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.
Increased stressed levels can cause a decrease in epinephrine levels, causing you to crave sugar to increase energy levels. Unfortunately, the effects of sugar wear off rather quickly, causing further sugar cravings and creating a vicious cycle.f you suffer from regular sugar cravings, it is important to find a way to break free of them so that you can live a healthier lifestyle. One way to do this is to eat frequent snacks, says Naturopathic Doctor Tom Ballard.
