Implantable Gastric Stimulation

Implantable Gastric Stimulation (IGS) is a pacemaker like device, where the pacemaker electrical leads are attached by a surgeon to the surface of the stomach. It is unclear how the device works, but it is thought that the pacemaker changes the electrical activity of the Enteric nervous system in the stomach, leading it to relax and dilate. This then is interpreted in the brain as a feeling of satiety. This leads to weight loss.

It is being tested in America and shows great promise. However early evidence suggests that it cannot produce the same reduction in excess weight loss as Bariatric surgery such as Roux-en-Y or Laproscopic Adjustable Gastric Banding (Lap Band)

Medtronic which makes heart pacemakers, is developing this treatment.
