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!
