Weight Loss Success With Repeat Intragastric Balloon Placement After Hyperinflation and Removal of the Index Balloon.

Intragastric balloons are an increasingly common endoscopic alternative to bariatric surgery for the treatment of obesity. Hyperinflation is a rare complication that presents as acute-onset epigastric pain, nausea, vomiting, early satiety, abdominal distention or bloating, and rapid weight loss. Hyperinflation requires prompt diagnosis and removal of the balloon to prevent complications including gastric outlet obstruction or gastric perforation. We present a case of intragastric balloon hyperinflation with removal of the index device, followed by replacement with a second balloon, resulting in continued weight loss without further adverse events.
