Electrolytes are minerals found in blood and other bodily fluids. They are electrically charged and, as such, essential to keeping the heart, nerves and muscles functioning properly. With this in mind, it’s important to maintain a precise and constant balance of electrolytes to stay healthy. The kidneys play an important role in ensuring that fluid and electrolyte levels remain in range despite any changes the body may undergo. Having an excess — or an insufficiency — of electrolytes in the body can be dangerous and, in some cases, fatal.
