Siadh serum osmolality and serum sodium
WebSerum sodium may be low when severe hyperglycemia (or exogenously administered mannitol or glycerol) increases osmolality and water moves out of cells into the ECF. Serum sodium concentration falls about 1.6 mEq/L (1.6 mmol/L) for every 100-mg/dL (5.55-mmol/L) rise in the serum glucose concentration above normal.
