HPA-Axis Dysregulation (often called "adrenal fatigue")
"Adrenal fatigue" is not a recognized diagnosis. The Endocrine Society and a 2016 systematic review found no evidence for it. TOBIN uses the term HPA-axis dysregulation for stress-related fatigue, poor sleep and low resilience, where the adrenal glands themselves are not failing. The priority is to rule out real adrenal disease. Morning serum cortisol below 3 µg/dL strongly suggests adrenal insufficiency, and a value of 15 µg/dL or more makes it unlikely (Endocrine Society 2016). Values in between need an ACTH stimulation test. Late-night salivary cortisol above the lab's limit screens for Cushing's syndrome.
Domain weighting
Organizational emphasisiWeightings describe where this framework directs attention for this condition. They are not a measure of how much any factor caused an individual case.
Root-cause chain
Each link carries its own evidence grade- Chronic psychological stress→Altered cortisol rhythmBB
Flattened diurnal cortisol slope associates with chronic stress and fatigue in cohort studies.
Relationship: Observational association
- Short or irregular sleep→Fatigue and higher evening cortisolOB
Sleep restriction raises evening cortisol in controlled studies.
Relationship: Randomized evidence
- Stopping long-term steroids→True adrenal insufficiencyBA
Exogenous glucocorticoids suppress ACTH; abrupt withdrawal can cause adrenal crisis.
Relationship: Established causal
- Commercial "adrenal" supplements→Hidden thyroid or steroid hormonesTB
Kalra 2018 found thyroid hormone and steroids in most tested adrenal-support products.
Relationship: Exposure signal
iDetection of an exposure does not establish that it caused a disease. This platform separates exposure, association, plausible mechanism, clinical evidence and demonstrated causation.
Fifth Estate considerations
Microbial ecologyNo infection causes "adrenal fatigue". Tuberculosis and fungal infection are rare causes of true adrenal insufficiency.

Six lanes · evidence grade and regulatory status on every entryConventional
Endocrine Society: adrenal fatigue is not a diagnosis; treat any condition actually found.
Caution: Do not start hydrocortisone without proven adrenal insufficiency.
Functional
CBT-I is first-line for chronic insomnia (ACP guideline).
Caution: Screen for sleep apnea.
Integrative
Meta-analyses show reduced stress and anxiety. Effect on cortisol is small.
Caution: Not a substitute for depression care.
Orthomolecular
Treats proven causes of fatigue.
Caution: Treat measured deficiencies only.
Traditional
Small RCTs show lower perceived stress and cortisol.
Caution: Rare liver injury; avoid in pregnancy, hyperthyroidism and with sedatives. Avoid "adrenal glandular" products, which may contain hidden hormones.
Energy / Physical
Energy medicine on Tayapulse →Small trials show reduced stress; evidence is limited.
Caution: Adjunct only.
iLanes are presented side by side so the difference in evidence strength is visible. Nothing here is a prescription, and interactions must be reviewed with your clinician and pharmacist.
iEnergy and physical modalities in this lane are explored further with Tayapulse. Evidence grade and regulatory status still apply: these are adjuncts used only where indicated, never cures or replacements for guideline care.
Diagnostics to consider
- · Morning (8 am) serum cortisol with ACTH
- · ACTH stimulation test when cortisol is 3–15 µg/dL
- · Late-night salivary cortisol (Cushing's screen)
- · TSH, ferritin, B12, CBC (other causes of fatigue)
- · PHQ-9 / GAD-7 and sleep history
Monitoring
- · Fatigue, sleep and mood in the daily journal
- · Repeat cortisol only if symptoms change
- · TOBIN score change over time
Prevention emphasis
- · Regular sleep-wake schedule
- · Regular physical activity
- · Stress-management skills
- · Never stop prescribed steroids abruptly
