Hi Denise, Thanks for writing in. I understand your concern. As far as the Bartter s syndrome is concerned, you should be talking to a nephrologist for drugs like spironolactone and angiotensin receptor antagonists like losartan. This along with potassium supplements should help you maintain your potassium levels. Also, it is recommended that you take plenty of water and potassium rich foods like tomatoes, bananas, orange juice. It is extremely important that you keep yourself well hydrated, especially when you exercise. Regards
