An endoscopy is a procedure where the inside of your body is examined internally using an endoscope.
The procedure is often undertaken while a person is awake and a sedative (medication that has a calming effect) may be given to help the patient relax.
The endoscope itself is a flexible tube with a video chip on the end which allows a live video image to be seen on a screen.
Endoscopes can be inserted into the body through your throat or anus, or through a small incision (cut) made in the skin.
