Palpitations is the biggest issue. If left unchecked, you heart will most likely go into A-Fib(heart chambers are out of sync). If it’s bad enough, a heart attack will occur. On your blood test results the level is 3 to 5 roughly, in between is desired, my last one in May was 4.1. So 5 is high, 5 to 6 is higher but not good. Above 6 to 6.5 is in the danger zone, and you should be warned by your pcp it need attention immediately. 6.5 to 6.8 is in the critical zone, and you should be sent to the hospital for treatment. At 6.9. and 7, you might be taken to the morgue if your heart hasn’t gone back into normal rhythm. I was at 6.7. & 6.8, and a number of my doctors kept calling me to get me to go to the ER immediately

If you must take Spiro, like I do, you’ll learn what things are dangerous. A simple misjudgment on my part shot my potassium up to the 6.8 level. That’s when I learned a valuable lesson, Don’t just thing it’s not to high a potassium food, most food labels say per serving. My mistake was the amount was high but there were 3 1/2 serving in the whole can of soup I consumed. So instead of only 400 it turned into 1400 times two days in a row made it 2800, ouch.

Off hand some other symptoms may be abdominal pain, chest pain, nausea and vomiting and a few more. So your doctor or technician should give you a daily amount you’re allowed to eat. That includes anything you put in your mouth that has potassium in to and that’s almost everything. Good luck
