Elderly patients are at an increased risk of developing both hypophosphatemia and
hyperphosphatemia. Renal insufficiency predisposes elderly patients to elevated serum
concentrations of phosphate. On the other hand, poor dietary intake and loss of phosphorus
in the urine can lead to deficiency states. It is well documented that hyperphosphatemia
is correlated with an increase in morbidity and mortality as a result of vascular
calcification. This article reviews the etiology, pathophysiology, symptoms, and treatment
of hypophosphatemia and hyperphosphatemia.
