As I mention in the interview with Dan, the reason why the sleeve gastrectomy is so effective is that it changes the gastro intestinal hormones in the body. What we’ve discovered over time is that when a person loses a significant amount of weight those gastro intestinal hormones are working really hard to drive that person back to the weight they were.
With the sleeve gastrectomy, when we cut out part of the stomach, and leave that upper 2/3 in a tube shape, it changes those gastro intestinal hormones giving that person a new set point. That gives people a very powerful tool to help people change their eating habits. People really do need a tool when it comes to losing weight.
As I mention in the interview, surgery is only a tool to help a person change their eating habits long. And it becomes easier to change your eating habits and lose weight long term when you don’t have those gastro intestinal hormones working against you!
