How often do you need to do an egd. had one august, 2022 and nothing was found but i have been burping up liquid every month or so. my gastro has been doing this for thirty years and he said everything looked great. did biosy for celiac and stomac?

You have gastro-esophageal reflux. It's good your EGD and biopsies normal; they shows nothing serious explains this problem. It is unlikely another EGD is necessary. It should be easy to control the symptoms, probably with some combination of acid blocking medication, antacids, and perhaps sleeping position if the problem is mostly at night. Keep working with your gastroenterologist.
