Risks

Pain and nausea affect about one-third of people soon after insertion of an intragastric balloon. However, these symptoms usually only last for a few days after balloon placement. These symptoms can usually be managed with oral medications at home.

Although rare, serious side effects may occur after intragastric balloon placement. Call your doctor immediately if nausea, vomiting and abdominal pain occur any time after surgery.

A potential risk includes balloon deflation. If the balloon deflates, there's also a risk that it could move through your digestive system. This can cause a blockage that may require an additional procedure or surgery to remove the device.

Other possible risks include overinflation, acute pancreatitis, ulcers or a hole (perforation) in the stomach wall, which might require surgery to fix.
