Your Care Instructions

Potassium is a mineral. It helps keep the right mix of fluids in your body. It also helps your nerves and muscles work as they should.

Most people get the potassium they need from the foods they eat. But if you have certain health problems, such as kidney disease, you may need to be careful about how much potassium you get. This is because too much potassium can be harmful.

You can control how much potassium you get if you eat foods that don't have much of it and you don't eat foods that have lots of it.

Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse call line if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.

How can you care for yourself at home?

  • Potassium is in many foods, including in vegetables, fruits, and milk products. Foods high in potassium include bananas, cantaloupe, and tomatoes. They also include foods like broccoli, milk, and potatoes.
  • Low-potassium foods include blueberries, raspberries, and cucumbers. They also include white or brown rice, spaghetti, and macaroni.
  • Do not use a salt substitute or "lite" salt unless you talk to your doctor first. These often are very high in potassium.
  • Be sure to tell your doctor about any medicines or natural health products you are taking. Some medicines can increase the potassium in your body.
