Adrenal Fatigue Is Not A Real Disease

• Dr. Karl Nadolsky says “adrenal fatigue” as a distinct diseased state is not real and originated from a book by James Wilson.

• We have well-defined adrenal disorders: true adrenal insufficiency (serious and diagnosable) and cortisol excess like Cushing syndrome.

• Chronic stress activates the hypothalamic–pituitary–adrenal (HPA) axis and raises cortisol — which is an appropriate, protective response, not evidence the adrenals are failing.

• The claim that chronic stress makes the adrenals “wear out” is misleading; true insufficiency comes from destruction of adrenal cells and requires medical diagnosis.

• Confusing normal stress responses with disease fuels pseudoscientific treatments and distracts from diagnosing real endocrine problems.

Menopause, Thyroid, And Cortisol Are Not Sole Obesity Drivers

• Dr. Karl Nadolsky explains menopause causes only a subtle shift toward central (visceral) fat and modest weight gain, not the dramatic weight changes often advertised.

• Menopausal hormone therapy can mitigate that effect but menopause is not the primary driver of obesity.

• True hypothyroidism affects metabolic rate but alone usually does not produce obesity; it can worsen weight gain when other factors are present.

• Overall appetite and metabolic control are complex and driven more by adipose- and gut-derived hormones (e.g., leptin, GLP) and hypothalamic pathways than by sex or thyroid hormones alone.

• Cortisol becomes relevant only in clear pathological states (Cushing’s or cortisol-secreting tumors), not in the vague concept of “adrenal fatigue.”
