Normal Values of Ambulatory 24-hour Oesophageal pH-impedance Monitoring in an Indian Cohort of Participants
Normal Values of Ambulatory 24-hour Oesophageal pH-impedance Monitoring in an Indian Cohort of Participants
This study aims to determine normal 24-hour pH-impedance monitoring values, including acid exposure time (AET), in healthy Indian adults. It will help improve GERD diagnosis in India by providing population-specific data. The study will also explore how diet, body position, and nighttime reflux affect acid exposure. Healthy volunteers aged 18 and above will be monitored for 24 hours.
This prospective study aims to establish normal 24-hour ambulatory pH-impedance monitoring values, including acid exposure time (AET), in healthy Indian volunteers. With an estimated GERD prevalence of 8-10% in India, current diagnostic criteria, such as the Lyon Consensus cut-off of 6%, may not be suitable for the Indian population due to differences in AET. The study will investigate the normative values of AET in healthy individuals and examine how factors such as diet, body position, and nocturnal reflux influence acid exposure and reflux episodes. By determining these standard values, the study seeks to enhance the accuracy of GERD diagnosis in India and improve understanding of reflux patterns specific to the Indian population. Participants will be healthy adults aged 18 and above, without gastrointestinal symptoms or major systemic diseases. The study will be conducted as a single-centre, 24-hour monitoring protocol.
