Corticosteroids · Pharmacology

Sudden withdrawal of long-term corticosteroid therapy can lead to life-threatening acute adrenal insufficiency primarily because:

  1. The kidneys progressively develop resistance to aldosterone and can no longer adequately retain sodium
  2. Exogenous steroids cause atrophy of the adrenal cortex via HPA axis suppression
  3. Steroids are required for the absorption of dietary sodium
  4. The liver stops producing glucose without exogenous steroids
Show answer and explanation

Correct answer: Exogenous steroids cause atrophy of the adrenal cortex via HPA axis suppression

Chronic corticosteroid use suppresses the secretion of CRH and ACTH through negative feedback. This leads to atrophy of the adrenal glands, which cannot immediately produce endogenous cortisol if the medication is stopped abruptly.
