This animated video is an informative video that provides information regarding Upper Gastro-intestinal Endoscopy. An upper GI endoscopy procedure allows your doctor to view the mucus lining of the upper portion of your gastro-intestinal tract. This includes your oesophagus, stomach and duodenum. Upper endoscopy is used to evaluate symptoms of persistent upper abdominal pain, nausea, vomiting, bleeding, or difficulty in swallowing. The procedure is performed using an endoscope which is a long thin flexible tube a light and a tiny video camera attached to the end. The camera transmits the image to a monitor. Uncomplicated upper endoscopy takes 10-20 minutes, your doctor will gently insert the endoscope through your mouth and then slowly and carefully move it down your oesophagus until it reaches your stomach.
