Clinical significance

A cation found almost exclusively inside cells, especially in bone tissue. Blood magnesium levels are only a moderately reliable indicator of overall magnesium reserves because they can be normal even in patients with serious deficiency. Excess magnesium causes central nervous system depression and neuromuscular irritability secondary to renal or thyroid insufficiency or an adverse drug reaction. Magnesium deficiency can be due to inadequate intake, losses via the intestine or the kidneys, or to drug-induced inhibition of tubular reabsorption especially aminoglycoside antibiotics and diuretics.
