The normal adult value for sodium is 136-145 mEq/L.
Changes in your body's sodium levels directly affect your body's blood volume (how much water your blood contains). The most common form of sodium imbalance is a blood sodium level that is too high. Excessive blood sodium levels means that your body lacks enough water to cope with the amount of sodium it contains.
