If you are on hemodialysis and have treatments three times per week, you will likely need to strictly limit potassium, sodium, phosphorus and fluids. This is because when your blood is being cleaned only three times per week, there is more time between treatments for waste and fluid to build up in your blood. You may also need to limit how much protein you take in. If you do hemodialysis at home, and do your treatments every day, you may be able to be less strict with your diet. Talk to your dietitian about making a diet plan that is right for you.
