Chronically elevated levels can indeed contribute to health issues like visceral obesity and immune suppression, but most individuals maintain normal, fluctuating cortisol levels. Direct-to-consumer tests (saliva, hair, or blood) often lack the standardization and clinical context needed for accurate interpretation. A single measurement is unreliable due to diurnal variation and confounding factors (sleep, exercise, diet, psychological stress). Therefore, claims that a DNA variant or a single biomarker result directly causes cortisol dysregulation are often overstated.
