Normal sodium range from 135 to 145. Low sodium (hyponatremia) is less than 135. Some may have no symptoms at slight decrease in sodium level especially if the level dropped slowly. Rapid decrease or large drop in levels can cause confusion, seizures, coma and even death. Labs should always be rechecked to exclude false abnormal level.
