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.
The body needs sodium to help keep fluids in balance. After you consume sodium, the body processes it through the kidneys and sends excess out of the body in sweat and urine. Low sodium levels can occur when there is not enough sodium in the blood compared to the amount of fluid, so sodium dilution occurs. Normal blood levels for sodium range between 135 and 145 milliequivalents per liter, according to the University of Maryland Medical Center.
