I am not sure I see the problem. A normal potassium is 3.5 to 5.5 mEq per liter. A level of 4.7 is well within the normal range and should not cause concern. Dialysis is performed for kidney failure, which may include an elevated potassium, but is not performed for an elevated potassium alone. While a low potassium diet may help to lower the potassium levels, I am not sure this is indicated from the information that you present. There are medications that can be administer in order to lower the serum potassium, but again, I do not see this as necessary based on the information that you present. I suggest consultation with a nephrologist about this concern.
