Answer

Hypomagnesemia can result from decreased intake, redistribution of magnesium from the extracellular to the intracellular space, or increased renal or gastrointestinal loss. An additional element of variability is the difference between total versus ionized magnesium concentration, the latter being influenced by plasma protein concentration and the acid-base status [74] . In some cases, more than one of these may be present.
