of glucose disposal by insulin-dependent tissues. Epinephrine augments hepatic glucose production by stimulating glycogenolysis and gluconeogenesis.
Insulin levels fall, glucagon and epinephrine levels rise, and more glucose is available in the blood stream. During stressful situations, epinephrine (adrenaline), glucagon, growth hormone and cortisol play a role in blood sugar levels. Stressful situations include infections, serious illness or significant emotion stress.
