Having too much potassium in your blood can be dangerous. Potassium affects the way your heart’s muscles work. When you have too much potassium, your heart may beat irregularly, which in the worst cases, can cause heart attack.

If you think you are having a heart attack, call 911 for emergency help.

Some of the most common signs of heart attack are:

  • Feelings of pressure, pain, or squeezing in your chest or arms
  • Stomach pain or nausea
  • Shortness of breath
  • Breaking into a cold sweat
  • Sudden feelings of dizziness
