Low sodium level With low sodium level (hyponatremia), the imbalance of water to salt is caused by one of three conditions: 1  Euvolemic hyponatremia -- total body water increases, but the body's sodium content stays the same.  Hypervolemic hyponatremia -- both sodium and water content in the body increase, but the water gain is greater.

Low sodium level Low sodium level. Low sodium level is a condition in which the amount of sodium (salt) in the blood is lower than normal. The medical name of this condition is hyponatremia. Sodium is found mostly in the body fluids outside the cells. It is very important for maintaining blood pressure. Sodium is also needed for nerves, muscles, and other body tissues to work properly. When the amount of sodium in fluids outside cells drops below normal, water moves into the cells to balance the levels.

- Too Little Salt (Low Sodium Levels) As stated above, not enough sodium in your body can also cause health problems. That's because a lack of sodium causes your body's blood volume to decrease. This, in turn, will lead to a corresponding decrease in your blood pressure level, a condition known as hypotension.

- Causes. Hyponatremia occurs when the body contains too little sodium for the amount of fluid it contains (see Overview of Sodium). The body may have too much, too little, or about a normal amount of fluid. In all cases, however, sodium is diluted.For example, people with severe vomiting or diarrhea lose sodium.n hyponatremia, the level of sodium in blood is too low. A low sodium level has many causes, including consumption of too many fluids, kidney failure, heart failure, cirrhosis, and use of diuretics.

- How to Identify Symptoms of Sodium Imbalance. Sodium is a mineral that is essential to optimal body functioning. It helps the body maintain normal fluid balances, nerve impulse transmission and a proper acid-base balance within tissues. Lack of proper sodium balance may cause high blood pressure, cramps, mental sluggishness and loss of appetite.
