The Orbera balloon is a relatively new weight loss modality introduced in the United States. There are no large numbers comparable to traditional weight loss surgery to make predictions with a great degree of certainty. In our practice, 30-50 lbs of weight loss have become both reasonable and expected even though our best weigh loss so far has been 80 lbs. As with any weight loss procedure, outcomes significantly depend on the patient's commitment and drive.
Thanks for the question. The amount you lose with Orbera will depend on a few factors, including your starting weight, your motivation level, and how much you exercise. In the US Pivotal study of Orbera, patients lost an average of 10.2% of their total body weight, which was about 22 lbs. This was 3 times more weight loss than patients who only followed a diet and exercise program. These numbers are excellent, but we find that in the "real world" patients will lose more -- typically 20-50 lbs, sometimes even higher. We provide a comprehensive 12-month program, with monthly dietician visits, to ensure that you are getting the maximal results and that they are sustainable.
