How nude do you need to be for an Upper GI?
I have had 2 in the last year. One I was required to strip down to my undies, the other I was not. I think it depends on if they want small bowel follow through. The first one they wanted to see the barium in my intestines the second one was just a basic upper GI. I would recommend taking some thin sleep type pants with no metal and maybe they will allow you to wear those.
