How to Measure Sodium Levels

Having high levels of sodium in your body on a consistent basis can cause a myriad of health problems. If the sodium levels are not decreased, vital organs like your kidneys and heart can be permanently damaged. Doctors who suspect that a patient is overdoing it on the table salt will often request blood or urine tests. For patients who tend to ignore a doctor's advice, physically seeing proof that sodium levels are too high may be the impetus necessary to start making appropriate lifestyle changes.
