When we are full, our stomach signals the Vagus nerve to tell our brain that we should stop. So they decided to create an implantable pacemaker device which stimulates the nerve and makes you feel full.
In the studies, the device did not reach its goal of more than a 10% loss of weight versus control patients. This is not very good, considering it does involve surgery. However the FDA approved it because of the possibility of long term weight loss.
Side effects included nausea and vomiting. Long term studies are underway.
I am not optimistic about this new device.
