What Is a Gastroscopy?
A gastroscopy, also known as an upper endoscopy, is a diagnostic procedure used to examine the lining of your upper gastrointestinal (GI) tract, which includes your oesophagus, stomach, and the first part of your small intestine (duodenum). This is done using a thin, flexible tube called a gastroscope, which has a light and camera at its tip.
A specialist doctor performs the test called a gastroenterologist, who is trained in diagnosing and managing digestive system disorders. The procedure is usually done at a hospital or specialised clinic and typically takes 15 to 30 minutes.
When should you see a doctor about your digestive health?
If you’ve been experiencing ongoing digestive symptoms, your first step should be a visit to your GP (general practitioner). Your GP will assess your symptoms and medical history and may refer you to a gastroenterologist if they believe further investigation is needed.
Why might you need a gastroscopy?
A gastroscopy is not something your doctor will suggest lightly. It’s usually done to investigate a variety of persistent or unexplained digestive symptoms. These may include:
- Ongoing upper abdominal pain or discomfort.
- Difficulty swallowing (dysphagia).
- Persistent nausea or vomiting.
- Unexplained weight loss.
- Acid reflux or heartburn that doesn’t improve with treatment.
- Anaemia (which could be linked to internal bleeding).
- Suspected ulcers or tumours.
It may also be used to monitor an existing condition, such as Barrett’s oesophagus, or to investigate the cause of abnormal imaging or blood test results.
What happens during the procedure?
Before the procedure, you’ll be asked not to eat or drink for a few hours. A mild sedative may be given to help you relax, and your throat might be numbed with a spray to ease the insertion of the tube.
Once the gastroscope is inserted through the mouth and into your stomach, the camera sends images to a monitor, allowing the gastroenterologist to see what’s happening inside. Small tissue samples (biopsies) can be taken for further testing if necessary.
Is a gastroscopy painful?
Most people find a gastroscopy slightly uncomfortable but not painful. The sedation helps ease any anxiety or gagging. You might feel bloated afterwards due to air pumped into the stomach during the procedure, but this usually settles within a few hours.
Are there any risks?
A gastroscopy is considered a very safe procedure. However, as with any medical procedure, there are some risks, such as:
- A sore throat for a day or two.
- Mild bloating or cramping
- In rare cases, bleeding or perforation (usually when a biopsy or treatment is done).
Your gastroenterologist will explain all the possible risks beforehand and ensure you’re well informed.
Taking the next step
Digestive discomfort or unexplained symptoms should never be ignored. While occasional heartburn or bloating is common, persistent symptoms may indicate something more serious. Your GP is your first point of contact, who will determine whether a gastroscopy is necessary and refer you to a specialist for further evaluation.
If something’s not sitting right with your digestive health, don’t wait. Find a healthcare provider and book a consultation today.
