(See Pathogenesis of metabolic alkalosis and Clinical manifestations and evaluation of metabolic alkalosis and Treatment of metabolic alkalosis.) INTRACELLULAR SHIFT OF HYDROGEN. Metabolic alkalosis can be generated by a shift of hydrogen ions into the cells. This most often occurs in patients with potassium deficits and hypokalemia. This may be an important pathophysiologic mechanism in patients with metabolic alkalosis due to vomiting or nasogastric suction [7].
