a short video below.
You can stay in your own clothing and your nurse will take you to the room where you will have the gastroscopy.

This may make you feel full and want to belch.
Your specialist may pass an instrument through the endoscope and take a very small piece of the gut lining (biopsy). This should not be painful.
