Beyond Gastroscopy: Advanced Digestive Testing Options

• Capsule endoscopy – a small, swallowable camera that captures images of the small intestine, an area not reached by standard gastroscopy or colonoscopy 

• Oesophageal pH monitoring – measures acid exposure to help assess reflux that may not be visible on gastroscopy 

• High-resolution oesophageal manometry – evaluates how well the oesophagus muscles are working, particularly for swallowing concerns 

• Breath testing – used to investigate conditions such as small intestinal bacterial overgrowth (SIBO) and certain food intolerances 

These tests may be recommended when symptoms are ongoing but not fully explained by initial investigations, or when a more detailed understanding of digestive function is needed. 

Rather than defaulting to a single test, Intus specialists take a personalised approach, selecting the test that is most likely to provide a clear and useful answer. 

This helps avoid unnecessary procedures and ensures patients are guided through a diagnostic pathway that is both efficient and tailored to their individual needs. 

If you are experiencing persistent digestive symptoms, understanding that there is more than one testing option can be an important step towards finding the right answers.
