Primary hyperaldosteronism is found in up to 13% of patients with hypertension. This article describes a patient with hypokalemia, hypertension, and periodic paralysis that were caused by primary hyperaldosteronism. Plasma aldosterone concentration to plasma renin activity ratio is a common screening test, and adrenal vein sampling can be performed to determine which gland is overproducing aldosterone. Treatment with mineralocorticoid receptor antagonists or adrenalectomy gives similar reductions in BP.
