How is your health?
Do you take any medication?
Do you have any kidney problems?
What is yout diet like?
Thank you for the information.
Normally if an unexpectedly high potassium is obtained then the test needs to be repeated to rule out an error in the previous test. Do check that a new sample was taken from a different site and repeat the potassium check.
You do not mention any diuretics which are the most common cause of raised potassium, nor any NSAIDs such as ibuprofen. Diarrhea and vomiting can also cause irregular levels.
If none of these reversible conditions occurred then I would suggest you use the medication because a raised potassium is very serious for the functioning of the heart.
When people have kidney problems then we recommend low potassium diet such as avoiding bananas, boiling vegetables before consumption and avoiding chocolate.
I think these factors could certainly contribute to your problem, this should be brought to the attention of your doctor however the short term need is to bring it back to normal as soon as possible so do follow your doctor's instructions. Improving your fluid intake within moderation should help.
