It is important for you to understand that the intragastric balloon is a tool to help reach weight loss and must be used in conjunction with a planned diet, exercise and a behavior modification program. The amount of weight you lose (and maintain) will depend on how closely you follow your diet and adopt long-term lifestyle changes. Average weight losses of approximately 16 kg (35 lbs) to 25 kg (55 lbs) have been reported with the Spatz balloon. There is a possibility that you will lose only a small amount of weight or lose no weight at all while using the balloon. Of course, your commitment to dietary and behavioral changes will determine your success. There is also a chance that unhealthy, uncontrolled weight loss will occur and create adverse health consequences. Be sure to speak with your physician about this.
