What is the Origin of Glucocorticoid Interference?

The term stems from the combined fields of endocrinology and pharmacology, recognizing the broad, pleiotropic effects of cortisol and synthetic glucocorticoids across multiple body systems. The concept emphasizes the hierarchical dominance of the stress axis over other homeostatic systems.

What is the Mechanism of Glucocorticoid Interference?

Glucocorticoids interfere by binding to their widely distributed intracellular receptors, which then act as transcription factors to alter the expression of numerous genes. At a molecular level, high cortisol can directly inhibit the pulsatile release of Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH), thereby suppressing the gonadal axis. Furthermore, it impairs insulin signaling and disrupts the conversion of inactive to active thyroid hormone, creating systemic hormonal imbalance.

Glucocorticoid Interference

Meaning

Glucocorticoid interference describes the negative physiological impact that excessive or inappropriately timed levels of glucocorticoid hormones, primarily cortisol, exert on other endocrine axes and metabolic processes. This interference can suppress immune function, inhibit anabolic hormone action, and contribute to insulin resistance. Recognizing and mitigating this interference is a core clinical objective in managing chronic stress and adrenal dysregulation.
