Obalon is the FIRST and ONLY swallowable, FDA-approved stomach balloon system for weight loss. The Obalon Balloon System helps facilitate weight loss by taking up space in your stomach so you eat less. Three balloons are placed for a six-month non-surgical treatment, combined with a professionally supervised nutrition and exercise program for optimal weight loss. Patients in the clinical study lost twice as much weight as with diet and exercise alone. Stomach balloons can be an alternative to bariatric surgery.
