What Is Adrenal Fatigue?

Adrenal fatigue — more precisely called HPA axis dysfunction or cortisol dysregulation — describes a state in which the hypothalamic-pituitary-adrenal stress axis has become dysregulated after a prolonged period of physical, emotional, or physiological stress. Rather than truly exhausted adrenal glands, it typically involves abnormal cortisol rhythm: cortisol may be low in the morning (causing fatigue and difficulty waking), high in the evening (causing insomnia), or both — a loss of the normal diurnal pattern essential for energy, mood, and immune function.

Common Symptoms

Morning fatigue — difficulty waking even after a full night's sleep
Energy that improves through the day but dips in the early afternoon
Second wind in the evening — wired and alert when you should be winding down
Difficulty recovering from illness or stress
Salt and sugar cravings
Brain fog, difficulty concentrating, and poor memory
Heightened emotional reactivity, irritability, and reduced stress tolerance
Dizziness upon standing (orthostatic hypotension from low aldosterone)

Root Causes: A Functional Medicine Perspective

The HPA axis is the body's master stress regulation system. Prolonged physical stress (illness, surgery, extreme exercise), psychological stress, or physiological stressors (poor sleep, blood sugar dysregulation, infections, gut dysfunction) chronically activate the HPA axis. Over time, the system loses its normal diurnal rhythm — high cortisol in the morning to drive alertness, low cortisol in the evening to allow sleep.

Nutritional deficiencies — particularly vitamin C, B5 (pantothenic acid), magnesium, and adrenal-supportive herbs — impair adrenal function. Thyroid dysfunction and adrenal dysfunction are closely linked — each worsens the other. Chronic inflammation from gut dysbiosis, food sensitivities, or systemic infection maintains the HPA axis in a state of chronic activation.

How We Treat Adrenal Fatigue at IHP

Dr. Hendry measures cortisol rhythm using four-point salivary cortisol testing, which captures the cortisol curve throughout the day. This objective assessment guides the specific protocol needed: low morning cortisol requires different support than high evening cortisol, and each pattern responds to different adaptogenic herbs and timing strategies.

Treatment includes: adaptogenic herbs (ashwagandha, rhodiola, eleuthero, and licorice root — selected based on cortisol pattern), adrenal nutrient support (vitamin C, B5, magnesium), blood sugar stabilization (to prevent the cortisol spikes triggered by hypoglycemia), sleep optimization, and stress management strategies. Acupuncture regulates the HPA axis through hypothalamic and pituitary modulation, helping normalize the cortisol rhythm.

Dr. Hendry's Approach

Dr. Hendry views adrenal dysfunction as the body's rational response to unsustainable demand — a signaling problem, not an organ failure. His approach addresses both the biological restoration of HPA rhythm and the lifestyle factors that initially dysregulated it, creating both immediate symptom relief and long-term stress resilience.

Frequently Asked Questions About Adrenal Fatigue

The term 'adrenal fatigue' is not in the conventional medical lexicon, but HPA axis dysregulation and abnormal cortisol rhythms are documented and measurable. Functional medicine testing (salivary cortisol rhythm) identifies dysregulated patterns that standard blood cortisol tests (taken at a single morning time point) miss.
Adaptogens are a class of herbs that help the body adapt to stress by modulating the HPA axis. Ashwagandha lowers chronically elevated cortisol and improves the cortisol awakening response. Rhodiola improves energy and stress resilience. Licorice root prolongs the active half-life of cortisol (useful for low morning cortisol patterns). Selection depends on each patient's specific cortisol pattern.
Mild HPA dysregulation typically improves within 2–3 months of targeted treatment. More significant dysregulation after years of chronic stress may require 6–12 months of sustained support. The timeline also depends on how well the underlying stressors are addressed.
High-intensity exercise acts as an additional stressor on an already taxed HPA axis and can worsen adrenal dysregulation. Gentle exercise (walking, yoga, swimming) supports recovery. Intensity is gradually restored as the HPA axis normalizes and energy levels improve.
Adrenal cortisol is essential for T4-T3 thyroid hormone conversion. Low cortisol impairs thyroid conversion, producing functional hypothyroid symptoms even with normal thyroid labs. Conversely, hypothyroidism stresses the adrenal system. These two systems must often be treated simultaneously for full recovery.
