Addison's Disease: A Diagnosis Easy to Overlook

Area of Science:

• Endocrinology
• Internal Medicine

Background:

• Addison's disease is a rare, life-threatening endocrine disorder often diagnosed late due to nonspecific symptoms.
• Fatigue and electrolyte imbalances like hyponatremia are common initial presentations.

Observation:

• A 43-year-old male presented with malaise, fatigue, anorexia, weight loss, severe hyperpigmentation, and hypotension.
• Laboratory findings included hypoosmolar hyponatremia, normal-range potassium, elevated ACTH and renin, and low cortisol and aldosterone.

Findings:

• The patient was diagnosed with Addison's disease based on clinical presentation and hormonal profile.
• Treatment led to symptom resolution, normalized electrolytes, and improved hyperpigmentation.

Implications:

• Prompt diagnosis and treatment of Addison's disease allow patients to resume normal activities.
• Lifelong surveillance is essential for managing this chronic condition.
