When you have kidney disease your electrolytes and minerals in the body can be unbalanced. One of the electrolytes controlled by the kidney is potassium. Potassium is very critical in cardiac function. It can also affect your muscles. It can cause muscle weakness. Potassium levels need to be very carefully monitored in chronic kidney disease. Your nephrologist can help you monitor your potassium levels as well as other electrolyte levels.
