chrisincontrol11 - high potassium is called hyperkalemia. I was diagnosed with this condition some 6 years ago (I think, not sure of exact dates), there are various causes, google it for further information. It makes for scary reading, but your doctor has not admitted you to hospital, thats a good sign and hopefully this condition is temporary and can be managed on outpatient level. My symptoms were nausea, leg pain, leg cramps, fatigue.
Mine was due to blood pressure medication and CKD stage 3, I was advised to not to eat bananas, avocadoes, oranges, nuts and a whole host of other foods.
My bp medication was changed, kidneys remained stable, at that time I was still having problems with bg control.
Eventually the penny dropped, I realised that by reducing carbs in my diet I was able to lower bg levels, it went on from there, been lowcarbing for the past 4yrs. I have been able to stop all medication with agreement of HCPs, kidney function improved from stage 3 to stage 2, it has been stable at stage 2 for the past 3 years.
Potassium levels have returned to normal, I would not eat bananas and oranges, dried fruits, etc on low carb diet, avocados, nuts, hummous are low carb and high potassium, I can eat them.
Its a shame that its not possible to test potassium levels at home, I had to have fortnightly blood tests, in between I worried myself sick wondering what my levels are.
I hope you feel better soon.
