What happens if you do not have enough sodium in your diet?

As long as you eat a well-balanced diet, you have little risk of your body not getting enough sodium. Most people in developed countries consume more than enough sodium from foods and beverages they consume each day. Hyponatremia, a level of sodium depletion that is quite serious and can lead to disorientation, confusion and seizures, is very rare and occurs primarily in endurance athletes, such as marathon runners, who lose both salt and fluids through sweat, but replace only fluids.
