Is it possible to have a normal gastric emptying study and still have gastroparesis? In the summer, I had one done, but they only gave me eggs and water because I am gluten free and didn't know I had to bring my own toast. Could this have altered the results? The results showed that 7% of the egg was still in my stomach after 4 hours. My symptoms have gotten much worse since the summer. I've gotten a diagnosis of POTS and I've been told I have GI dysmotility, but I'm wondering if it could be gastroparesis, as it is a common comorbidity with POTS. TIA <3
