Introduction
A gastroscopy (also called an upper endoscopy) is a simple, minimally invasive procedure that allows your doctor to look inside your oesophagus, stomach, and the first part of your small intestine. But how do you know when you really need one? Knowing the right time for a gastroscopy can help detect digestive problems early, prevent complications, and give you peace of mind.
Common Reasons You May Need a Gastroscopy
1. Persistent Upper Abdominal Pain
If you have ongoing pain or discomfort in the upper abdomen that lasts more than a few weeks, a gastroscopy can help identify causes such as gastritis, ulcers, or inflammation.
2. Chronic Heartburn or Acid Reflux
Long-term gastroesophageal reflux disease (GERD) can damage the oesophagus lining. Gastroscopy helps assess the severity and detect conditions like Barrett’s oesophagus.
3. Unexplained Nausea and Vomiting
Frequent, unexplained vomiting or nausea can be linked to stomach ulcers, blockages, or inflammation — all visible via gastroscopy.
4. Difficulty Swallowing (Dysphagia)
If swallowing feels painful or food gets stuck, a gastroscopy can help identify narrowing, growths, or inflammation in the oesophagus.
5. Signs of Gastrointestinal Bleeding
Black stools, vomiting blood, or unexplained anaemia could be due to ulcers, erosions, or tumours — urgent gastroscopy is recommended.
Preventive and Screening Reasons
Family history of stomach cancer
Monitoring polyps or Barrett’s oesophagus
Follow-up after treatment for ulcers or tumours
Even without severe symptoms, people with high-risk factors may need regular gastroscopy screenings.
