Sue, first, we are all different, of course and genes play a big role. I am now 80. I was diagnosed with MAC and bronchiectasis in 2012 after questioning my mother’s pulmonologist about the possibility since my mom was diagnosed in her early 70’s. My mother lived until she was 89. She never received the now accepted treatment but rather with the fluoroquinolones and then azithromycin, I believe. I received the vig 3 treatment over 18 months and my MAC went into remission. I am quite vulnerable to lung issues so have a harder time w eg chest colds and covid knocked me back last summer. This past Fall I participated in an 18-session pulmonary rehab clinic that was outstanding. I learned how to breathe better. I carry a pulseoximeter when i go walking about 4 times a week and manage 4 miles at about 22 minutes per mile. Being active and exercising, I believe helps a lot. I just wanted to give you encouragement to be compliant with your pulmonologist’s instructions during treatment. - Jennifer
