• Decreased intake/absorption: Starvation, Alcoholism, Malabsorption, Phosphate binder use
• Redistribution/ Shift into cells
- Acute- without depletion: Respiratory alkalosis, Insulin, Catecholamines
- Acute- with depletion: Refeeding (starvation, alcoholism, malabsorption), Hungry bone syndrome
• Renal losses: FGF23, PTH, Fanconi, Post transplant, Diabetes, Alcoholism
