I was diagnosed with PA 20+ years ago and currently have low ferritin levels (was anemic once before, four years ago). Several years ago I developed persistent heartburn which I had assumed was due to all the meds I take for several health issues. The Dr. put me on prescription Prevacid which did the trick. Now I keep reading about low stomach acid with PA and possibly not being advised to use medications like the one I am on. Is this correct and should I be talking to the Dr. about this? Thanks!
