A gastric band system including a functional electrical stimulation component is provided. Stimulation electrodes (22) on the gastric band (20) may be used to stimulate the vagal nerve and/or splanchnic nerve, which can inhibit the patient's appetite. The gastric band may have an inflatable member for adjusting a stoma size. The stimulation electrodes may be mounted on the inflatable member. The system may include a controller (24) including a pressure sensor for monitoring the hydraulic pressure within the inflatable inner member and for controlling the stimulation component.
