Self medicating with potassium may be dicey for some people.

Renal tubular acidosis can be present and potassium is involved with this. One type there can be too much postassium (conserved by the kidney) and another type can be potassium wasting. So having medical testing is important if you supplement potassium. This is one reason why potassium supplements are limited by the FDA to 99mg per tablet.

Chronic diarrhea also wastes potassium as the body stores potassium for short periods of time in the large colon...and then resorbs it to help balance serum fluctuations from food intake. If the transit time in the colon is accelerated, this potassium is lost. And if a blood test results in lysed red blood cells (which is common) the test itself may show a false positive elevation. This is very common and you can Google it, further.
