Importance of Electrolyte Balance in the Body

Distance runners need to watch their electrolyte balance

The human body is made up of over 60 percent water. That water contains a mixture of minerals, including sodium, calcium and potassium. Those minerals collectively are known as electrolytes.

Loss

Electrolytes and water are lost through kidney functions, sweat and the moisture in breath. They need to be replaced through food and drink.

Thirst

Thirst is the first sign that something needs to be done. Water is replaced through drinking, which helps the overall electrolyte balance.

Hyponatremia

A low sodium level in known as hyponatremia. This can be a problem with endurance athletes and distance runners. Symptoms include confusion, weakness and drowsiness. The level can be restored gradually through intravenous fluids.

Hyperkalemia

Hyperkalemia is a high potassium level. It is usually caused by kidney failure or medications. It can cause heart problems, and prescription drugs are used to treat it.

Hypocalcemia

A low calcium level is called hypocalcemia. Symptoms are weakness and numbness. It's treated by taking calcium orally.

In Conclusion

Electrolytes are an important part of the makeup of the human body. Too much of too little of the minerals that make up the electrolytes can cause serious problems. A doctor can give more information.
