Based on a summary of currently available treatments, loss of about 7% to 15% of body weight is typical during the six months after intragastric balloon placement. Total excess weight loss ranges from 30% to 47%.
You can typically expect to lose between 20 and 50 pounds. The amount you lose depends on your starting weight and your ability to implement and maintain a new diet and exercise regimen. It is imperative to continue the new exercise regimen after the gastric balloon is removed, or you will regain the weight.
Our experience shows that a gastric balloon procedure typically results in a 2-3 stone weight loss over the first 6 months that the balloon is in place, although some have successfully lost as much more.
