My GERD creates a regurgitation that blocks my nasal passages and my throat leaving me gasping for air. I thought this was just part of having Pulmonary Fibrosis, but am learning that it is completely separate. My hiatal hernia is the culprit. Look into hiatal hernia regurgitation. Large volume acid reflux is what I am copiously spitting, coughing up, and blowing from my nose. A new medication and following the well-known "rules" of GERD are helping me. A surgery to alleviate hiatal hernia issues is in my future. Acid reflux and pulmonary problems are a terrible mix.
