What is the Origin of Stress Hormone Profile?

The concept is foundational to endocrinology and stress physiology, stemming from the pioneering work that established the HPA axis as the primary neuroendocrine pathway for adaptation to stress. The clinical utility of measuring the profile—rather than a single, static measurement—arose from the understanding that cortisol's crucial function is defined by its characteristic diurnal fluctuation. The profile's interpretation guides interventions for stress-related conditions.

What is the Mechanism of Stress Hormone Profile?

When the body perceives a stressor, the hypothalamus releases corticotropin-releasing hormone (CRH), which stimulates the pituitary to release adrenocorticotropic hormone (ACTH). ACTH then signals the adrenal glands to produce cortisol. The profile tracks this output, revealing patterns such as a flattened diurnal curve or elevated nighttime cortisol, which indicate chronic HPA axis dysregulation. Optimal function is characterized by a robust morning peak and a sharp decline toward evening.

Stress Hormone Profile

Meaning

A comprehensive laboratory assessment that quantifies the circulating concentrations and diurnal rhythm of key hormones involved in the body’s stress response, primarily cortisol, dehydroepiandrosterone (DHEA), and catecholamines. This profile provides a clinical snapshot of the functional status of the Hypothalamic-Pituitary-Adrenal (HPA) axis, which is the central mediator of the stress response. Analysis of this profile is essential for diagnosing adrenal fatigue, chronic stress, and HPA axis dysregulation.
