Abstract

Hypomagnesemia is defined as serum [Mg2+] < 1.7 mg/dL. The prevalence of hypomagnesemia in outpatient and hospitalized patient population is 6–12 %. The incidence of hypomagnesemia is approximately 65 %. The causes of hypomagnesemia fall into four major categories: (1) decreased intake of Mg2+; (2) decreased intestinal absorption; (3) increased urinary losses; and (4) drugs. In addition to these causes, transcellular transport of Mg2+ into the cell is caused by infusion of glucose or epinephrine.
