What is an Endoscopy?

An endoscopy is a test that checks if your tummy is healthy.

A small camera on a tube is put into your mouth, and goes down to your tummy.

An endoscopy is done at a hospital, but you can normally go home on the same day.

A doctor or nurse will tell you what will happen before your appointment.

Before you have an Endoscopy

You must stop eating 6 hours before your appointment.

You must stop drinking milky drinks 6 hours before your appointment.

You must stop drinking clear fluids 2 hours before your appointment.

Clear fluids include water, lemonade, black tea and coffee.

Having nothing to eat or drink is very important.

If your tummy is not empty, you could choke.

If your tummy is not empty, the doctor might not be able to see it clearly with the camera.

What happens at my appointment?

You will be given a spray to stop the camera from hurting your throat.

The doctor or nurse might put a thin tube into the back of your hand.

Medicine will be given to you through this tube.

The medicine will make you feel sleepy.

You might not remember much about your appointment because of this medicine.

You will be asked to lie on your side.

The doctor will put the camera in your mouth and down your throat.

Air will be blown into your tummy and it might make you burp.

This is normal, so don’t feel embarrassed.

If it feels strange or sore you can ask the doctor to stop.

Ask 3 questions
