In today's society, as the number of obese people increases year by year, the incidence of gastroesophageal reflux disease (GERD) continues to rise. Although bariatric surgery has brought good news to these patients who are unable to lose weight on their own, it is still unclear whether it is effective in relieving GERD, or even inducing or aggravating GERD. In this article, we will review and provide evidence of the effect of bariatric surgery on GERD.

• Roux-en-Y gastric bypass surgery
• Internal gastric balloon surgery

Obesity and its comorbidities - including diabetes and obstructive sleep apnea - have taken a large and increasing toll on the United States and the rest of the world. The availability of commercial, clinical, and operative therapies for weight management have not been effective at a societal level. Endoscopic bariatric therapy is gaining acceptance as more effective than diet and lifestyle measures, and less invasive than bariatric surgery. Various endoscopic therapies are analogues of the restrictive or bypass components of bariatric surgery, utilizing gastric remodeling or intestinal anastomosis to achieve proven weight loss and metabolic benefits. Others, such as aspiration therapy, employ novel mechanisms of action. Intragastric balloons have recently been approved by the United States Food and Drug Administration, and a number of other technologies have completed large multicenter trials (such as AspireAssist aspiration therapy and Primary Obesity Surgery Endolumenal). Endoscopic sleeve gastroplasty and transoral outlet reduction for endoscopic revision of gastric bypass have proven safe and effective in a number of studies. As devices are approved for use, data will continue to accumulate for safety, effectiveness, and cost effectiveness. Bariatric endoscopists should be prepared to appropriately target and apply various endoscopic bariatric therapies in the context of a comprehensive long-term weight management program.
