I agree with having a gastric emptying study done. I am also wondering about your gallbladder and whether it is functioning properly. There is acid reflux and bile reflux so curious if they specified. They are treated with different medications. But I feel like you would have way more symptoms with GERD, such as burning in throat and a terrible taste in your mouth especially in the morning after sleeping flat. Anyway, I am no medical professional but just going off my own experiences. Best of luck and keep us posted.
