2)      Then a thin flexible tube about the width of a finger which has a camera attached is passed through your mouth and into your gullet.

3)      The camera allows the doctor to view the inside of the gullet, the stomach and inside the first part of the bowel.

4)      Often they will take pictures so that they can see if there has been any disease progression or to keep a track of the changes.  

5)      The doctor can also take samples from your gut to help find out what might be causing any problems.
