I have had a bad cough and acid reflux for about 3 weeks. The cough and the reflux caused me to throw up. Over the last week all have increased and I have lost my appetite completely. I have been to my doctor twice - Last Monday and Wednesday. CBC blood panel was fine. Additionally, I went to Gastro doc on Thursday who ordered more labs. Potassium - 2.7, sodium, magnesium all low. Doc called me in and given 2 bags potassium and saline. I went back Friday for more. Last time I threw up was early Friday morning. I seemed to be a little better yesterday but now I just feel worse again. I ve seen a total of 5 doctors this week and all give me contradictory information. I have been prescribed 10 medications this week, outside of what has been administered at urgent care for chest pain and nausea I am 48, female. I live in Bakersfield, California and my insurance is Kaiser. I m also asthmatic and it seems odd that nobody has taken a chest X-ray. My main question is does a heavy cough accompany low potassium?
