Can you have the Orbera balloon if you've had an illostomy due to Crohn's disease?

Hi,
Unfortunately, Crohn's disease is a contraindication to Orbera (or other intragastric balloons, including Obalon). So we would not recommend this for you. Good luck with your weight loss.

Any inflammatory disease of the GI tract, including Crohn's disease, is considered a contraindication for placement of an intragastric balloon.

I'm sorry to say that based in the device specifications, Crohn's and any other inflammatory bowel disease constitutes a contraindication to Orbera placement.  So in this case it would be a no-go.  If obesity has been a long-standing problem, a sleeve gastrectomy may be your only surgical option, though it would come with added risks due to your prior surgeries and the chance of future Crohn's flares.
