Magnesium also controls blood sugar levels and helps support the body's defense (immune) system.
High magnesium levels may be seen in persons who have:
* Addison's disease
* Chronic renal failure
* Diabetic acidosis
Low magnesium levels may be seen in persons who have:
* Chronic diarrhea
* Delirium tremens
* Hepatic (liver) cirrhosis
* Too much insulin
