Hyponatremia refers to a lower-than-normal level of sodium in the blood. Sodium is essential for many body functions including the maintenance of fluid balance, regulation of blood pressure, and normal function of the nervous system.
It occurs when water and sodium are out of balance. In other words, thereâs either too much water or not enough sodium in your blood. Normally, your sodium level should be between 135 and 145 milliequivalents per liter (mEq/L). Hyponatremia occurs when your sodium level goes below 135 mEq/L.
