Potassium is a mineral that occurs naturally 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 others may cause it to drop.
You may need to avoid or eat more foods high in potassium. Ask your health care team about what is right for you.
The charts below show foods that are high, moderately high and low in potassium.
