Why epinephrine induce an elevation in glycemia?

Epinephrine induces an elevation in glycemia primarily by promoting glycogenolysis and gluconeogenesis in the liver, which increases glucose release into the bloodstream. It stimulates the breakdown of glycogen into glucose and enhances the production of glucose from non-carbohydrate sources. Additionally, epinephrine inhibits insulin secretion and promotes lipolysis, further contributing to increased blood sugar levels. This response is part of the body's "fight or flight" mechanism, providing the necessary energy for immediate physical activity.
