I've been having loud burps very frequently since a year ago. At the worst, I felt food was coming out together with the burps. At the same time I have been having pretty bad stomach discomfort which sometimes gives me backache. My doctor suspected it is gall stones but my ultrasound result didn't show any gallstones. Any one having similar symptoms? Your help is greatly appreciated!

Might be GERD (acid reflux)
I would ask your doctor.

Hi! I have severe gastroparesis and GERD. Gastroparesis is delayed stomach emptying and can cause GERD or make existing GERD worse. The symptoms are bloat, nausea, burping, feeling full after only a few bites, etc. Due to the delayed emptying, it can cause acid, food, bile, etc to reflux all the way up to the throat, go into the lungs, etc. There is a gastric emptying study to diagnose the gastroparesis. To dignose the GERD, there are several tests, upper GI, upper endoscopy, 24 hour PH manometry. IF you have gastroparesis, the medicine, Reglan can help. Good luck!
