Can someone try the Orbera balloon if they've previously had a gastric bypass?

Prior gastric bypass is a contraindication for Orbera.  In other words, any type of gastric bypass or bariatric surgery is a reason why you cannot have Orbera or any other type of intragastric balloon.

Hi, great question. Unfortunately, if you've had any type of stomach surgery you cannot have an Orbera balloon (or other intragastric balloon, such as ReShape and Obalon). This includes gastric bypass, sleeve gastrectomy, lap band, or hiatal hernia repair (fundoplication). The reason is that your risk of stomach injury or perforation is increased if you have had prior surgery. This is an absolute contraindication.

Hello,
Orbera is contraindicated after gastric bypass. With gastric bypass the size of the stomach has be made smaller and placing a balloon would quite possibly completely obstruct anything that you would attempt to eat or drink.
I hope this helps,

Take care.
