Figure 1. Hyponatremia management algorithm[38,44-48]. The correct management of hyponatremia and its treatment require the detection of its cause. Plasmatic osmolarity and ECV evaluation are necessary to recognize the origin of hyponatremia. Symptomatic hyponatremia should be treated with hypertonic saline solution. Tolvaptan should be considered in hyponatremia due to SIAD. ECV: extracellular volume; SIAD: syndrome of inappropriate antidiuresis
