If you learn that you have hyperkalemia, your doctor might suggest that you change your diet to take in less potassium. To do this, you may need to stay away from foods that are very high in potassium, such as baked potatoes and baked winter squash. Remember that drinks have potassium in them, too! You should also avoid salt substitutes because they are usually high in potassium.
Because so many healthy foods have potassium in them, and because you do need some potassium every day, it is important to know which foods are good choices. It is also important to pay attention to serving sizes. Use measuring cups and measuring spoons to make sure you know how many servings you are eating or drinking. Remember that if you eat two servings, you are eating twice as much potassium!
Talk to your doctor or dietitian about how much potassium you should have and how you can control how much you take in. Your dietitian can recommend foods that are lower in potassium that you can eat instead of foods that are high in potassium.
Your doctor might also tell you to take a medicine called a potassium binder. This type of medicine works by sticking to the potassium in your body and preventing some of it from being taken into your bloodstream. This helps to keep potassium from building up in your blood. The medicine is a powder, which you will take by mixing it with a little bit of water and drinking it. Talk to your doctor to find out if a potassium binder is an option for you.
