Why you need to control potassium

  • Potassium is a mineral that naturally occurs in your body. Potassium helps maintain the correct electrical environment for your heart.

    It is important to have the right amount of potassium in your body. If you have too much or too little, it can affect your heart rhythm. Some medicines may increase the amount of potassium in your body while other medicines may cause your potassium level to drop.

    Depending on your situation, you may need to avoid or eat more foods high in potassium. Ask your health care team about which course is best for you.

    The following chart shows you which foods are high and moderately high in potassium:
