@ann0616 Ann, I think the majority of us in this group has MAC/Bronchiectasis brought on by acid refux/gerd. It is a common cause of bronchiectasis. Just follow the guidelines for dealing with the reflux. One thing that really helps me to avoid reflux is eating smaller amounts of food at a sitting. It is better to eat five small meals a day, or add in a heavy snack to suppliment a smaller quantity at dinner and lunch. Have you tried this already?
