Gastroscopy is a procedure used to examine the oesophagus, stomach and duodenum via a flexible “tube” equipped with a camera and administered through the mouth.
It shows up any lesions and allows samples to be taken for analysis under the microscope with a view to arriving at a diagnosis.

Technical details of the examination:



Nil by mouth for 6 hours before the examination.
Nil by mouth = nothing to drink, eat or smoke.
Please inform the doctor of any allergies you have and drugs you are taking; some must be stopped before the examination.
Before the examination, please remove glasses and false teeth.


On average, the examination lasts 10 minutes.
The whole procedure, however, may take 2 hours.


The examination is painless.
You will not experience breathing problems, as the tube does not go into the lungs.
You must be accompanied when you return home, because of the sedative given before the examination.
