Interstitial lung fribrosis, just been diagnosed, what can I do to slow progression, is there any treatment. I have never smoked , I am nearly 65 years young, small food particles were found in my lungs, (nighttime GERD) plus X Rays showed thickening on walls of lower lungs and some stiffening. I want to be proactive and do anything I can to help, I welcome your advice. thank You
