Adrenal Fatigue / HPA Axis Dysfunction
A controversial term for fatigue attributed to stressed adrenal glands.
Overview
"Adrenal fatigue" is a popular but medically controversial term describing fatigue and other symptoms supposedly caused by poorly functioning adrenal glands after chronic stress. While mainstream medicine doesn't recognize "adrenal fatigue" as a diagnosis (the adrenals don't simply "tire out"), the symptoms are real. The more accurate concept is HPA (hypothalamic-pituitary-adrenal) axis dysregulation, where chronic stress disrupts cortisol patterns. True adrenal insufficiency (Addison's disease) is a serious but different condition.

Detailed Treatment & Solutions
1STRESS REDUCTION
This is the core treatment. Meditation, yoga, deep breathing. Reduce commitments. Set boundaries. Therapy for stress management and underlying issues.
2SLEEP OPTIMIZATION
Aim for 8+ hours. Consistent schedule. Good sleep hygiene. Address any sleep disorders. Sleep is when adrenals and HPA axis recover.
3BLOOD SUGAR STABILITY
Eat regular meals with protein, fat, and complex carbs. Avoid sugar spikes and crashes. Don't skip meals. Reduce refined carbohydrates.
4GENTLE EXERCISE
Moderate activity supports recovery. Avoid intense exercise which can stress HPA axis further. Walking, yoga, swimming are good choices.
5MEDICAL EVALUATION
See a doctor to rule out real conditions: thyroid disorders, anemia, sleep apnea, depression, true adrenal insufficiency. Don't self-diagnose.
6EVIDENCE-BASED SUPPORT
Some adaptogenic herbs (ashwagandha, rhodiola) have modest evidence for stress support. Avoid expensive "adrenal support" supplement stacks without evidence.

Frequently Asked Questions
QIs adrenal fatigue a real diagnosis?
Mainstream medical organizations don't recognize "adrenal fatigue" as a diagnosis. The adrenal glands don't simply "tire out." However, the symptoms people experience are real. They're better explained by HPA axis dysregulation from chronic stress, or by other conditions like thyroid disorders, depression, or sleep problems that should be properly evaluated.
QShould I take adrenal supplements?
Be cautious. Many "adrenal support" products are expensive and lack evidence. Some contain actual adrenal hormones which can be dangerous. If considering supplements, discuss with a doctor. Focus first on stress reduction, sleep, and ruling out treatable conditions.
