Hi Irish Boy,
I'm one of those members Bill was talking about...I had terrible lung problems for a very long time. During that time my PCP and asthma docs both thought that reflux was the culprit. I do have bad allergies, but the amount of trouble I was having indicated that it was more than an allergy issue.
Long story short, after 4 years of visiting my GI doc he finally decided that might possibly benefit from the Nissen surgery. I had the surgery in 2009, and within 2 and a half months my lungs had improved tremendously.
I, for one, didn't do all that well on PPI's. They helped my symptoms to some degree, but I still had breakthrough reflux, and my lungs continued to deterioriate.
I still have allergic asthma and am treated with a low dose of steroid inhaler, but my lungs are healthy today. Yes, GERD can create havoc with your lung tissue. My allergy/asthma doc is frustrated with GI docs because they don't understand that a very small amount of reflux can create a big problem for lungs. He says that GI docs are only concerned with the amount of reflux that can cause esophageal damage, and aren't really aware of how reflux that they might dismiss as minimal can cause great harm to lungs.
As I recall, I was told that it takes 2 weeks for PPIs to reach full effectiveness. One PPI dose a day doesn't seem much for someone with as severe a problem as you describe. Perhaps they're starting with a lower dose, and will gradually increase it if needed.
Good luck! I hope you find help soon.
