What should I know about niedriger cortisolspiegel?

Low cortisol (hypocortisolism) may indicate adrenal insufficiency (Addison's disease, secondary insufficiency) but can also result from chronic stress, poor sleep, or corticosteroid use. Symptoms include fatigue, weight loss, low blood pressure, hyperpigmentation, and electrolyte imbalances. Diagnosis requires medical tests such as the ACTH stimulation test – over-the-counter blood or saliva tests are not sufficient. MyBody-X does not offer clinical cortisol diagnostics; DNA tests for genes like NR3C1 or CRHR1 have limited predictive value. Microbiome tests cannot reliably measure cortisol. Importantly, persistently low cortisol is a serious condition that needs medical evaluation. Lifestyle factors (stress management, regular sleep, balanced diet) can support cortisol regulation but do not replace medical treatment. Evidence: practice guidelines; no strong genetic evidence from the provided context.
