<unk>  is caused by the following three mechanisms: * Inadequate intake (often unmasked in refeeding after long-term low phosphate intake) * Increased excretion (e.g. in hyperparathyroidism,<unk>  rickets) * Shift of phosphorus from the extracellular to the intracellular space. This can be seen in treatment of diabetic ketoacidosis, refeeding, short-term increases in cellular demand (e.g. hungry bone syndrome) and acute respiratory alkalosis.
