Electrolyte disorders result in an imbalance of minerals in the body. For the body to function properly, certain minerals need to be maintained in an even balance. Otherwise, vital body systems, such as the muscles and brain, can be negatively affected. Electrolytes refer to minerals that include calcium, chloride, magnesium, phosphate, potassium, and sodium. They are present in your blood, body fluids, and urine. They are ingested with food, drink, and medicines and supplements.
