Newbie,
I completely understand the research you have done. But I can say without a doubt, along with many other people on this board that there is indeed a link between LPR and bad breath. The link is really commonsense: if you have stomach acid which aren't suppose to travel up your esphogus into your mouth you will indeed have bad breath and sinus irritation(congestion and PND) which makes the smell worse. Imagine everything you eat on a daily basis traveling back up to your mouth after being digested in your stomach sounds excellent right?
I did not have bad breath or any type of hygiene related issues until I developed LPR. Now, no matter what I do I can't get seem to get rid of it at all. I had a doctor, the first one I saw, she was fresh out of medical school and she assured me the BB was not related to LPR. I left her office confused and perplexed but now that I am seeing specialists, people who deal with LPR and GERD specifically they agree that BB is certianly a symptom. As are ear infections.
I am not sure about the pepcid comment that sounds interesting and I may ask my doctor about it, but for all the other people out there who like me didn't have an odor at all I took that comment very personal. I suffer on a daily basis with this and I am 100% sure there is a link I have the proof.
