New Generation of Obalon

The older generations of Obalon were to be removed 3 months after the first balloon placement, but the new generation is designed to stay in the stomach for up to 6 months. The longer therapy cycle results in more weight loss and better success in maintaining it long term. It is worth noting that previous generations of Obalon were not FDA-approved and were available outside of the U.S., such as Mexico. The new generation is FDA-approved and is only available in the U.S.

How Does it Work?

Obalon BalloonA deflated capsule (size of a vitamin pill) is swallowed by mouth. Once the physician confirms that the capsule is safely in the stomach, it is inflated with gas, and the catheter is detached.

Unlike the traditional gastric balloon, there is no need for endoscopy and no need for sedation. However, the extraction of the balloon system needs to be done endoscopically. Each balloon has a volume of 250cc and the placement of each balloon takes about 10 minutes.

To help patients overcome weight loss plateaus, a second balloon and a third balloon are swallowed in 4 weeks and 12 weeks after the first one, respectively. As was mentioned earlier, the Obalon Generation 3 balloon system is left in the stomach for 6 months rather than 3 months. Since Obalon is gas-filled, the balloons are light and float to the top of the stomach with no pressure on the pancreas (as it is the case with liquid-filled balloons).
