POTASSIUM

Potassium is a mineral. Healthy kidneys maintain a normal balance by eliminating any excess potassium in the urine. Diseased kidneys are unable to get rid of the potassium adequately. Consequently, the amount of potassium in the blood may increase to dangerously elevated levels. This may cause an irregular heartbeat and occur without any warning. High levels of potassium can even cause the heart to stop.

The dialysis patient needs to maintain a level of potassium in the blood, between 3.5 and 5.5 milliequivalents per liter. It is easier for the patient who still urinates to control potassium. The following is a list of high potassium foods which should either be avoided or carefully included into your diet by working with the renal dietician. Remember these are average values. The size of the portion is the secret of the diet, as almost all foods have
potassium. Please pay particular attention to your monthly blood levels of potassium. Your diet is usually limited to around 2000 milligrams per day.
