Explain how the stress response alters glucose metabolisn

Stress triggers the release of catabolic hormones: adrenaline, noradrenaline, glucagon and cortisol. Adrenaline, glucagon and noradrenaline all work synergistically to promote glycogenolysis in the liver, which increases BGL. Cortisol promotes gluconeogenesis, lipolysis, and increases insulin resistance leading to a decrease in cellular uptake of glucose. As a result of all these physiologic changes, the patient may become hyperglycaemic.
