Summary

▪ Obesity is reaching pandemic proportions globally, with overweight or obesity affecting at least two‐thirds of Australian adults.
▪ Bariatric surgery is an effective weight loss strategy but is constrained by high resource requirements and low patient acceptance.
▪ Multiple endoscopic bariatric therapies have matured, with well established and favourable safety and efficacy profiles in multiple randomised controlled trials (RCTs), and are best used within a multidisciplinary setting as an adjuvant to lifestyle intervention.
▪ Three types of intragastric balloon are currently in use in Australia offering average total weight loss ranging from 10% to 18%, with others available internationally.
▪ Endoscopic sleeve gastroplasty produces average total weight loss of 15–20% with low rates of severe complications, with RCT data anticipated in December 2021.
▪ Bariatric and metabolic endoscopy is rapidly evolving, with many novel, promising therapies currently under investigation.
