Sodium & Potassium
The kidneys regulate fluid absorption and excretion and maintain a narrow range of electrolyte fluctuation. Normally, sodium and potassium are filtered and excreted in the urine and feces according to the body’s needs. Too much or too little sodium or potassium, caused by poor diet, dehydration, medication, and disease, results in an imbalance. Too much sodium is called hyperNAtremia; too little is called hypoNAtremia. Too much potassium is called hyperKalemia; too little is called hypoKalemia.
