@bbeers I was diagnosed with mild bronchiectasis and MAC five years ago by a pulmonologist who has since moved away. I had coughed up blood, but had no other symptoms and great spirometer readings. The pulmo had me visit an ID doctor, who monitored my health, but agreed that I didn't need treatment. I started on 7% saline after reading about it here. The first ID doctor retired and my new one, who treats MAC patients, told me to keep nebulizing the saline if I wanted, but that I didn't need to see him again unless I had some symptoms. He felt that many people were getting "treated" who didn't need to be, and that sometimes the "treatment" is worse than the disease. (I am 76. I exercise, walk about 2 miles/day, and try to eat healthy food.)
