The elevated level of cortisol which is a steroid hormone, results from increased synthesis of cortisol in the adrenal glands. Cortisol is synthesized from a substrate called, cholesterol. Cortisol synthesis occurs in the zona fasciculata of the adrenal cortex and controlled or regulated by the hypothalamus-pituitary-adrenal axis or HPA axis.
