What is an Upper GI Endoscopy?

An upper GI endoscopy is a procedure where the doctor examines the lining of the upper part of your gastrointestinal tract, which includes the oesophagus, stomach, and duodenum. Your doctor will use a thin, flexible tube called an endoscope and will view the images on a video monitor.

What is the Purpose of an Upper GI Endoscopy?

An upper GI endoscopy is conducted to check for known diseases affecting the upper GI tract or to help diagnose or detect a variety of conditions, such as:

  • Acute upper gastrointestinal bleeding
  • Dysphagia or difficulty in swallowing
  • Dyspepsia (indigestion) or heartburn
  • Unexplained weight loss or loss of appetite
  • Atypical chest pain
  • Abdominal pain of unknown origin

What Preparations are Required?

As an empty stomach allows for the best images and safest examination, you should have nothing to eat or drink, including water, for approximately 6 hours before the examination.

 

Can I Take My Current Medication?

Some medications may interfere with the preparation for an endoscopy. Please let your doctor know what medications you are taking and if you have any drug allergies.
