The Effect of the Intra-gastric Balloon on Gastric Emptying and the DeMeester Score.

Background And Aims: The mechanism of weight loss with the intra-gastric balloon (IGB) is thought to be a decrease in gastric emptying (GE); however the evidence is conflicting. Nausea, abdominal pain, and gastroesophageal reflux disease (GERD) can cause intolerance resulting in early removal. This is demoralizing for the patient and costly for the healthcare system.
