Adrenal Fatigue Test

The term "adrenal fatigue" is not an official medical diagnosis recognized by endocrinology societies. However, HPA axis dysregulation (the underlying mechanism) is well-documented and measurable via 4-point salivary cortisol testing. The conventional diagnosis for severely low cortisol is Addison disease — a rare autoimmune condition. Most people with "adrenal fatigue" symptoms have functional HPA dysregulation, not true Addison disease.

Classic low cortisol symptoms: extreme fatigue that does not improve with rest, salt and sugar cravings (especially for salty foods), dizziness when standing (orthostatic hypotension), morning fatigue with better energy in the evening, brain fog, poor stress tolerance, frequent illness, achiness, and dehydration. Distinguish from high cortisol: low cortisol typically causes AM fatigue; high cortisol causes PM fatigue and 3am waking.

Recovery from HPA axis burnout is slow: mild dysregulation: 6-9 months with lifestyle changes. Moderate: 12-18 months. Severe burnout: 18-24 months minimum. Key recovery pillars: sleep 8-9 hours (non-negotiable), eliminate or drastically reduce caffeine (depletes adrenal reserves), glycemic management (avoid blood sugar spikes), adaptogens (ashwagandha, rhodiola), and salt + water intake before noon.

Yes, temporarily. High-intensity exercise (HIIT, heavy lifting) is cortisol-stimulating — it will worsen HPA dysregulation. During recovery, replace with parasympathetic-activating activities: walking (20-30min), yoga, tai chi, slow swimming, or light cycling. Return to intense training only after 3-6 months of sustained energy improvement.
