An endoscopy is a procedure where the inside of your body is examined using an endoscope. An endoscope is a long, thin, flexible tube that has a light source and a video camera at one end. Images of the inside of your body are relayed to a television screen.

Endoscopes are inserted into the body through a natural opening, such as the mouth and down the throat, or through the anus (the bottom).

Some of the most commonly used types of endoscopes include:

Colonoscopy – used to examine your large intestine (colon)
Gastroscopy – used to examine your oesophagus and stomach
