I just had an endoscopy at the end of October and am waiting on results from biopsies that were taken. I too am going through chronic nausea and vomiting, and my gastro doctor thought it might be because of my hiatal hernia but from my endoscopy, it looks like my hernia got smaller! So now it's onto more tests from my dietitian and hoping the biopsy results give some sort of hint as to the cause of my ongoing nausea and random vomiting.

I had so many tests done to try to figure out my chronic nausea, including an endoscopy. All came up "clear" or "fine" but I deduced on my own that I had to have at least a sensitivity to gluten bc I saw a video about "tight junctions" that basically explained exactly what I had been going thru...somehow none of the doctors knew anything about this. They wanted to write off my other symptoms off as just heartburn -_- once I started taking digestive enzymes & probiotics daily, I was able to eat almost whatever I wanted to again. Unfortunately, one of the medications I'm taking does cause nausea, so I do still have to take ondansetron daily. I have quite the phobia of vomiting, so I guess I'm lucky it never came to that...
