Overview
Differentiating Conn's Syndrome From Other Diseases
Conn's syndrome should be differentiated from other diseases causing hypertension and hypokalemia for example:[1][2][3]
- Renal artery stenosis
- Cushing's syndrome
- Congenital adrenal hyperplasia (CAH)
- 17 alpha hydroxylase deficiency
- 11 beta hydroxylase deficiency
- Liddle's syndrome
- Diuretic use
- Licorice ingestion
- Renin-secreting tumors
