What is OBALON?

The FIRST and ONLY swallowable, FDA-approved 3-balloon system for weight loss.

The Obalon Balloon System is a swallowable intragastric 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 6 months after the first balloon is placed.
