The dream for all overweight and obese people to lose weight without surgery or having to go under a strict diet may come true…soon. Researchers from the company EnteroMedics has come up with a new technology and device called the VBLOC, which is an implant which blocks the hunger signal from the stomach. This blocking of the signal from the vagus nerve(located in the stomach) to the brain modifies the ‘hunger signal’ making a person eat less resulting in weight loss.
The device, which is under the final testing phase by the U.S. Food and Drugs Administration, has induced an average of 29.1 % reduction in weight in human study subjects, that figure is near the 30 % average weight reduction that results with gastric bypass and binding (weight loss surgery techniques currently available) but with far fewer complications.
Nausea has been the only side effect noted so far and EnteroMedics, manufacturers of the device, plan to perfect the technology so that a future device to be released may be passed through the esophagus thus eliminating surgical complications associated with present weight loss surgeries techniques such as gastric bypass and binding.
The final phase of testing with involve 300 people to further evaluate the technology and device’s safety and effectiveness.
The doctors and researchers involved in the study have expressed hope that this device would help stem the growing numbers of overweight and obese people in the U.S. “It is safe, effective and reversible.” said Henry Buchwald at the University of Minnesota (involved with the study).
If the technology and device would be deemed safe by the FDA, this might ultimately replace all other weight loss surgery techniques and would be prescribed for people who do not respond well to conventional weight loss techniques.
