Hypermagnesemia


WHAT WENT WRONG?


Hypermagnesemia is a greater-than-normal amount of magnesium in the blood.
Patients with poor renal function or long-term abuse of magnesium-containing
compounds have difficulty excreting magnesium. The excess of magnesium in the
blood causes the cell membranes to become less excitable than normal, requiring
a greater stimuli than would normally be needed to cause a required effect. As the
magnesium level continues to rise, the cell membrane becomes more resistant to
its natural stimuli.
