“Adrenal fatigue” is a popular term on the internet, but what does science say?
What is Adrenal Fatigue?
The idea is that chronic stress “wears out” your adrenal glands, causing fatigue, brain fog, and sleep problems. However, mainstream endocrinology does not recognize adrenal fatigue as a medical diagnosis.
What’s Really Happening?
True adrenal insufficiency (Addison’s disease) is rare and serious, diagnosed with specific tests. Most people with fatigue have other causes—sleep disorders, thyroid problems, depression, or lifestyle factors.
The Takeaway
If you’re feeling persistently tired, see your doctor for a thorough evaluation. Don’t self-diagnose or buy unproven supplements. Evidence-based medicine will always serve you best.
