Potassium / Sodium Levels
For the last 2 years my potassium is coming in too high and my sodium is coming up too low in blood tests. I have hypo-thyroid but but my TSH levels are where they should be with the meds. I have no symptoms and feel fine. My doctor seems very concerned and is sending me to an Endo for the first time later this month. Could you tell me what I might have and what to expect from the Endo?
