Prevalence and determinants of frequent gastroesophageal reflux symptoms in the Australian community

SUMMARY Frequent gastroesophageal reflux (GER) causes chronic inflammation and damages esophageal mucosa, which can lead to Barrett's esophagus. It has also been consistently found to be a strong risk factor for esophageal adenocarcinoma.
