Hello egayle, 3 separate diagnoses (GERD, MAC and Bronchiectasis) and all 3 could be inter-related, a person could very well have all 3, and wonder what order they occurred. Several months ago I posted a link to a good video from NJH, here it is again https://www.youtube.com/watch?v=BZwM3fsTIIY&feature=youtu.be **** I also read that book by Dr Jamie Koufman years ago when all I had was a chronic DRY cough, it was very informative, highly recommend to any one with a chronic cough. In my case I believe the LPR (GERDS) came first then the bronchiectasis and finally the MAC, but who knows for sure. Bill
