The Gas and Bloating Diary Instrument (GABDI) is a list of patient-reported symptoms that are used for the evaluation of abdominal problems associated with gas and bloating. This problem affects 15-20% of the US population. GABDI comprises of 11 commonly experienced symptoms, and each one is assessed for its intensity, frequency, and duration. Because the incidence and nature of these symptoms vary day to day, and it is often difficult to accurately remember them, there is a significant recall bias. Hence, it is important to prospectively, accurately, and in a timely manner document and assess these patient-reported abdominal symptoms for use in clinical trials, and assessment of these patients.
