Gastroscopy Screening

A gastroscopy is a diagnostic procedure to examine the lining of your oesophagus, stomach, and small intestine. An endoscope, which is a long, thin, and flexible tube with a small camera attached, will be inserted through your mouth and into these organs.

Who Should Go For a Gastroscopy?

Gastrocopy - scan stomach for abnormalitiesYour doctor may recommend you to go for a gastroscopy to:

  • Get screened for stomach cancer
  • Check your stomach for polyps or ulcers
  • Remove foreign objects
  • Confirm the cause of certain symptoms, such as:
    • Difficulty when swallowing
    • Reflux and heartburn symptoms
    • Prolonged upper abdominal pain
    • Nausea and vomiting

How to Prepare for Your Gastroscopy

You will be required to fast before your gastroscopy. This is to ensure your stomach is empty during the procedure, allowing it to be visualised clearly. If your stomach is not cleared completely, the doctor will not be able to get a complete view of your stomach. In such cases, you will need to reschedule your gastroscopy.

If you are on medication, your doctor may request for you to stop taking them beforehand. Your doctor will give you further advice, depending on your situation.

What to Expect for Your Gastroscopy


The gastroscopy is usually performed as a day surgery procedure, which takes about 10 - 20 minutes. We will sedate you and spray your throat with a light anaesthetic spray to numb your throat and ease any potential discomfort. During the procedure, the doctor will insert the gastroscope through your mouth and into the stomach.

After your gastroscopy, you will be moved to our Day Surgery ward for observation until your sedative wears off. After that, we will serve you light refreshments, and your doctor will visit you to explain about your gastroscopy results.
