Discharge Instructions for Hyperkalemia

Choose a preferred language

You have been diagnosed with hyperkalemia. This means you have a high level of potassium in your blood. Potassium is important to the function of the nerve and muscle cells. This includes the cells of the heart. But a high level of potassium in the blood causes serious problems. These include abnormal heart rhythms and even a heart attack.


Diet changes

Eat less of these potassium-rich foods:

  • Bananas

  • Apricots, fresh or dried

  • Prunes, dates, and raisins

  • Nectarines

  • Kiwifruit

  • Oranges and orange juice

  • Grapefruit juice

  • Tomatoes, tomato sauce, and tomato juice

  • Spinach

  • Green, leafy vegetables, including salad greens, kale, broccoli, chard, and collards

  • "Lite" or reduced-sodium salt, or salt substitutes


Other home care

  • Tell your doctor about all prescription and over-the-counter medicines you take. Also tell them about herbal or dietary supplements you are taking. Certain medicines and supplements can increase potassium levels.

  • Take all medicines exactly as directed.

  • Have your potassium levels checked regularly.
