Overview of Electrolytes
Electrolytes are minerals that circulate in your blood. These minerals are also in your stomach juices, in your stool (poop), in your urine, and inside your body's tissues. Salt (sodium) is one example of an electrolyte. Others include potassium, calcium, and magnesium.
Electrolytes help in many different body functions:
Your kidneys keep the right balance of electrolytes in your blood. Having too much or too little of an electrolyte can cause health problems.
Your doctor will try to restore your balance of electrolytes. If you have too little of an electrolyte, you'll usually be given more of that electrolyte by mouth or in your veins (IV). If you have too much of an electrolyte, you may get fluids by IV or a medicine to help remove it from your body. Some serious electrolyte problems can require kidney dialysis.
