Upper gastrointestinal endoscopy for investigation of reflux, indigestion, heartburn, and upper GI symptoms. Performed by a GESA-certified endoscopist under sedation.
A gastroscopy (also called an upper GI endoscopy) is an examination of the oesophagus, stomach, and first part of the small intestine (duodenum). A flexible camera is passed through the mouth to allow direct visualisation of the upper digestive tract. It is the most accurate way to investigate persistent upper GI symptoms and can diagnose conditions that are not visible on imaging.
During the procedure, biopsies can be taken and treatments performed — such as stopping bleeding or dilating a narrow area. The procedure is performed under sedation and is well tolerated.
Ongoing acid reflux symptoms despite medication. Gastroscopy checks for oesophagitis, Barrett's oesophagus, or hiatal hernia.
Persistent pain or discomfort in the upper abdomen that doesn't respond to standard treatment.
Feeling of food getting stuck or difficulty swallowing. Gastroscopy can identify strictures, inflammation, or other causes.
Unexplained iron deficiency anaemia, vomiting blood, or dark stools. Gastroscopy can identify the source of upper GI bleeding.
If you're experiencing any of the following, a gastroscopy may be recommended:
GESA Certification: Our endoscopist holds the GESA (Gastroenterological Endoscopy Society of Australia) certification — the highest standard for endoscopic practice in Australia, requiring advanced training and ongoing quality assurance.
Gastroscopy is a day procedure. You'll be sedated for comfort, and the examination typically takes 10–20 minutes. You can go home the same day.
No bowel preparation is needed. You'll need to fast for 6–8 hours before the procedure. Regular medications can usually be continued — we'll advise you specifically during your consultation.
Performed under sedation (twilight sleep). A local anaesthetic spray may be applied to the throat. The endoscope is passed through the mouth into the oesophagus, stomach, and duodenum. The endoscopist examines the lining, takes biopsies if needed, and can perform treatments during the same procedure.
Rest for a few hours. You'll need an adult to drive you home. Most people feel fine the next day and can resume normal activities.
Initial findings discussed with you before you leave. Detailed report and biopsy results sent to your referring doctor within a week.
If abnormalities were found, we'll discuss the findings and recommend a management plan — which may include medication, further investigation, or surgical referral.
Gastroscopy and colonoscopy can be performed together in one session. This means one preparation, one anaesthetic, and one recovery period.
