Hi, thanks for using healthcare magic
With your symptoms of abnormal taste in your mouth, bloating and chest pain
, the endoscopy
may show some changes suggestive of reflux in the stomach or the esophagus
If it does not demonstrate not even minor changes and your symptoms continue then your doctor may consider a trial of medication to see if your symptoms improve.
If they improve on reflux medication
then it is likely the cause of your symptoms.
I hope this helps
