Hypernatremia, Signs & Symptoms of

🖇️ High levels of sodium can lead to a condition called hypernatremia, where the serum sodium concentration > 145 mEq/L (> 145 mmol/L). ⁠

🖇️ Sodium is a dominant cation in extracellular fluid and necessary for the maintenance of intravascular volume. When there is a large increase in sodium in the serum, the signs and symptoms often relate to fluids as you can see with today’s mnemonic.⁠

🖇️ The human body maintains sodium and water homeostasis by concentrating the urine secondary to the action of antidiuretic hormone (ADH) and increased fluid intake by a powerful thirst response.⁠
