Nettet12. mai 2024 · High cortisol signals the liver to release glucose into the bloodstream. At the same time, cortisol decreases insulin production by the beta cells of the pancreas thus resulting in high blood sugar. In the muscle tissue, cortisol impairs the action of insulin by decreasing glucose uptake in the muscle while enhancing insulin action in adipose ...
