the doctor. Has anyone had one or know someone who has and what's involved?
You can find all the information that you are looking for right here:-)http://www.uwmedicine.org/PatientCare/MedicalSpecialties/SpecialtyCare/UWMEDICALCENTER/Radiology/uppergiexam.htm
I've never had one myself but my son has and I can only say that an upper is a lot easier to handle than a lower! All you have to do is swallow some stuff and that's not so bad. Good luck with it!
