Prevalence of the degree of hyponatremia in patients with liver cirrhosis.

Hyponatremia is a hydroelectrolyte alteration defined as a serum sodium concentration lower than 135 mEq/L, being the most frequent electrolyte imbalance in clinical practice in patients with cirrhosis. Objective: To estimate the prevalence of hyponatremia degrees in patients with liver cirrhosis admitted to the Gastroenterology area of the Public Hospital in the period from January 2021 to June 2022. Methodology: Observational, retrospective, analytical and descriptive study; a sample of 111 patients whose information was obtained from medical records was analyzed. Results: The predominance of female sex was identified (50.5%), as well as age between 51 and 70 years (64.9%) and 72.1% had a hospital stay of 1 to 15 days. Mild hyponatremia had a prevalence of 23.7%, moderate hyponatremia a rate of 10.1% and severe hyponatremia a rate of 1.3%. Regarding comorbidities, cancer was the only one that was related to the degrees of hyponatremia. On the other hand, ADH was the only complication. We conclude that the prevalence of hyponatremia in these patients was 35.1%.
