Insulin release is inhibited by increased corticosteroid levels, as well as by a direct cooling
effect on the islets of Langerhans;in addition, peripheral uptake of insulin at the tissues is impaired.
and the catecholamine-induced glycogenolysis
and gluconeogenesis contribute to the hyperglycaemia.
The glucagon level is increased, and
plasma cortisol levels correlate with lactate and
glycerol levels, implying active stimulation of glycogenolysis
and lipolysis
