Etiologies of hypophosphatemia

	Acute hypophosphatemia	Chronic hypophosphatemia
Decreased phosphate intake		Inadequate parenteral nutrition Nutritional defects
Decreased intestinal absorption		Vitamin D deficiency Vitamin D-dependent rickets Chronic anti-acid therapy Intestinal malabsorption Chronic liver disease Alcoholism
Increased renal wasting of primary renal disease	After renal transplantation (first weeks) Acute volume expansion	De De Toni Debre Fanconi syndrome Dent disease Toxic (ifosfamide, platin salts, diuretics, glucocorticoids, retroviral therapies in HIV patients, acetazolamide)
Hyperparathyroidism		Primary and secondary hyperparathyroidisms
Increased FGF23 serum levels		Hypophosphatemic rickets Tumor-induced osteomalacia Fibrous dysplasia Mac Cune Albright syndrome Toxic (saccharated ferric oxide)
Redistribution of phosphate between the different compartments	After bone marrow transplantation Acute leukemia and lymphoma Correction of diabetic ketoacidosis Refeeding Acute respiratory alkalosis Hungry bone syndrome	Treatment with erythropoiesis-stimulating agents in patients with cirrhosis
Miscellaneous	Severe sepsis Extensive burns Inadequate dialysis Acute paracetamol overdose Salicylate poisoning Hypothermia
