Hi I am 57 years old. I had weight loss surgery a year ago so my eating habits have changed drastically. I was recently sick with what I believe was stomach bug with severe diarrhea and vomiting. I am finally feeling better after taking Zofran and I m modicum and drinking pedialite. But now I have shortness of breath when talking. My voice actually turns into a whisper. Once I cough I can talk a little more before the same thing happens. I still have no appetite. Could this be due to lack of some vitamin since I am not really eating?
