Hey Norm, et. al --
Norm, I'm going to write more extensively in a response your previous post. However, I just thought -- has any of your research into the carb "lifestyle" noted results from an endoscopy.
I thought of this -- as I spoke to a patient today who complained of mild-GERD symptoms with occassional night-time GERD. I put her on Nexium = she was symptom free (after 1 day) & referred her for an endoscopy. I received the results today stating that she actually had a Grade-D erosion (from the LA Classification system). I was shocked because she came in virtually pain free and only mentioned any symptoms because her daughter brought it up during her visit.
Additionally -- I did a quick literature check and found an article by Johnston & Fennerty stating that heartburn symptom drastically underestimated erosive severity in the elderly.
That said -- on your diet, I wonder if people are still refluxing (and possibly could be damaging their esophogus) but not feeling symptoms?
