1. A glucose sensor system for monitoring glucose concentration in a biological sample of a host, the system comprising:

  • a continuous glucose sensor configured to produce sensor data indicative of a host'"'"'s glucose concentration, wherein the continuous glucose sensor comprises a sensing region and a sensing membrane located over the sensing region, and wherein at least a portion of the glucose sensor is configured for transcutaneous implantation; and

    an electronics module configured to receive sensor data from the continuous glucose sensor over a current time period, the electronics module comprising a processor configured to process continuous glucose sensor data based solely from the host over a past time period using a pattern recognition algorithm to recognize a time of day associated with a physiological pattern of the host'"'"'s glucose concentration over the past time period, and to detect an approaching clinical risk associated with the recognized pattern based on a comparison of the sensor data over the current time period with the recognized pattern,wherein the system is configured to present, on a display, a recommendation to aid the host in proactively avoiding the clinical risk associated with the recognized pattern.
