What Is a Gastroscopy?
A gastroscopy is a medical procedure that allows us to examine the upper part of your digestive system—the oesophagus, stomach, and the beginning of the small intestine (duodenum). Using a thin, flexible tube called a gastroscope, which has a light and camera at its tip, our specialists can view detailed images of these areas to identify any abnormalities. This procedure is minimally invasive and provides valuable insights that other tests might not reveal.
What Are They Used For?
Gastroscopies are performed to investigate symptoms such as persistent upper abdominal pain, nausea, vomiting, difficulty swallowing, or unexplained weight loss. They are essential in diagnosing conditions like ulcers, gastritis, gastro-oesophageal reflux disease (GORD), coeliac disease, and detecting infections like Helicobacter pylori. In some cases, therapeutic interventions—such as removing polyps, treating bleeding lesions, or stretching narrowed areas—can be carried out during the procedure, providing immediate treatment.
What Are the Effects?
Gastroscopy is generally a safe procedure with a low risk of complications. Most patients experience minimal side effects, which may include a mild sore throat, bloating, or a feeling of fullness due to the air introduced during the examination; these sensations typically resolve quickly. Serious complications are rare but can include reactions to sedative medications, especially in individuals with underlying heart or lung conditions. Very rarely, there may be bleeding or a perforation (tear) in the lining of the upper digestive tract, which might require further treatment. Our team prioritises your safety and comfort, taking all necessary precautions to minimise risks and ensure a smooth recovery process.
