Gastroscopy

A direct examination of the oesophagus, stomach and upper small bowel.

Overview

A gastroscopy allows direct examination of the oesophagus, stomach and duodenum using a thin, flexible camera, commonly used to investigate indigestion, reflux, swallowing difficulty or unexplained weight loss. Mr Alan Woodward performs gastroscopy across South Wales and Bristol, using his broad surgical and endoscopic experience to guide the right next steps for each patient.

How it’s performed

Gastroscopy involves passing a thin, flexible endoscope through the mouth and down into the oesophagus, stomach and duodenum to examine the lining directly, with biopsies taken if needed.

Recovery & Aftercare

Gastroscopy is typically a quick outpatient procedure, and most patients go home within an hour or two once sedation or throat spray has worn off. A mild sore throat can occur briefly afterwards. Findings are often discussed straight after the procedure, with biopsy results, if taken, following within one to two weeks.

Is Gastroscopy Right for Me?

The best way to find out is a consultation. Mr Woodward will review your symptoms, explain what to expect and recommend the right approach for you.

Frequently Asked Questions

What is a gastroscopy used for?

A gastroscopy examines the oesophagus, stomach and duodenum to investigate symptoms such as persistent indigestion, reflux, swallowing difficulties or unexplained weight loss. It can also be used to monitor known conditions or take biopsies where needed.

Most patients tolerate gastroscopy well, particularly with throat-numbing spray or light sedation available. Some gagging or bloating can occur during the procedure, but it is generally brief and well managed.

The examination itself usually takes only five to ten minutes, though the full appointment, including preparation and recovery, typically takes around an hour. Sedated patients may need slightly longer before they are ready to go home.

Yes, fasting for several hours beforehand is required so the stomach lining can be examined clearly. Specific instructions on timing are provided ahead of the appointment.

Patients who have sedation should not drive, operate machinery or sign important documents for the rest of the day and should arrange for someone to accompany them home. Those who only have throat spray can usually drive home once fully alert.

Initial findings are often discussed immediately after the procedure, while biopsy results, if taken, typically take one to two weeks to come back. Mr Woodward’s team will explain the next steps clearly at every stage.
