The kidneys regulate the concentration of potassium in the blood and eliminate it when levels are too high. When kidney function is impaired, potassium may build up in the blood and cause heart problems.
Therefore, CKD patients may need to limit dietary potassium intake. Recommended potassium intake varies depending on the severity of CKD and the individuals' overall health picture. Blood potassium levels should be checked regularly.
