What Is Adrenal Fatigue?
'Adrenal fatigue' is a contested term — not an accepted medical diagnosis, but describing a real experience of persistent fatigue, low stress tolerance, and poor morning energy that many people associate with chronic stress. The underlying physiology is real even if the label is debated.
What adrenal fatigue describes
The cluster of symptoms attributed to adrenal fatigue — fatigue especially in the morning, low stress tolerance, salt cravings, difficulty recovering from illness, reliance on stimulants — does exist and is experienced by many people after periods of prolonged stress. The debate is whether the adrenal glands themselves are 'fatigued' or whether the issue lies upstream in the HPA axis regulation.
The medical establishment recognises Addison's disease (primary adrenal insufficiency) as a genuine and serious condition, and subclinical HPA axis dysregulation as a real but difficult-to-measure state. Most people who identify with 'adrenal fatigue' fall into the latter category.
HPA axis dysregulation and cortisol patterns
Chronic stress initially produces elevated cortisol; over prolonged periods, the HPA axis can become dysregulated, producing an abnormal diurnal cortisol curve — low in the morning (blunted cortisol awakening response), higher in the evening when it should be falling. This inversion of the normal cortisol pattern explains the morning sluggishness and evening wired-ness that many 'adrenal fatigue' sufferers describe.
Measuring salivary cortisol at four points through the day (morning, noon, afternoon, evening) via a private lab test can characterise your cortisol pattern and guide targeted intervention.
Recovery approaches
Recovery focuses on stress load reduction, sleep optimisation, blood sugar stabilisation, and targeted supplementation. Ashwagandha has good evidence for reducing cortisol and improving fatigue in chronically stressed individuals. Rhodiola rosea has similar evidence for reducing fatigue and improving resilience.
The most important intervention is reducing the chronic stress load itself — supplements and lifestyle tweaks won't overcome sustained HPA axis overactivation if the underlying stressors remain unchanged.
Our assessment evaluates your stress patterns and energy curve to identify HPA axis dysregulation as a potential fatigue contributor.
Frequently Asked Questions
What are the symptoms of adrenal fatigue?
Symptoms of adrenal fatigue include persistent fatigue, low stress tolerance, morning sluggishness, salt cravings, and difficulty recovering from illness.
Is adrenal fatigue a recognized medical condition?
Adrenal fatigue is not an accepted medical diagnosis, but it describes a cluster of symptoms that many people experience after prolonged stress.
How can I test my cortisol levels for adrenal fatigue?
You can measure your cortisol levels by taking a salivary cortisol test at four points throughout the day, which can help characterize your cortisol pattern.
What are effective treatments for adrenal fatigue?
Effective treatments focus on reducing stress, optimizing sleep, stabilizing blood sugar, and may include supplements like ashwagandha and rhodiola rosea.
