Adrenal Fatigue: When Your Stress Response Is Exhausted
"Adrenal fatigue" isn't a medical diagnosis, but the symptoms are very real. The more accurate term is HPA axis dysfunction — and understanding it is the key to recovery.

What Is "Adrenal Fatigue"?
Your HPA axis (hypothalamus-pituitary-adrenal) controls your stress response and cortisol production. When chronically activated by stress, it can become dysregulated.
The term "adrenal fatigue" describes a state of chronic exhaustion and stress intolerance. While conventional medicine doesn't recognize it as a diagnosis, functional practitioners recognize the underlying pattern: HPA axis dysfunction — producing too much cortisol, too little, or in the wrong patterns.
Warning Signs of HPA Dysfunction
Caffeine Dependence
Needing coffee just to function is a classic sign. Caffeine masks the problem while depleting reserves.
Reversed Cortisol
Low cortisol in the morning (can't wake up) and high at night (can't sleep) is a hallmark pattern.
Energy Rollercoaster
Alternating between crashes and brief energy bursts, often driven by stimulants or sugar.
Emotional Fragility
Reduced stress tolerance, easy overwhelm, or feeling like you're "running on fumes."
Common Symptoms
The 3 Stages of HPA Dysfunction
Alarm (High Cortisol)
Initial stress response. Cortisol is elevated. You feel wired, anxious, may have trouble sleeping. Energy is still available but you're running on stress hormones.
Resistance (Dysregulated Cortisol)
The body struggles to keep up. Cortisol may be high at some times, low at others. You start feeling tired but can't relax.
Exhaustion (Low Cortisol)
The HPA axis can no longer maintain adequate cortisol output. Profound fatigue, low blood pressure, inability to handle any stress.
Important Distinction
True adrenal insufficiency (Addison's disease) is a serious medical condition requiring hormone replacement. HPA dysfunction is different — it's about dysregulation, not failure. If you have severe symptoms, see a doctor to rule out medical conditions.
Root Causes
Chronic Stress
The primary driver — emotional, physical, or psychological
Sleep Deprivation
Cortisol regulation depends on quality sleep
Blood Sugar Instability
Low blood sugar triggers cortisol release
Chronic Inflammation
From gut issues, food sensitivities, or illness
Over-Exercise
Excessive training without adequate recovery
Stimulant Overuse
Caffeine depletes adrenal reserves over time
6 Keys to Recovery
Address the Stressors
You can't supplement your way out of a stressful life. Identify and reduce sources of chronic stress. This is the foundation — without it, other interventions will have limited effect.
Prioritize Sleep
Be in bed by 10pm. Cortisol naturally rises around 11pm — catching sleep before this supports recovery. Aim for 8-9 hours during the healing phase.
Stabilize Blood Sugar
Eat protein with every meal. Avoid blood sugar crashes that trigger cortisol spikes. Don't skip meals — fasting is stressful for depleted adrenals.
Reduce Stimulants
Gradually wean off caffeine. It masks symptoms while depleting reserves. Replace with adaptogenic teas or decaf alternatives during recovery.
Gentle Movement Only
Intense exercise stresses the adrenals. Walk, do yoga, or rest until energy improves. Exercise should energize you — if it exhausts you, you're doing too much.
Adapt and Restore
Adaptogenic herbs support HPA axis balance and stress resilience:
