Endoscopy

An endoscopy is a procedure where the inside of your body is examined internally using an endoscope.

An endoscope is a thin, long, flexible tube that contains a light source and a video camera, so that images of the inside of your body can be relayed to an external monitor.

Endoscopes can be inserted into the body through a natural opening, such as your throat, nose or rectum. The procedure is normally carried out when you're awake, and you may be given a sedative to relax you.
