Question 1

What is the Meaning of Cortisol and Allostatic Load?

Accepted Answer

Cortisol is the primary glucocorticoid hormone released by the adrenal glands in response to activation of the hypothalamic-pituitary-adrenal (HPA) axis, functioning to mobilize energy and suppress non-essential systems during stress. Allostatic load is the cumulative physiological wear and tear on the body that results from chronic, repeated efforts to adapt to stressors. When the stress response is repeatedly activated or fails to shut off, the sustained exposure to cortisol and other stress mediators drives this allostatic load, leading to systemic dysregulation and increased disease risk.

Question 2

What is the Origin of Cortisol and Allostatic Load?

Accepted Answer

Cortisol's role as a stress hormone was established by Hans Selye's foundational work on the General Adaptation Syndrome in the 1930s. The concept of allostatic load was later introduced by McEwen and Stellar to describe the long-term, damaging consequences of chronic stress and the cost of maintaining physiological stability, or allostasis. This clinical framework moved beyond simple acute stress response to account for the systemic, long-term impact of life demands on the endocrine and cardiovascular systems. It is a vital tool for assessing biological aging and disease vulnerability.

Question 3

What is the Mechanism of Cortisol and Allostatic Load?

Accepted Answer

Chronic psychosocial or physical stress leads to prolonged or excessive secretion of cortisol. High cortisol acts on mineralocorticoid and glucocorticoid receptors throughout the body, driving mechanisms that contribute to allostatic load. These mechanisms include promoting visceral fat deposition, suppressing immune function, increasing blood glucose, and directly inhibiting the reproductive axis. The resulting physiological imbalance, particularly the loss of the normal diurnal cortisol rhythm, accelerates cellular damage and contributes to metabolic and hormonal disorders.
