Obalon Gastric Balloon

Obalon Fluoroscopic Balloon System

The FIRST and ONLY FDA-approved 6-month, swallowable, gas-filled weight loss balloon system.

How the Fluoroscopic Gastric Balloon Works

The Obalon Balloon System is a swallowable intragastrical balloon system indicated for temporary use to facilitate weight loss in adults with obesity (BMI of 30 – 40 kg/m2) who have failed to lose weight through diet and exercise. The System is intended to be used as an adjunct to a moderate intensity diet and behavior modification program. All balloons must be removed six months after the first balloon is placed.

The placement of each Obalon balloon typically takes less than 10 minutes and does not require sedation. In your physician’s office, you swallow a capsule containing a small balloon and then your physician inflates the balloon. In the clinical study after placement, most patients returned to normal activities with no downtime.

“One of the most remarkable findings in the clinical trial was that patients were able to keep their weight loss.”
