Greetings ! I am a healthy 55 yr old woman being scheduled for an L-5 , S-1 discectomy in 7 days however , my blood potassium level is slightly elevated & my Dr. is concerned . Also , oddly , my heart is now galloping about & I am scheduled to see a cardiologist tomorrow . I take vitamins ... how did this high potassium level happen & how can I remedy this ? I am rather concerned & VERY surprised at this strange turn of events ! Thank you so much - Carol
