• Resumen

  • Barrett’s esophagus is a premalignant condition portending increased risk of esophageal adenocarcinoma. Given the significant morbidity and mortality of esophageal adenocarcinoma, identification of risk factors for Barrett’s esophagus and esophageal adenocarcinoma is crucial. There are a plethora of studies investigating the relationship of obesity with these pathologies. Recent studies reveal that this relationship may specifically be with central adiposity. Increased cell turnover and eventual carcinogenesis is likely precipitated by increased intragastric pressure but also is affected by the complex interplay of increased insulin resistance in patients with increased fat tissue. Further studies are warranted to evaluate if weight loss can decrease progression of Barrett’s esophagus.
