What is the Origin of Cortisol and Metabolic Markers?

The concept is rooted in the physiological understanding of the hypothalamic-pituitary-adrenal (HPA) axis and the fundamental role of glucocorticoids in regulating energy metabolism, first extensively studied in the mid-20th century. Cortisol's counter-regulatory effects on insulin were recognized early on, establishing its profound influence on glucose utilization. The modern clinical focus links chronic HPA axis dysregulation to prevalent wellness issues.

What is the Mechanism of Cortisol and Metabolic Markers?

Cortisol exerts its metabolic influence primarily by promoting gluconeogenesis in the liver and inhibiting peripheral glucose uptake by muscle and adipose tissue, thereby increasing circulating blood glucose levels. This sustained hyperglycemia necessitates higher insulin secretion, leading to hyperinsulinemia and eventually insulin resistance. Furthermore, cortisol promotes the redistribution of fat to the visceral depots, altering adipokine secretion and exacerbating systemic inflammation, which negatively affects the lipid panel.

Cortisol and Metabolic Markers

Meaning

This term describes the clinically significant relationship between cortisol, the primary glucocorticoid stress hormone, and various indicators of metabolic health, including blood glucose, insulin sensitivity, and lipid profiles. Chronic elevation of cortisol disrupts metabolic homeostasis, leading to adverse shifts in these markers. This connection is central to understanding the physiological impact of stress on the development of conditions like metabolic syndrome and central adiposity.
