High potassium: no symptoms, but it can affect your heartbeat

High potassium usually has no symptoms — by the time you feel it, it is often very high. 5 things every kidney patient should know.

  1. 1Potassium leaves the body through the kidneys. As kidney function falls it builds up; very high levels disturb heart rhythm, can be fatal, and often cause no symptoms.
  2. 2Common high-potassium sources: banana, kiwi, orange juice, potato, tomato, dried fruit, nuts, chocolate, concentrated juices.
  3. 3"Salt substitutes" and "low-sodium" soy sauce usually replace sodium with potassium chloride — a hidden high-potassium source for kidney patients.
  4. 4Cutting vegetables and root crops small, soaking and boiling in plenty of water, then discarding the water removes part of the potassium; soups, stews and hot-pot broth keep it in the liquid.
  5. 5There is no one-size-fits-all potassium limit — guidelines say adjust to your blood level. Some kidney-protective medicines raise potassium; do not stop them yourself, ask your doctor to adjust.

If "K" is high on your report, ask your doctor first: is it diet, medication or constipation? Don't guess, and don't stop medicines on your own.

0–5Lab report: K 5.8 in redThis K on your report is high — and you may feel nothing at all.
5–15ECG waveform peakingPotassium leaves through the kidneys. When they weaken it builds up, and too much disturbs heart rhythm — fatal in severe cases, and usually silent.
15–26Line-up of high-potassium foodsCommon sources: banana, kiwi, orange juice, potato, tomato, dried fruit, nuts, chocolate.
26–35Zoom on label: potassium chlorideOne many people miss: salt substitutes and low-sodium soy sauce swap sodium for potassium chloride — high potassium for kidney patients.
35–46Chop → soak → boil → pour water awayChop vegetables small, soak, boil in plenty of water and discard it — that removes part of the potassium. Soups and hot-pot broth do the opposite: they keep it.
46–54Pill bag + "do not stop on your own"There is no single potassium limit — it depends on your blood test. Some kidney-protective drugs raise potassium; don't stop them yourself, let your doctor adjust.
54–60Site logo + URL + QRWant the potassium in any food? Beyond CKD has a 346-food lookup table and a diet calculator.
