Physiology, Cortisol

In: StatPearls [Internet]. Treasure Island (FL): StatPearls Publishing; 2023 Jan.


Though widely known as the body’s stress hormone, Cortisol has a variety of effects on different functions throughout the body. It is the main glucocorticoid released from the zona fasciculata layer of the adrenal cortex. The hypothalamus-pituitary-adrenal axis regulates both production and secretion of cortisol. Loss of regulation can lead to cortisol excess disorders, such as Cushing syndrome, or cortical insufficiency, such as Addison disease.
