I m a 76-yr-old female with diabetes, high blood pressure, both contained medically. Under a doctor s orders about a year ago, I was prescribed potassium because my level of potassium was low enough to necessitate immediate hospitalization with blood tranfusions. It hasn t been checked since then other than my annual blood lab draw in June of this year. At that time, my level was 2.6 (L). About 10 days ago, I began to experience the same fatigue, trembling and exhaustion. Could I be experiencing an unsatisfactory level of potassium again? Thank you.
