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

Incidence of serious events in the SMART trial (n=1/336)

of extensive research and testing, resulting in next-generation of weight loss balloons.  FDA approval was based on the most rigorous study design: double-blinded, randomized and sham-controlled.

patients have received the Obalon Balloon System worldwide.

Obalon bridges the gap between diet and exercise and surgery for patients with a body mass index (BMI) of 30 to 40 kg/m2

Swallowable: Non-surgical placement – The patient swallows a capsule with no anesthesia. Administration is discreet. It takes about 10 minutes with no down time for the patient.

Progressive Doses of Volume: Progressive weight loss – Adding balloons over time gradually increases the volume of occupied stomach space. Balloons are designed to help patients overcome weight loss plateaus and minimize side effects.

Floats: Feel fuller faster – Obalon balloons are gas-filled and float to the top of the stomach. Designed to reduce adverse symptoms and improve tolerability.

Pivotal Trial Highlights of 160 patients1

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 six months after the first balloon is placed.

The Obalon Balloon System is intended for adults with a body mass index (BMI) of 30 to 40 kg/m2 willing to follow a diet and exercise program. All Obalon balloons must be removed in 6 months. Patients with prior weight loss surgeries are not eligible. The most common side effects reported were mild abdominal pain and nausea which typically resolved within two weeks. You must take daily acid-blocking medicine prescribed by your doctor. For full Important Safety Information click on Safety Information and Patient Labeling.
