I have acid reflux symptoms, burp a lot to relieve stomach pain, have an endoscopy scheduled next week. What sort of diagnosis should I expect?

DX Dyspepsia.

Bloating
Heartburn
Nausea (upset stomach)
Vomiting
Burping
Often ulcer or gerd present
Avoid Smoking, Excess of NSAID,Reduce stress,Lifestyle change
EGD For H.P & r/o B.
sounds like GERD. You should specifically inquire whether or not there is damage to your esophagus, and what the biopsy results showed if one was done.
