The average sodium concentration at admission is 121.38 ± 9.07; 40% of patients have blood sodium concentration < 120 mmol/L, patients with sodium concentration between 120-129 mmol/L and ≥ 130 mmol /L account for 36% and 24% respectively. The proportion of asymptomatic hyponatremia patients is 46%, mainly in the mild hyponatremia group; The most common symptom is headache with 46%, often occurring in acute, moderate to severe hyponatremia.
