What causes fluctuation in potassium levels?
My kidney function is good and no evidence of kidney disease.
Please help as this is making my anxiety go through the roof.
they may fluctuate but not much
first of all 5.9 is too high. This is not normal. Make sure the specimen was not hemolyzed (the lab should have noted it, although this is not always the case). The causes of high potassium are not easy to approach without a detailed medical history, drug review and testing. You'd better check the hemolysis suspicion by talking to the lab or checking the report. Hemolysis makes potassium levels to rise. If there's no hemolysis I would suggest repeating the test to see if 5.9 is persisting. If it does then further investigation would be required.
At these levels there is no immediate danger, so don't worry too much about it.
