Primary hyperaldosteronism
Increased aldosterone
Renin suppressed
Hypokalaemia
Hypomagnesaemia
Normal/high sodium
Alkalosis
Causes:
Conn’s syndrome (adrenal adenoma)
- Causes over 50%
Adrenal hyperplasia
Adrenal carcinoma (rare)
Isolated glucocorticoid deficiency (cortisol)
- Therefore, ACTH increases and over produces aldosterone
