Current Type 2 Diabetes Mellitus treatments include life-style management, pharmaceuticals and may include bariatric surgery for the morbidly obese. However, issues with compliance, side effects and permanent anatomical alterations provide a need for an alternative therapy to modulate a peripheral nerve, such as the vagus nerve, in a manner that causes a plastic change in the glycemic regulatory system, with or without the involvement of the central nervous system (CNS), that changes the activity of an organ and thereby changing the activity of that organ. Low energy vagus nerve neuromodulation has potential as a new treatment for type 2 diabetes mellitus by inducing plasticity of the body's glycemic regulatory system with low energy transient stimulation. This will allow for effective use of a small implantable pulse generator that requires infrequent, or no, charging during the life of the device.
