Full Study Name

The Esophageal Motility and GERD Database (IRB no. 3949)


This purpose of this study is to determine whether patients with irritable bowel syndrome (IBS) will be more likely to have a lower sphincter resting pressure than those who do not on esophageal manometry (a test used to identify problems with the esophagus). Researchers have recently found an overlap between patients with gastroesophageal reflux disease (GERD), a condition known to include heartburn, and IBS. Data from this study will be used to look for risk factors for GERD and other motility disturbances of the esophagus. Participants will be asked to complete a questionnaire and provide a breath sample.
