Well tonight Azer's main GI doctor called saying that she reviewed the results of his impedance test. She said 50 or under events of reflux is normal. Azer had over 90. A large percentage of those events were when he was refluxing all the way up his esophagus, meaning he is very likely to be unknowingly aspirating. She believes the next step is a Nissen surgery. She is setting up an appointment for him to meet with a surgeon that is familiar working with CF patients.
