I had terrible tasting burps in my teens, vomiting in the night in my thirties, and typical heartburn in my forties. I'm certain now it was gerd from the beginning.
Balancing a healthy esophagus with healthy bones can be difficult.
I hope you get some good feedback from this site. I'm sorry I don't have further information, but you can be certain there are other young adults with gerd out there.
Someday I WILL breathe easier.
