A Quick Reference on Hyponatremia

Julien Guillaumin et al. Vet Clin North Am Small Anim Pract. 2017 Mar.

Abstract

The article focuses on causes of hyponatremia, including hypovolemia, diabetes mellitus and others. Hypovolemia is a major cause of hyponatremia in veterinary medicine. Hypovolemia causes a decrease in effective circulating volume, triggering antidiuretic hormone (ADH) secretion and free water retention, and develops after gastrointestinal losses, renal losses, hemorrhagic shock, hypoadrenocorticism, and other causes of hypovolemia. The article reviews the clinical approach to diagnosing the cause of hyponatremia in critically ill patients, including recognition of the syndrome of inappropriate ADH secretion (SIADH).

Keywords: Diabetes mellitus; Electrolytes; Hyponatremia; SIADH; Sodium.
