The GerdQ is a six-item self-administered questionnaire assessing symptoms experienced over the past seven days. It combines typical reflux symptoms, symptoms that make the diagnosis less likely, and two impact questions. It can help structure the assessment of gastroesophageal reflux disease, without replacing clinical diagnosis or investigations when indicated.

Terms of contract
Self-assessment questionnaire completed by the patient based on their symptoms over the past 7 days. Use the official version licensed by AstraZeneca, without altering the wording or response options. Simultaneously check for red flag symptoms (dysphagia, gastrointestinal bleeding, unexplained weight loss), which warrant a medical evaluation regardless of the score.
