Is Low Cortisol a Marker of Long COVID?

Cortisol is the primary glucocorticoid hormone produced by the adrenal glands, playing a critical role in multiple physiological processes, including metabolism, immune response regulation, cardiovascular regulation, and the body's stress response1. The secretion of cortisol is closely regulated by the hypothalamus-pituitary-adrenal (HPA) axis. The process is initiated by the release of corticotropin-releasing hormone (CRH) from the hypothalamus, which stimulates the production of adrenocorticotropic hormone (ACTH) by the pituitary gland.
