Impaired renal phosphate excretion *Decreased kidney function *Low parathyroid hormone *Developmental *Autoimmune *After neck surgery or radiation *Activating mutations of the calcium-sensing receptor *Parathyroid suppression *Parathyroid-independent hypercalcemia *Vitamin D or vitamin A intoxication *Sarcoidosis, other granulomatous diseases *Immobilization, osteolytic metastases *Milk-alkali syndrome *Severe hypermagnesemia or hypomagnesemia *Pseudohypoparathyroidism *Acromegaly *Tumoral calcinosis *Heparin therapy Massive extracellular fluid phosphate loads *Rapid administration of exogenous phosphate (intravenous, oral, rectal) *Extensive cellular injury or necrosis *Crush injuries *Rhabdomyolysis *Hyperthermia *Fulminant hepatitis *Cytotoxic therapy *Severe hemolytic anemia *Transcellular phosphate shifts *Metabolic acidosis *Respiratory acidosis Hypoparathyroidism: In this situation, there are low levels of parathyroid hormone (PTH). PTH normally inhibits reabsorption of phosphate by the kidney. Therefore, without enough PTH there is more reabsorption of the phosphate leading to a high phosphate level in the blood. Chronic kidney failure: When the kidneys are not working well, there will be increased phosphate retention. Drugs:<unk>  can also be caused by taking oral sodium phosphate solutions prescribed for bowel preparation for colonoscopy in children.
