Upper GI endoscopy is a procedure that uses a lighted, flexible endoscope to see inside the upper GI tract. The upper GI tract includes the oesophagus, stomach, and duodenum—the first part of the small intestine.
To prepare for upper GI endoscopy, no eating or drinking is allowed for 4 to 8 hours before the procedure. Smoking and chewing gum are also prohibited.
Patients should tell their doctor about all health conditions they have and all medications they are taking.
Before upper GI endoscopy, the patient will receive a local anaesthetic to numb the throat.
