1. An electrical dermal stimulation system configured to cause a delay in emptying of a patient'"'"'s stomach contents, comprising:

  • a housing having a base surface, wherein said base surface is defined by a total base surface area;

    a controller positioned within the housing;

    at least one electrode having a base surface and attached to the base surface of said housing, wherein the base surface of the at least one electrode is adapted to be in electrical contact with said patient'"'"'s epidermis and wherein at least one of the base surface of the at least one electrode and the base surface of the housing is adapted to be in physical contact with an epidermis of the patient; and

    a pulse generator positioned within the housing and in electrical communication with the controller and said at least one electrode, wherein the pulse generator is configured to generate a first plurality of stimulation sessions, wherein each of said first plurality of stimulation sessions comprises a plurality of electrical pulses and wherein each of said plurality of electrical pulses is defined by a first plurality of stimulation parameters, wherein said first plurality of stimulation parameters comprises a pulse width in a range of 10 μ

    sec to 10 msec, a pulse amplitude in a range of 100 μ

    A to 100 mA, and a pulse frequency in a range of 1 Hz and 100 Hz., said pulse width, pulse amplitude, and pulse frequency being defined such that, after applying at least one of said first plurality of stimulation sessions to the epidermis of the patient within 120 minutes of said patient consuming food, a post-prandial time to empty 50% of the patient'"'"'s stomach contents increases by at least 10% relative to a post-prandial time to empty 50% of the patient'"'"'s stomach contents without applying at least one of said plurality of stimulation sessions; and

    a plurality of programmatic instructions stored in a non-transient computer readable memory in a device physically separate from said housing wherein, when executed by said device, said programmatic instructions acquire patient status data, said patient status data including data indicative of the patient'"'"'s degree of appetite, determine a second plurality of stimulation parameters for a second plurality of stimulation sessions based on said patient'"'"'s degree of appetite and in response to an onset of an unplanned hunger event, and generate a signal based upon said determination, wherein said signal comprises data indicative of said second plurality of stimulation parameters and wherein, when executed, said plurality of programmatic instructions determine the second plurality of stimulation parameters for the second plurality of stimulation sessions based on a total duration of said first plurality of stimulation sessions and second plurality of stimulations sessions; and

    a transceiver positioned within the housing and in data communication with said device and at least one of said controller and pulse generator, wherein the transceiver is configured to receive said signal from the device and wherein the pulse generator is further configured to generate the second plurality of stimulation sessions in response to said signal.
