Gewarn, I'm going to look into the gastric delay as well; i have terrible bloating, fullness, and LPR.
You are correct in that PPIs do reduce the stomach acidity over time, and this is not helpful to us (even though they reduce the *symptoms* of heartburn). So, I wonder if you are not feeling the *pain* of the reflux, but the LPR is showing you that it's still happening...
I would recommend getting off the PPIs, and doing some more investigating. I will also say that I'm a newbie at this, but after working with some nutritionists and doing some research, it does seem that PPIs are not the solution--just a temporary bandaid.
Let us know what you find out!!
