Endoscopy is a test to look into the esophagus, stomach and first part of small intestine. Endoscope is a thin, flexible tube passed through the mouth and its tip has a camera so that the operator can see inside your gut.

What happens during endoscopy?

The doctor usually sprays the back of your throat with local anesthetic spray to make it numb. You are asked to lie on your side on a couch and put a plastic mouth guard between your teeth. You are asked to swallow the first section of the endoscope which is pushed down your food pipe. The video camera records pictures and sends them to a screen. The doctor may take biopsies of the inside lining of the gut depending on your condition. This is  painless and samples are sent to the laboratory.

What preparation do you require?
