Electrolyte and renal changes in severe potassium depletion.

This report describes electrolyte changes and some clinical aspects of the renal disease associated with the loss of potassium through the gastrointestinal tract in 2 patients with diarrhea. In one of them, the diarrhea resulted from non-tropical sprue, in the other, from non-beta islet-cell adenoma of pancreas. In both patients, some observations were repeated after potassium repletion.
