@eagle71, I see that you’ve also posted about digestive issues and have recently had a Nissen fundoplication surgery to treat gastroesophageal reflux disease (GERD).

You may be interested in reviewing the very popular discussion started by @gabrielm talking about shortness of breath, many of who mention GERD and more. See here:

I’ll also ask the same question as @tessa2. Has the diagnosis of pulmonary fibrosis been confirmed?
