ACTH: Unmasking Secondary Adrenal Insufficiency

December 22, 2023by Dr. S. F. Czar0

Patient: Sarah, a 52-year-old registered nurse, known for her vibrant energy and dedication (ACTH).

Presenting Symptoms: For the past six months, Sarah has noticed a gradual decline in her health. She experiences chronic fatigue, waking up feeling unrested even after eight hours of sleep. Weight loss despite maintaining a healthy diet adds to her worries. Muscle weakness, particularly in her legs, makes climbing stairs a laborious task. Digestive issues like nausea and occasional vomiting further disrupt her daily routine.


Medical History:

Sarah has a history of chronic stress due to her demanding job and caring for her aging parents. Five years ago, she underwent pituitary surgery to remove a benign tumor.

Initial Diagnosis:

Based on Sarah’s symptoms and history, her doctor suspects secondary adrenal insufficiency.


  • Laboratory Tests: Low cortisol levels and elevated ACTH levels confirm the diagnosis.
  • Imaging Tests: An MRI reveals no residual pituitary tumor but shows signs of mild pituitary atrophy.


Secondary adrenal insufficiency due to pituitary dysfunction, likely a sequelae of her surgery.

Treatment Plan:

  • Corticosteroid Replacement Therapy: Sarah is prescribed oral hydrocortisone, mimicking the body’s natural cortisol rhythm.
  • Stress Management: Sarah is referred to a stress management therapist who teaches her mindfulness and relaxation techniques.
  • Lifestyle Modifications: She is encouraged to prioritize regular exercise, healthy sleep habits, and a balanced diet.

Within weeks of initiating treatment, Sarah experiences significant improvement. Her energy levels increase, fatigue subsides, and muscle weakness diminishes. Digestive issues ease, and her weight stabilizes. Sarah actively participates in stress management practices, finding the techniques helpful in navigating her daily challenges.


Sarah’s case exemplifies the intricate presentation of secondary adrenal insufficiency. Chronic stress, a risk factor, likely worsened the hormonal imbalance caused by her pituitary dysfunction. Early diagnosis and prompt treatment, combined with stress management and lifestyle modifications, were crucial in restoring Sarah’s health and well-being.

Key Takeaways:

  • Secondary adrenal insufficiency can present with diverse symptoms, often mimicking chronic stress.
  • A thorough medical history and appropriate investigations are necessary for accurate diagnosis.
  • Individualized treatment plans, including corticosteroid replacement, stress management, and lifestyle changes, are essential for optimal management.
  • Early diagnosis and proactive management can empower individuals with secondary adrenal insufficiency to lead fulfilling lives.
