Adrenaline’s Paradox – A Fight for Flight in Addison’s Disease

January 13, 2024by Dr. S. F. Czar0

Case Study: 

Patient: Sarah, a 42-year-old woman with a five-year history of fatigue, weight loss, and dizziness.

Presenting Symptoms:
  • Constant fatigue and muscle weakness, interfere with daily activities.
  • Weight loss despite adequate diet.
  • Recurrent episodes of dizziness and lightheadedness, especially upon standing.
  • Skin hyperpigmentation (darkening), particularly on knuckles and elbows.
  • Digestive issues, including nausea and occasional vomiting.
  • Increased anxiety and difficulty concentrating.
Medical History:
  • Autoimmune thyroiditis was diagnosed and treated with levothyroxine.
  • No history of major illnesses or surgeries.
  • Family history of autoimmune disorders.
Physical Examination:
  • Low blood pressure (hypotension).
  • Abdominal pain upon palpation (suggestive of adrenal insufficiency crisis).
  • Hyperpigmentation of skin and mucous membranes.
Laboratory Tests:
  • Baseline cortisol: low (suggestive of primary adrenal insufficiency).
  • ACTH (adrenocorticotropic hormone) stimulation test: abnormal response, confirming adrenal insufficiency.
  • Electrolytes: potassium slightly elevated, sodium slightly low.
  • Random blood sugar: low (hypoglycemia).
  • Autoimmune antibodies: positive for adrenal cortex antibodies, confirming Addison’s disease as the likely cause.

Diagnosis: Addison’s disease (primary adrenal insufficiency) with adrenal crisis presentation.

  • Emergency intravenous fluids and electrolytes to stabilize blood pressure and blood sugar.
  • Long-term replacement therapy with hydrocortisone (oral cortisol) and fludrocortisone (mineralocorticoid) to mimic natural hormone production.
  • Dietary adjustments to manage blood sugar and electrolytes.
  • Stress management techniques and psychological support to address anxiety and fatigue.
Recommended Tests:
  • Baseline cortisol and ACTH levels.
  • ACTH stimulation test to differentiate between primary and secondary adrenal insufficiency.
  • Electrolytes (sodium, potassium, chloride) and blood sugar monitoring.
  • Autoimmune antibodies to identify the underlying cause of adrenal insufficiency.
  • Additional tests, like an abdominal CT scan, may be recommended if an adrenal tumor is suspected.
  • Regular monitoring of cortisol, electrolytes, and blood sugar levels.
  • Dose adjustments of hormone replacement therapy based on individual needs and symptoms.
  • Ongoing education and support to help Sarah manage her condition and improve her quality of life.

Sarah’s case exemplifies the multifaceted nature of adrenaline’s paradox in Addison’s disease. The lack of adrenaline, coupled with impaired cortisol production, creates a cascade of symptoms mimicking both the fight-or-flight response (anxiety) and its antithesis (fatigue, low blood sugar). The case also highlights the importance of a comprehensive diagnostic approach, including specific hormonal and autoimmune tests, for accurate diagnosis and timely intervention. While medical management with hormone replacement therapy plays a crucial role, Sarah’s journey to recovery also benefits from stress management techniques and self-awareness, empowering her to navigate the challenges of living with a chronic condition.
