Deep brain stimulation (DBS), which involves the insertion of electrodes into the brain to send small electric charges to it and alter the dieter’s perception on fullness and even attitude to food altogether, can be used to tackle the obesity problem. A three-year trial is currently underway in the US, with two volunteers having already undergone the procedure. Should the surgery be approved by the US Government at the end of the trial period, Dr. Donald Whiting, a neurosurgeon at West Virginia University Hospital that has performed two such interventions, says, other countries will also consider allowing it to be performed on patients who have tried it all and failed to lose weight.
