Method: Patients >= 65 years and with severe hyponatremia (serum sodium levels <= 125 mEq/L) were included in the analyses. Results: Fifty-five patients were hypovolemic, 22 were normovolemic, and 23 were hypervolemic. 65.5% (n = 36), 59.1% (n = 13) and 60.9% (n = 14) of the groups were females (p > 0.05), and regarding comorbidities, 27.3%, 9.1%, and 4.3% of the groups were diagnosed with a malignancy, respectively (p = 0.031). Conclusions: Early diagnosis and treatment in the emergency department are critical considering the severity and prognosis of hyponatremia.eninfo:eu-repo/semantics/openAccessEmergency MedicineGeriatricsHyponatremiaArticle251132110.31086/tjgeri.2022.258Q4WOS:0007764950000022-s2.0-851283443651174362Q4
