Hi Searchin'! Welcome to the GERD board!
I recently joined HealingWell in Dec. and have found the most wonderful people here!
I personally do not have bad breath, but wouldn't doubt that could be a side effect from acid reflux.
As for the 'acid fumes', I'd imagine you could have that. I rarely have bile, but often have heartburn.
I also think that you can have acid reflux even with your LES sphincter working perfectly, although when it DOESN'T work well, you're liable to feel much worse (as I'm sure you know!).
I'm not sure how long it takes Barrett's Esophagus to develop. I know that if you have GERD, you are more likely to get Barrett's, but on the same note, you can have GERD forever and NOT get BE, too.
As far as I know, GERD & Acid Reflux are one in the same.
And I am probably considered 'skinny' (5'6", 120 lbs), and I've had GERD since I was 15 (8 years).
Hope this helps! :)
And days go by
I can feel them flying
Like a hand out the window in the wind
And cars go by
Yeah it's all we've been given
So you better start living right now
Cause days go by
