Hyponatremia is the most frequent hydroelectrolytic disorder observed in hospitalized patients and it is important to note that it has been associated with morbidity and mortality in this patients. This entity represents a pathophysiological process related to an alteration in water homeostasis, in which patients present symptoms mostly neurological, that correlate with the sodium level and the time of onset of the disorder. A search of the PubMed and Lilacs databases of monographies, review articles and originals articles was performed with the objective to review clinical, diagnostic and management aspects of this entity. For diagnosis, the clinical laboratory studies are requested depending on the clinical context, acting early and allowing correction of the disorder according to the respective scenario. Hyponatremia is a frequent medical problem that requires a practical and simple approach favoring clinical decisions in a timely manner. MÉD.UIS. 2020;33(2):85-93.
