Monique, you are absolutely right. We have seen the same type of situation in in several CF patients, because they are so at risk for candida overgrowth due to chronic antibiotic use. "Pulverize that yeast!" would be a good motto for CFers. While yeast is viewed almost indifferently by the medical community (except when it's in your lungs), most CF patients know that their health is critically affected by gut yeast overgrowth. Good on ya, Monique!
