What are the benefits of diagnostic endoscopy?

A diagnostic endoscopy allows specialists to check for abnormal tissue, irritations, ulcers and inflammation of internal organs. An endoscopy can also be used to extract tissue samples from the body (biopsy) or insert dye into a particular organ to create a clearer view under x-ray.

What happens during a diagnostic endoscopy?

Preparing for a diagnostic endoscopy

Before having an endoscope passed through the mouth, you must avoid food for several hours as food in the stomach can obstruct the consultant's view.

You are usually given laxatives before an endoscope is inserted into the rectum and colon.
