Diagnosis and effective management of gastroesophageal reflux (GERD) need a new approach. The 2009 Montreal Consensus recommended that the clinical diagnosis of GERD should be made on the presence of troublesome symptoms. GerdQ, a patient centered-self assessment questionnaire, is made to assist health care professionals. Also, it is easy to use, no diagnostic test required, for example without previous specialist referral or endoscopy. GerdQ is a well documented questionnaire, developed on the basis of evidence. GerdQ has three potential uses in clinical practice: (1) to diagnose gastroesophagel reflux disease with an accuracy similar to that of the gastroenterological evaluation; (2) to assess the relative impact of the disease on patient's lives and to assist in choice of treatment; (3) to measure response to treatment over the time.
