title: [Obesity, symptoms of gastroesophageal reflux and endoscopic findings in a referral hospital].
abstract: OBJECTIVE
  To determine association between obesity, gastroesophageal reflux symptoms, hiatus hernia and erosive esophagitis.
  
  
  METHODS
  Consecutive patients who underwent upper endoscopies at our center were studied. Before endoscopy, through a direct interview all subjects were asked to complete the Carlsson-Dent questionnaire. Weight and height of all patients were determined. Body mass index was calculated. At endoscopy it was looked for the presence of hiatus hernia and erosive esofagitis. We excluded patients with some of the following conditions: Pregnancy, ascitis, esophageal varices, esophageal, gastric or duodenal stenosis, and patient who required an emergency or therapeutic endoscopy. We compared prevalence of symptomatic GERD, hiatus hernia and erosive esophagitis between normal weight patients, overweight and obese.
  
  
  RESULTS
  A total of 196 patients were included for analysis, 122 women and 74 men, mean age 52.5 years, 40.3% were overweight and 28.1% were obese. There were 124 patients (63.3%) with symptoms of GERD determined by the C-D Questionnaire obtained. Hiatus hernia was observed in 87 patients (44.4%), and erosive esophagitis in 69 patients (35.7%). Prevalence of GERD symptoms in obese or overweight patients were similar to those normal-weight patients (66.4% and 56.5% respectively, p = 0.20) OR 1.52 (IC 95%, 0.82-2.82). Among obese or overweight hiatus hernia was observed in 47% compared to 38.7% of those normal-weight (p = 0.28) OR 1.40 (IC 95%, 0.76-2.59). Prevalence of erosive esofagitis was also similar in both groups 37.3% and 32.3% respectively (p = 0.52) OR 1.25 (IC 95%, 0.66-2.36).
  
  
  CONCLUSIONS
  This study didn't show association between symptoms of GERD, hiatus hernia or erosive esofagitis and overweight or obesity.
