Gastroscopy Screening Singapore


What is Gastroscopy in Singapore?

Gastroscopy in Singapore is a procedure where a thin, flexible tube called an endoscope is used to look inside the oesophagus (gullet), stomach, and first part of the small intestine (duodenum).


It’s also sometimes referred to as an upper gastrointestinal endoscopy.


The endoscope has a light and a camera at one end. The camera sends images of the inside of your oesophagus, stomach, and duodenum to a monitor.

Why a Gastroscopy may be used?

A gastroscopy can be used to:

  • investigate problems such as difficulty swallowing (dysphagia) or persistent abdominal (tummy) pain

  • diagnose conditions such as stomach ulcers or gastro-oesophageal reflux disease (GORD)

  • treat conditions such as bleeding ulcers, a blockage in the oesophagus, non-cancerous growths (polyps), or small cancerous tumours


A gastroscopy used to check symptoms or confirm a diagnosis is known as a diagnostic gastroscopy. A gastroscopy used to treat a condition is known as a therapeutic gastroscopy.


Gastroscopy in Singapore is recommended for those who have frequently ached into the stomach & small intestine and they have a complete range of equipment and comprehensive treatment for Gastroscopy.

What is the gastroscopy procedure?

A gastroscopy often takes less than 15 minutes, although it may take longer if it’s being used to treat a condition.


It’s usually carried out as an outpatient procedure, which means you won’t have to spend the night in the hospital.


Before the procedure, your throat will be numbed with a local anesthetic spray. You can also choose to have a sedative if you prefer. This means you will still be awake but will be drowsy and have reduced awareness about what’s happening.


The doctor carrying out the procedure will place the endoscope in the back of your mouth and ask you to swallow the first part of the tube. It will then be guided down your oesophagus and into your stomach.


The procedure shouldn’t be painful, but it may be a bit unpleasant or uncomfortable at times.

What are the risks?

A gastroscopy is a very safe procedure, but like all medical procedures it does carry a risk of complications.


Possible complications though extremely rare that can occur include:


  • a reaction to the sedative, which can cause problems with your breathing, heart rate and blood pressure

  • internal bleeding

  • tearing (perforation) of the lining of your oesophagus, stomach or duodenum
