Adrenal Dysfunction

The wellness industry uses \u0027adrenal dysfunction\u0027 or \u0027adrenal fatigue\u0027 to explain nonspecific symptoms — fatigue, brain fog, salt craving, poor stress tolerance — attributing them to exhausted adrenal glands. The problem is that the construct fails testing: a 2016 systematic review of 58 studies found no consistent cortisol abnormality in people labeled with adrenal fatigue, and the condition is not recognized by endocrinology societies. Salivary \u0027adrenal panels\u0027 sold direct-to-consumer lack validated reference ranges and reproducibility.\n\nThis matters in two directions. First, the label delays diagnosis of the real and common causes of fatigue: sleep apnea, depression, iron deficiency, hypothyroidism, diabetes, and medication effects. Second, it drives use of adrenal glandulars — which may contain actual hormones — and inappropriate hydrocortisone, which can suppress a healthy hypothalamic-pituitary-adrenal axis and cause genuine dependence.\n\nThe symptoms are real even if the explanation is not. Chronic stress does dysregulate physiology — sleep, appetite, immune function — and evidence-based management targets sleep regularity, exercise, psychological treatment, and treatment of any actual deficiency found on a proper workup. True adrenal disease exists (Addison\u0027s, Cushing\u0027s) and is diagnosed with validated testing, not symptom checklists.

• •Persistent fatigue despite sleep
• •Brain fog and poor concentration
• •Feeling \u0027wired but tired\u0027
• •Salt or sugar cravings
• •Afternoon energy crashes
• •Low stress tolerance

• •No validated adrenal pathology — symptoms usually reflect:
• •Chronic stress and sleep deprivation
• •Undiagnosed sleep apnea
• •Depression or anxiety
• •Iron deficiency, hypothyroidism, or diabetes
• •Medication effects and overtraining
