1. A method of diabetes management, comprising:

  • sensing glucose level from a glucose sensor and providing sensor glucose data representative of sensed glucose level;

    calculating an output control signal as a function of the sensor glucose data;

    delivering medication in response to a delivery control signal;

    monitoring the amount of medication delivered;

    modifying at least one of the sensor glucose data and the output control signal as a function of the monitored amount of medication delivered, wherein the sensor glucose data becomes modified sensor glucose data and the output control signal becomes a modified output control signal;

    performing at least one of;

    intercepting the output control signal and substituting the modified output control signal as the delivery control signal without reconfiguring the step of calculating the output control signal; and

    intercepting the sensor glucose data and substituting the modified sensor glucose data for calculation of the output control signal without reconfiguring the glucose sensor,wherein the delivery control signal is based on at least one of the modified sensor glucose data and the modified output control signal.
