Addison Disease (Primary Adrenal Insufficiency)

★ CMTO Exam Focus

Addison disease is chronic primary adrenal insufficiency caused by progressive destruction of the adrenal cortex, resulting in deficient production of cortisol, aldosterone, and adrenal androgens. It is the functional opposite of Cushing syndrome. Autoimmune adrenalitis accounts for 70-90% of cases in developed countries. Massage therapists must understand Addison disease because clients are vulnerable to adrenal crisis — a life-threatening emergency triggered by physiologic stress — and their tissue fragility, profound fatigue, and hemodynamic instability require significant treatment modification.

Populations and Risk Factors

  • Autoimmune adrenalitis (most common cause in developed countries — 70-90% of cases)
  • Women more commonly affected than men (approximately 2:1)
  • Peak onset ages 30-50
  • Strong association with other autoimmune conditions: Hashimoto thyroiditis, type 1 diabetes, vitiligo, pernicious anemia, celiac disease (autoimmune polyendocrine syndrome types I and II)
  • Tuberculosis (most common cause in developing countries — adrenal gland destruction)
  • Adrenal hemorrhage (anticoagulant therapy, sepsis — Waterhouse-Friderichsen syndrome in meningococcemia)
  • Metastatic cancer to the adrenals (lung, breast, melanoma)
  • Abrupt withdrawal of long-term exogenous corticosteroids causes secondary adrenal insufficiency (the most common overall cause of adrenal insufficiency, though this is distinct from primary Addison disease)

Causes and Pathophysiology

  • Autoimmune destruction: Cytotoxic T lymphocytes progressively destroy all three zones of the adrenal cortex (zona glomerulosa, fasciculata, reticularis). Symptoms manifest only when 90% or more of the cortex is destroyed, meaning the disease is advanced by the time of diagnosis.
  • Cortisol deficiency: Impairs the stress response (inability to mount appropriate cortisol surge during illness, surgery, or trauma), causes hypoglycemia (impaired gluconeogenesis), fatigue, weight loss, and nausea. Without cortisol, the body cannot maintain vascular tone or mobilize energy reserves under stress.
  • Aldosterone deficiency: Sodium wasting and potassium retention (hyperkalemia — cardiac arrhythmia risk), hypovolemia from sodium and water loss, and chronic hypotension. The resulting dehydration and electrolyte imbalance are life-threatening if untreated.
  • ACTH elevation and hyperpigmentation: Loss of cortisol negative feedback causes the pituitary to increase ACTH secretion. ACTH is cleaved from the same precursor molecule (proopiomelanocortin/POMC) as melanocyte-stimulating hormone (MSH). Elevated MSH causes the hallmark bronze hyperpigmentation, particularly in skin creases, scars, buccal mucosa, and areolae. This distinguishes primary from secondary adrenal insufficiency (secondary lacks hyperpigmentation because ACTH is low).
  • Adrenal crisis (Addisonian crisis): Acute cortisol depletion triggered by physiologic stress (illness, surgery, trauma, emotional distress) in a client whose adrenal glands cannot increase cortisol production. Presents as severe hypotension, circulatory shock, altered consciousness — fatal without immediate IV hydrocortisone and fluid resuscitation.

Signs and Symptoms

  • Hyperpigmentation of skin and mucous membranes — hallmark and pathognomonic (uniquely characteristic of this disease) sign. Most pronounced in skin creases, palmar creases, scars, buccal mucosa, areolae, and pressure points
  • Progressive fatigue, weakness, and malaise (often the chief complaint)
  • Weight loss and anorexia
  • Orthostatic hypotension and dizziness (often severe)
  • Salt craving (aldosterone deficiency drives sodium loss)
  • Nausea, vomiting, abdominal pain
  • Hypoglycemia (especially between meals or after exercise)
  • Myalgia and arthralgia
  • Adrenal crisis: Sudden severe hypotension, tachycardia, dehydration, confusion, nausea/vomiting, loss of consciousness

Red Flags

  • Adrenal crisis signs: Severe hypotension, confusion, nausea/vomiting, collapse — call 911; administer client's emergency hydrocortisone injection if available and you are trained to do so
  • Client appears unusually fatigued, confused, or hypotensive: Consider whether they may be entering crisis — ask about medication compliance and recent illness
  • Client has not taken their hydrocortisone dose: Session should be postponed until medication is taken

MT Considerations

  • Stress reduction is particularly valuable: Physiologic stress is a crisis trigger. Relaxation massage directly supports adrenal stability
  • Vigorous techniques that impose physiologic stress should be avoided: Deep tissue, aggressive neuromuscular therapy, and prolonged intense sessions can act as physiologic stressors in cortisol-deficient clients
  • Orthostatic hypotension: Often severe — slow position transitions are mandatory. Monitor for dizziness, lightheadedness, or near-syncope during repositioning.
  • Blood pressure: Monitor before and after sessions. Hypotension is baseline for these clients.
  • Hypoglycemia prevention: Have the client eat before the session. Keep glucose tablets or juice available
  • Temperature regulation: Keep the treatment room warm — poor thermoregulation is common
  • Session intensity and duration: Moderate intensity, moderate duration — fatigue is chronic
  • Emergency preparedness: Ask whether the client carries emergency hydrocortisone (injectable or oral stress dose) and know where it is. Familiarize yourself with the client's emergency action plan.
  • Medications: Standard replacement is hydrocortisone (cortisol) twice daily plus fludrocortisone (aldosterone analog). Clients must "stress dose" (double or triple hydrocortisone) during illness, surgery, or significant physiologic stress. Confirm they have taken their dose on the day of treatment.
  • Autoimmune cluster: Often coexists with Hashimoto thyroiditis, type 1 diabetes, vitiligo, and pernicious anemia — screen for and manage concurrent conditions

CMTO Exam Relevance

  • Category: A7 Systemic Conditions — Endocrine
  • Addison disease is the functional opposite of Cushing syndrome — distinguish by presentation (hyperpigmentation, hypotension, and salt craving vs. moon face, hypertension, and central obesity)
  • Hyperpigmentation is pathognomonic for primary adrenal insufficiency — its absence suggests secondary (pituitary) insufficiency
  • Adrenal crisis as a medical emergency — know the signs and immediate actions
  • Orthostatic hypotension management and slow position transitions
  • Autoimmune polyendocrine syndrome — recognize the cluster pattern

Key Takeaways

  • Addison disease results from progressive adrenal cortex destruction, usually autoimmune, requiring 90% destruction before symptoms appear
  • Hyperpigmentation (especially skin creases and scars) is the hallmark sign — distinguishes primary from secondary adrenal insufficiency
  • Adrenal crisis is life-threatening and triggered by physiologic stress — massage therapists should know crisis signs and emergency protocols
  • Orthostatic hypotension is common and often severe — slow position changes are mandatory
  • Relaxation massage is valuable because stress reduction directly supports adrenal stability
  • Often coexists with other autoimmune conditions (Hashimoto, type 1 diabetes, vitiligo, pernicious anemia)
