Prevalence of hyponatremia in hospitalized patients from multiple studies came to be about 2.5%-30%.SIADH was the most common clinical setting in hospitalized patients with hyponatremia. The incidence and prevalence of SIADH in particular is less thoroughly studied in the literature.

Overview

Syndrome of inappropriate antidiuretic hormone (SIADH) can occur at any age. Its incidence depends upon various possible etiologies. Prevalence of SIADH was estimated to be 2500-3000 cases per 100,000 individuals. The incidence and prevalence of SIADH in particular is less thoroughly studied in the literature. Hospitalized patients with plasma sodium concentration <125 mmol/l show an overall mortality of 28000 per 100,000 patients. The incidence of SIADH increases with age. The prevalence and incidence of SIADH does not vary by gender. There is no racial predilection to SIADH.
