<<Disclaimer: Verify this information before applying it to your situation.>> I am hoping that I get some information from some doctors, but I would like to know if others have a problem when having a barium swallow upper GI. In my case the the fluid runs through the whole upper intestines in a matter of a minute. The gastro radiologist said that this was not normal and usually took a day or so. I seem to feel this is a suggestion that I have still not re-grown the villi that I lost, and there is nothing there to slow down the flow. Hence continued problems with nutrition.. Has anyone gotten these results?
