May I ask if Upper GI test using barium can also be used to diagnose slow emptying problem as an alternative for the gastric emptying study (using radioactive)?

My GI doctor does not think I have problems with gastroparesis because normally, patients would vomit after eating. Though, I dont vomit after eating but I feel bloated after eating. I eat frequent, small amounts of food, but even with this, I still feel so full. When I start feeling bloated, my breathing becomes more difficult. Its a cycle.

My abdomen cat scan was normal. NOrmally, she said she would have given me an endoscopy but since I just had a bronchoscopy, she gave me request for upper GI test intead. While searching on the net, I found this article about alternative tests for gastric emptying test and upper GI was one.

It is important that I should gain more weight. I am thin for my height and for patients with Mycobacterium Avium, it is really required to add more calories.

Thank you.
