Signs And Symptoms Of Hyponatremia

Hyponatremia is characterized by anomalous low sodium serum levels. Sodium is very important in balancing and supporting the blood pressure level. The nerves, muscles, and other body tissues rely on sodium to function properly.

When the body tries to compromise for the lack of sodium, in fluids outside the cells. Water will move into the cells to help accommodate and balance the levels. This in turn causes the cells to become engorged in excess water. Brain cells are very sensitive to this reaction and the individual will begin to experience mild to severe symptoms.
