Implantable Gastric Stimulation

This procedure where a device similar to a heart pacemaker is implanted by a surgeon, with the electrical leads stimulating the external surface of the stomach, is being tested in the USA. The electrical stimulation is thought to modify the activity of the Enteric nervous system in the stomach, which is then interpreted by the brain as a sense of satiety, or fullness. Early evidence suggests that it is less effective than other forms of Bariatric Surgery.
