Gastroscopy: cost, NHS wait & what to expect

Overview

A gastroscopy looks at the lining of the gullet (oesophagus), stomach and the first part of the small bowel using a thin flexible camera passed through the mouth. It can take biopsies and treat some problems.

Why it's done

• Persistent indigestion, reflux or difficulty swallowing
• Unexplained upper-tummy pain or anaemia
• To check for ulcers, inflammation or coeliac disease

What happens

A quick test, usually 10–15 minutes. You can choose throat-numbing spray or sedation. Biopsies can be taken painlessly during the test.

Recovery

• Eat and drink again once any throat numbing wears off
• Do not drive for the day if you have sedation
• Biopsy results take a week or two

Risks & things to consider

• A sore throat for a day
• Small risk of bleeding after biopsies
• Very small risk of a tear (perforation)
• Sedation risks

Alternatives

• A trial of acid-reducing medication first in some cases
• Barium swallow X-ray in specific situations
• Non-invasive tests for H. pylori infection

Questions to ask your provider

• Should I choose throat spray or sedation?
• Does the price include biopsies?
• When will I get my results?
• Do I need to stop any medicines beforehand?
