Gastroscopy

A gastroscopy is a visual examination of the oesophagus (‘food pipe’), stomach and duodenum (first part of the small intestine). 

It is also known as an upper endoscopy. 

It is performed using a thin flexible tube containing a fibreoptic light and camera (known as a gastroscope).

Why is gastroscopy performed?

Gastroscopy can be performed to investigate symptoms such as indigestion, nausea, swallowing difficulties, abdominal pain and change in bowel habit. 

It may show inflammation, ulcers, polyps or other growths. 

Tissue samples (biopsies) can be taken of any unusual findings and polyps can be removed. 

Testing can also be performed for conditions, such as coeliac disease or certain food intolerances, in appropriate clinical contexts.

Before the gastroscopy

You will need to have an empty stomach before gastroscopy.  You will be advised how long to fast (not eat or drink) before gastroscopy. 

If you take medications, have allergies or other medical conditions, Dr Zhu will provide individualized advice regarding this prior to the gastroscopy.

After the gastroscopy

Gastroscopy is performed as a day procedure.  It is usually performed with light sedation administered by an anaesthetist.

You are usually allowed to eat and drink after the procedure. 

However, you should not drive, travel alone on public transport, operate machinery, sign legal documents or drink alcohol for 24 hours after the procedure.

Dr Zhu will discuss the findings of your procedure with you on the day and will arrange further follow up as appropriate.

Dr Zhu can determine if this procedure is appropriate for you and individualise it based on your medical profile.
