Question 1

What is the Meaning of Cortisol-to-DHEAS Ratio?

Accepted Answer

The Cortisol-to-DHEAS Ratio is a significant clinical metric that quantifies the relationship between the circulating levels of the catabolic stress hormone cortisol and the anabolic adrenal androgen dehydroepiandrosterone sulfate (DHEAS). This ratio serves as a reliable indicator of adrenal gland balance and the body's overall allostatic load, reflecting the dynamic tension between catabolic and anabolic processes within the endocrine system. Clinically, a persistently elevated ratio often suggests a state of chronic stress, HPA axis dysregulation, or a significant metabolic shift toward catabolism, which can negatively impact immune function and longevity. Monitoring this specific ratio provides a valuable, integrated tool for assessing endocrine resilience and the systemic impact of various lifestyle factors.

Question 2

What is the Origin of Cortisol-to-DHEAS Ratio?

Accepted Answer

The foundational concept of comparing cortisol and DHEAS emerged from in-depth research into adrenal physiology, recognizing that both hormones share a common biosynthetic origin in the adrenal cortex but exhibit fundamentally opposing primary biological actions. DHEAS is frequently considered a crucial buffer against the potentially detrimental effects of sustained high cortisol exposure. The ratio subsequently gained considerable clinical significance in stress research and longevity medicine as a practical proxy for assessing the critical balance between the adrenal gland's stress-response output and its metabolic reserve capacity.

Question 3

What is the Mechanism of Cortisol-to-DHEAS Ratio?

Accepted Answer

Both cortisol and DHEAS are synthesized from the common precursor cholesterol within the adrenal cortex, but their production follows divergent, enzyme-driven pathways. Cortisol's primary mechanism is catabolic, promoting energy mobilization and suppressing inflammatory responses via the glucocorticoid receptor. DHEAS, conversely, functions as a pro-hormone with distinct neuroprotective and immune-modulating properties. The ratio's functional mechanism reflects the preferential enzymatic utilization of steroidogenic precursors toward either the glucocorticoid or the androgen pathway, offering precise insight into the overall metabolic demands and functional status placed upon the adrenal system.
