Hyperaldosteronism: Aldosterone causes loss of k+ in exchange for na+ in the nephron. The volume of water in the urine will follow the na+ back into the blood leading to an increase in blood pressure. Secondary hyperaldosteronism is the pathologically increased secretion of this & renin which could be from renal artery stenosis or other rare causes. See your physician to get it figured out.
