Question 1

What is the Meaning of Stress Hormone?

Accepted Answer

"Stress hormone" refers to biochemical messengers, primarily cortisol and catecholamines like adrenaline and noradrenaline, released by the endocrine system in response to physiological or psychological stressors. These substances orchestrate the body's adaptive responses, preparing an individual to confront or evade perceived threats.

Question 2

What is the Context of Stress Hormone?

Accepted Answer

Stress hormones function as integral components of the neuroendocrine system, primarily originating from the adrenal glands. Cortisol production is regulated by the HPA axis. Catecholamines are synthesized in the adrenal medulla and sympathetic nervous system, working in concert to manage physiological demands.

Question 3

What is the Significance of Stress Hormone?

Accepted Answer

The clinical significance of stress hormones is substantial; their balanced regulation is vital for homeostatic equilibrium and overall health. Dysregulation, whether excessive or insufficient, can contribute to clinical presentations like chronic fatigue, metabolic syndrome, impaired immune function, and mood disturbances, serving as key indicators in diagnostic assessments and treatment planning.

Question 4

What is the Mechanism of Stress Hormone?

Accepted Answer

Stress hormones exert effects by binding to specific receptors on target cells. Cortisol, a steroid, interacts with intracellular glucocorticoid receptors, influencing gene transcription to modulate glucose metabolism, suppress inflammation, and regulate blood pressure. Catecholamines bind to adrenergic receptors, rapidly increasing heart rate, dilating airways, and mobilizing energy stores.

Question 5

What is the Application of Stress Hormone?

Accepted Answer

In clinical practice, understanding stress hormone dynamics is foundational for managing adrenal dysfunction, such as Addison's disease or Cushing's syndrome, and chronic stress-related health challenges. Clinicians use stress hormone profiles for personalized treatment strategies, including pharmacotherapy, lifestyle modifications, and stress reduction, aiming to restore physiological balance and improve patient well-being.

Question 6

What is the Metric of Stress Hormone?

Accepted Answer

Assessment of stress hormone levels involves specific biochemical assays in biological fluids. Serum cortisol levels are frequently measured, often with multiple samples for diurnal variation. Salivary cortisol tests offer a convenient method for assessing unbound hormone. Urinary collections provide insight into cumulative hormone excretion. Plasma or urinary metanephrines evaluate catecholamine activity, aiding diagnosis and monitoring.

Question 7

What is the Risk of Stress Hormone?

Accepted Answer

Improper management or sustained dysregulation of stress hormones carries significant clinical risks. Chronically elevated levels, seen in prolonged stress or Cushing's syndrome, can precipitate metabolic derangements like hyperglycemia, central obesity, and hypertension, alongside immune suppression and bone demineralization. Conversely, insufficient stress hormone production, as in adrenal insufficiency, can lead to severe fatigue, electrolyte imbalances, hypotension, and adrenal crisis.
