Gastroscopy

A gastroscopy is a test that lets your doctor look a long way down your throat. They can then see into your foodpipe and stomach.

The doctor uses a long bendy tube with a tiny camera and light on the end.

Why do I need one?

You might need a gastroscopy if you’re having tummy problems. It will also show if aren’t getting enough goodness from your food.

What happens?

It’s really important that your stomach is empty. This way the doctor can see every bit of it clearly. So you have to stop eating and drinking about four hours before the test.

The nurse will put a cannula (a thin, plastic tube) into one of your veins. This is so that the doctor can give you medicine easily during the test.

Your nurse will put cream on your arm to numb it so you won’t feel the cannula going in.

About two hours before the test, you will have some medicine that will make you really sleepy. You’ll either drink this or it might be put into the cannula.

Just before the test starts, the doctor will give you some more medicine. This will make you even sleepier.

You’ll be given some throat spray. This is so it won’t hurt when the doctor puts the tube down your throat.

Your mum or dad can stay with you during the test. Then they’ll go with you back to the ward when the test is finished.

When can I go home?

You’ll probably feel really sleepy after the test. That’s why you’ll have to stay on the ward for a few hours until you wake up properly and have a drink and something to eat.

If you’re not sick and you’ve had a wee, you’ll be able to go home.

You’ll probably still feel a bit dozy when you get home. This will go away once you’ve had a long sleep.
