A common myth is that a single hormone test (e.g., saliva or blood) can definitively diagnose the cause of fatigue. The fact is that fatigue is multifactorial – sleep, stress, nutrition, thyroid function, iron deficiency, and psychological factors all contribute. Hormonal fluctuations (estrogen, progesterone, cortisol) can play a role, but a single measurement is rarely conclusive because hormones vary diurnally and across the menstrual cycle. Genetic variants (e.g., in VDR or COMT genes) have small effect sizes and are not direct evidence of hormonal dysfunction causing fatigue. The evidence linking such variants to fatigue is weak (mechanistic, not clinically validated). A hormone check can provide orientation but does not replace medical workup.
