Gastroscopy, also known as oesophagogastroduodenoscopy (OGD), is a safe and highly accurate procedure used to examine the oesophagus, stomach, and the first part of the small intestine (duodenum). At Dr Bernard Lim Specialist Surgery, we specialise in expert gastroscopy services to diagnose and treat a range of digestive conditions, ensuring your long-term health and well-being.
A gastroscopy is a minimally invasive procedure performed using a thin, flexible tube with a camera (gastroscope) that is passed through the mouth to examine the upper digestive tract. It is the most effective method for detecting conditions such as gastritis, ulcers, polyps, and even early-stage cancer.
Inflammation of the stomach lining, often linked to Helicobacter pylori (H. pylori) infection
Open sores in the stomach or small intestine that can cause pain and bleeding
Chronic acid reflux leading to oesophageal damage
Early detection of abnormal growths before they progress

Many digestive conditions can remain undiagnosed until symptoms become severe. Gastroscopy allows for early detection and treatment, preventing complications and improving outcomes.
You may need a gastroscopy if you experience:
You will need to fast for at least 6 hours before the procedure. Inform your doctor if you are on blood thinners.
A local anaesthetic spray is applied to your throat, and mild sedation may be given for comfort.
The gastroscope is inserted gently through the mouth to examine the oesophagus, stomach, and duodenum. The procedure typically takes 10–15 minutes.
If necessary, tissue samples may be taken, or polyps and bleeding areas may be treated immediately.
You can go home the same day (preferably accompanied) once the sedation wears off.
