Intragastric balloon is associated with the following risks:

  • Development of an ulcer in the stomach- usually due to irritation from the balloon.
  • Sometimes the balloon needs to be removed to treat this complication.
  • Pancreatitis- due to irritation from saline filled balloon rubbing the pancreas which is located directly behind the stomach.
  • Death- a rare complication.
  • Obstruction of the stomach- this usually requires removal of the balloon.
  • Deflation of balloons and migration of the device out of the stomach into the intestine- this complication may require surgery to remove the balloon.
  • Persistent nausea and vomiting beyond 5 days require balloon removal- this is not common but can happen.

This list includes the risks most common for patients but is not an exhaustive list.
