Purpose: Gastroesophageal reflux disease is a common condition that is characterized with esophageal mucosal injury secondary to gastric acid reflux. The aim of this study is to reveal whether there is a relationship between binge eating disorder and gastroesophageal reflux disease. Methods: Patients with gastroesophageal reflux disease who underwent 24-h esophageal pH monitoring between 2016 and 2018 were evaluated retrospectively. Binge eating disorder diagnosis questionnaire was applied to 305 patients of these who agreed to participate in the study. The same questionnaire was applied to the control group consisting of the same number of healthy participants. A comparison was made between both groups in terms of demographic data and diagnosis of binge eating disorder. Also, 24-hour pH monitoring data of the patients diagnosed with binge eating disorder were compared with other reflux patients. Results: In the gastroesophageal reflux group, smoking incidence and higher body mass index was significantly more common. There was no significant difference between the two groups in terms of age and gender. Total reflux time, number of long reflux periods, longest reflux and DeMeester score were found to be significantly higher in patients with binge eating disorder.
