Endoscopy is a procedure involves using a camera to look inside the body.
The camera (endoscope) is a long, thin, flexible tube that has a light and camera lens at one end. It is assed into your body through a natural opening, such as your mouth, and images of the inside of the body are shown on a television screen.
Your GP may refer you for an endoscopy if you're having certain symptoms and there are different types of endoscopy that look at different parts of the body. The type of endoscopy you have will depend on your symptoms.
