What mg said, endoscopy is a term used to describe the field of medicine and gastroscopy/colonoscopy etc are the procedures. They will be able to tell you if its caused by a hiatus hernia or other anatomical issue, or might require sending of a biopsy for viewing. They might give you a brief overview afterwards. But usually gp into more details and answer any questions at a specialist appt. Hope that helps.

Good luck with everything, and know that we will be thinking of you and your DD.
