How is acid reflux diagnosed?

Most people are diagnosed with acid reflux or GORD by their GP, on the basis of their typical symptoms and their response to treatment. Further tests may be needed if:


  • Symptoms are severe
  • Symptoms do not improve with treatment
  • Symptoms are not typical of GORD
  • There are "flag symptoms" (e.g. difficulty swallowing, worsening symptoms, unexplained weight loss, chest pain or shortness of breath on exertion)

If further investigation is required a gastroscopy (also sometimes referred to as an "OGD") is usually the next step. This is where a thin, flexible telescope is passed down the oesophagus into the stomach. This can help to rule out more serious causes of reflux symptoms, particularly stomach cancer.
