Systems and methods for peripheral nervous stimulation for metabolic and endocrine function

Systems and methods are provided for neuro stimulation. In one implementation, a system is provided that includes a stimulator introduced into tissue at a target location and a central controller that communicates wirelessly with the stimulator. The stimulator includes a power system that receives wireless energy transmission, and an electrode system that transmits an electrical pulse for stimulating the target location. The central controller includes a power system that wirelessly delivers power to the stimulator, a communication system that wirelessly communicates with the stimulator, and a processing system that controls the power system and the communication system. The central controller may instruct the stimulator to transmit one or more electrical pulses to the target location to affect an endocrine function (e.g., affect the glucose level of a patient).
