question: Hi, may I answer your health queries right now ?  Please type your query here...I was on blood pressure medicine for around 4 years Hyrdrothrochlrozide? about 2 months ago I began feeling lightheaded all day, went to Dr and he took me off, did blood work and my potassium was 3.1, put me on potassium pills, week later the same levels, so he double the  amount, levels went up to 3.7, went back 2 weeks later to check levels again and have dropped to 3.1 again, why do they continue to stay low when on the potassium pill? Thanks
