Modified Hyponatremia Algorithm
Hypertonic Hyponatremia: Hyperglycemia, Mannitol, Urologic irrigants
Hypotonic Hyponatremia: 
 • ADH ON (UOsm > 100):
    - RAAS ON (UNa < 30): Hypovolemia, Heart failure, Cirrhosis, Nephrotic syndrome
    - RAAS OFF (UNa > 30): SIADH, Medications (diuretics), Hypothyroidism, Adrenal insufficiency, Reset osmostat, Cerebral salt wasting
 • ADH OFF (UOsm < 100): Primary polydipsia, Low solute intake, Beer potomania
Isotonic Hyponatremia: Hyperlipidemia, Paraproteinemia, IVIG
