What causes hyponatremia (low blood sodium)? A low sodium level in the blood may result from excess water or fluid in the body, diluting the normal amount of sodium so that the concentration appears low.
If blood sodium levels are low due to insufficient intake, then urine concentrations will also be low. 1  Decreased urinary sodium levels may indicate dehydration, congestive heart failure, liver disease, or nephrotic syndrome. 2  Increased urinary sodium levels may indicate diuretic use or Addison disease.
