My mother in law has been told that she not only got yeast in her lungs (aspergillus) from Advair but yeast was also found her gut, and her pylori valve stopped working and she almost had to go on a permanent feeding tube and everything made her sick. When they cut her open to insert the tube they found the yeast. I have something going on that includes terrible headache, nausea, vomiting and loose bowel. I can't say at this point for certain it is the advair but I have been taking it for over 15 years daily. These symptoms occur 2-3 times a month and wipe me out for a full day.
