Sodium plays many important roles in the body. It maintains fluid balance and is a main nutrient used in nerve impulse transmission and muscle contraction. The normal range for blood sodium is between 135 and 145 mEq/L (3.10 mg/ml to 3.34 mg/ml). Higher levels of sodium are normally associated with hypertension. A sodium level of 150 mEq/L (3.45 mg/ml) or more is known as hypernatremia, a condition that is commonly caused by dehydration or eating too much salt. However it can also be caused by other conditions such as diabetes or hormonal imbalances.
Normal Sodium Levels. Normal sodium levels are needed for maintaining good health. The normal level of sodium of every person significantly differs and depends upon the age, sex and health condition of the individual. Sodium levels that are far from the normal range can be fatal, so knowing the level of sodium in the body is extremely important.
