There seems to be an unfounded fear of gastroscopy here in Austria so people often choose to get fluoroscopy during barium swallows (euphemistically called "stomach x-ray") for check-up on common issues like gastritis, ulcers, etc.
It always boggles the mind how doctors will habitually do fluoroscopy first (approx. 6mSv per session) when gastroscopy as a diagnostic tool is often 100% as effective while being mostly harmless and offering the option for a small biopsy for further diagnosis.
I've had gastroscopy multiple times myself, it's really no big deal and doesn't warrant getting a (general) anesthesia in my opinion but YMMV.
