The biochemical changes associated with stress clearly reflect the body’s shift into fight or flight mode and the mobilization of resources to fuel this response. It is important to resolve the changes that take place during acute stress and support the changes that can occur with prolonged stress and exhaustion Healthy lifestyle changes can factor into both stages.

A biomarker reflects underlying physiology and reflects either homeostasis or dysfunction. Blood chemistry biomarkers that reflect HPA axis activity and the physiological stress response include cortisol and DHEA/DHEA-S, corticotropin releasing hormone (CRH), adrenocorticotropic hormone (ACTH), anti-diuretic hormone (also known as vasopressin or arginine vasopressin), epinephrine, norepinephrine, and aldosterone. Prolonged stress can also prolong disruption to the HPA axis and promote metabolic and cardiovascular consequences.[1]

Recognition of the patterns associated with acute or chronic stress may help address which phase of the stress response an individual is experiencing. Note the biomarker shifts as one transitions from acute to chronic stress:

Ultimately, stress manifests as an increase in blood glucose, blood pressure, heart rate, cardiac contractility, and pupil dilation, and a decrease in gastrointestinal function. Prolongation of this sympathetic nervous system activation can become detrimental and damage tissues and organs.[3]
