TL;DR
Why persistent tiredness requires structured workup across sleep, hormones, metabolism, and recovery load.
Fatigue has many doors
Chronic fatigue can stem from sleep apnea, iron deficiency, thyroid disease, depression, insulin resistance, medication effects, or simple overtraining. Treating one guess often fails.
A clinical differential starts with history, sleep screening, and targeted labs rather than stimulants or unverified protocols.
What good workup includes?
Common elements include CBC, ferritin, B12, thyroid panel, metabolic markers, and sometimes cortisol or sleep studies. Athletes add training load and recovery metrics.
Symptom clusters guide order of testing. There is no universal fatigue panel for every person.
Energy pathway entry
Eterna IQ maps fatigue to the energy and recovery pathway with coaching and re-measurement. Prescription support may follow clinician review when appropriate.
Educational only. Sudden severe fatigue or weight loss warrants prompt medical evaluation.
