I didn't have a gastric emptying test, but I did have a barium swallow. And my gi doc didn't find anything abnormal about the test, but they did diagnose me with gastroparesis. So I would say it is possible. And to be honest, push until you get an answer that makes sense. Because it's better to know and have a plan

You may have motility issues in other parts of your GI tract instead of the stomach. That’s very possible and does happen to people. It wouldn’t quite make sense to be diagnosed with gastroparesis and having your gastric emptying study be normal though. It wouldn’t have been able to push your toast through any quicker than anything else. I had the water version of it and I can’t even empty water at a normal rate. I would look into sitz marker and other motility testing to see what other parts might be the culprit
