Abstract
Introduction: Gastroesophageal reflux disease (GERD) is connected with body mass index (BMI) according to some recent studies. However, the link between overweight and severity of GERD symptoms is still unclear. Objectives: The aim of our study is to assess the influence of BMI on clinical presentation and occurrence of inflammatory changes in the esophagus in patients with GERD. Material and Methods: 121 clinically diagnosed GERD patients: 66 males (54.5%) and 55 females (45.5%), aged 19 – 89 years were involved in the study. After the detailed anamnesis BMI was counted and gastroscopy was performed. All individuals who agreed for upper endoscopy were divided into three groups. 42 patients (34.7%) were classified as Non-Erosive Reflux Disease (NERD), 53 patients (43.8%) were diagnosed with Erosive Esophagitis (EE), 11 patients (9.1%) with Barrett’s esophagus (BE). Among EE group 34 patients were diagnosed with grade A of esophagitis according to Los Angeles scale, 17 with grade B, 2 with grade C and none with grade D. The differences between groups were assessed using statistical analysis. Results: The mean age of patients was 50.2±12.9 years and the mean BMI was 25.5±4.2 kg/m2. Patients with BE were older (61.2±12.0 years) than NERD (48.5±13.6 years); (p=0.028) and EE (50.4±11.4 years); (p=0.008). BE had higher BMI (27.0±4.4 kg/m2) as compared to NERD (24.0±3.3 kg/m2); (p=0.022) and EE (24.4±3.1 kg/m2); (p=0.048). Hiatal hernia was more frequent in EE and BE (79.2% and 90.9%, respectively) as compared to NERD (45.2%); (p<0.001). Patients EE and BE more frequently complained to heartburn (84.9% and 72.7%, respectively) than patients with no mucosal injury (42.9%); (p<0.001). Sleeping problems were encountered by patients with higher levels of BMI. Conclusion: This study demonstrates that overweight predispose to esophageal inflammation and increase the frequency of heartburn and sleep problems in GERD patients.
