Given that bronchiectasis and NTM often present differently in each person, I suspect it will be awhile before we see such guidelines. Until then, we practice daily airway clearance using hypertonic saline, exercise, eat nutritiously and restful sleep. Taking steps against exposure to dense sources of NTM (drinking water, GERD/reflux, showers, indoor pools, steam rooms, soil etc) makes sense too. And we need to keep our equipment clean and sterilized. We know a lot already about daily guidelines which we've gleaned from our specialists and each other here and other support forums.

This link has invaluable information about managing bronchiectasis and NTM.

Is there something specific you wonder about? Perhaps about treating NTM with the big 3?

Nothingness. Several of us are monitoring regularly, and will share it as soon as it's available.
