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.
If the concentration of sodium is too high in the bloodstream, water will leak from cells into the blood stream to try to dilute and lower the sodium concentration. Conversely, if sodium levels in the bloodstream are too low, water will leave the blood and enter cells, causing them to swell. Hyponatremia is the term used to describe low sodium levels in the bloodstream (hypo=low + natr=sodium + emia=blood).
