Investigation evaluating the effect of coffee on gastro-esophageal reflux disease.
Many patients with gastro-esophageal reflux disease (GERD) report that drinking coffee
causes heartburn. The purpose of this study is to investigate the effects of coffee on
gastro-esophageal acid reflux, and its relation to esophageal motility parameters in
patients who are already scheduled to undergo 48 hour wireless pH testing as a result of
having symptoms suggestive of GERD. The specific aims are to evaluate the effects of coffee
on GERD during daily life and to elucidate the underlying pathogenic mechanism by which
coffee induces reflux.
- persons undergoing wireless pH testing for diagnosis and treatment of GERD
- those under the age of 18
- pregnant and lactating women
- those who do not meet the inclusion criteria
