1. A physiological monitoring system, comprising:

  • an analyte sensor to generate signals corresponding to monitored analyte level in bodily fluid under a skin surface of a user;

    a motion detector to monitor an activity level of the user corresponding to a completed exercise activity by the user;

    a processor operatively coupled to the analyte sensor and the motion detector to determine a previously monitored variation in the analyte level monitored by the analyte sensor based on the monitored activity level of the user, to receive a user-determined bolus quantity, to enable a therapy device to deliver the user-determined bolus quantity, to determine that the determined previously monitored variation in the analyte level exceeds a predetermined threshold, and in response to the determined previously monitored variation in the analyte level exceeding the predetermined threshold, temporarily disable the therapy device from delivering the user-determined bolus quantity; and

    a user interface in signal communication with the processor to output a warning of an impending hypoglycemic condition based on the determined previously monitored variation in the analyte level based on the monitored activity level of the user, the user interface configured to output the warning by at least displaying a therapy information relating to the user-determined bolus quantity and a prompt to receive a user input to confirm that the user-determined bolus quantity should be delivered, the therapy information and the prompt to receive the user input being overlaid on a real-time depiction of the analyte level;

    wherein the processor is configured to, in response to the user input, re-enable the therapy device to deliver the user-determined bolus quantity.
