Hyponatremia and hypernatremia: disorders of water balance.
Total body water and tonicity is tightly regulated by renal action of antidiuretic hormone (ADH), reninangiotensin-aldosterone system, norepinephrine and by the thirst mechanism. Abnormalities in water balance are manifested as sodium disturbances--hyponatremia and hypernatremia. Hyponatremia ([Na+ < 136 meq/ l]) is a common abnormality in hospitalized patients and is associated with increased ...

متن کاملExercise-Associated Hyponatremia, Hypernatremia, and Hydration Status in Multistage Ultramarathons.
OBJECTIVE Dysnatremia and altered hydration status are potentially serious conditions that have not been well studied in multistage ultramarathons. The purpose of this study was to assess the incidence and prevalence of exercise-associated hyponatremia (EAH) (Na+ <135 mmol·L-1) and hypernatremia (Na+ >145 mmol·L-1) and hydration status during a multistage ultramarathon. METHODS This study inv...
متن کاملDiagnosis and management of sodium disorders: hyponatremia and hypernatremia.
Hyponatremia and hypernatremia are common findings in the inpatient and outpatient settings. Sodium disorders are associated with an increased risk of morbidity and mortality. Plasma osmolality plays a critical role in the pathophysiology and treatment of sodium disorders. Hyponatremia and hypernatremia are classified based on volume status (hypovolemia, euvolemia, and hypervolemia). Sodium dis...
