Characteristic feature of primary aldosteronism is -
hyper secretion of aldosterone increases renal distal tubular exchange of intra tubular sodium for secreted potassium and hydrogen ions, with progressive depletion of body potassium resulting in hypokalemia ( Harrison 17 pg 2260)
Low serum sodium
High plasma renin
Low serum potassium
High serum creatinine
