2. Chronic Kidney Disease
If you test very high for potassium, one possibility may not be a problem with your diet but with kidney function. The kidneys cleanse the body of excess materials such as toxins and electrolytes, such as potassium. If the kidneys no longer function properly, the waste builds up in the body. There may be problems with excretion and difficulties with urination. Unlike acute kidney failure, which has a rapid onset, chronic kidney disease can happen gradually, and the loss of function may not be noticed until it becomes quite pronounced.
If chronic kidney disease is not treated or becomes worse, it may not be possible to excrete waste properly without dialysis. In some cases, a kidney transplant may be needed. Those with chronic kidney disease may be given a special diet that will be difficult for the kidneys to excrete. The patient may be encouraged to cut down on potassium and other electrolytes.
