An OGD enables the doctor to examine the lining of the oesophagus, stomach and the first segment of the small intestine (duodenum). It is sometimes also referred to as a gastroscopy.

This procedure is usually recommended for the investigation of symptoms such as indigestion, frequent abdominal pain or discomfort, heartburn, vomiting, nausea, and weight loss. It is an effective method to check for symptoms or confirm a diagnosis, such as stomach ulcers, stomach cancer or H. pylori bacterial infection.


An OGD is performed in the endoscopy suite, while patients are comfortably sedated. The procedure involves the insertion of a soft, thin, bendable tube with a built-in camera via the mouth, and into the stomach.


It is used to screen for gastric (stomach) cancer and can also detect the presence of a bacteria (Helicobacter Pylori), a known cause of stomach cancer that can be treated with oral medications.


At Melissa Teo Surgery and The Surgical Oncology Clinic, our doctors are experienced in performing OGDs and will ensure that you are cared for, before and after the procedure. Your results will be discussed in detail with you right after the procedure, and any subsequent follow-up consultations needed will be made swiftly.
