Analysis of glucose median, variability, and hypoglycemia risk for therapy guidance

A system for determining glycemic risk, the system comprising:

• a continuous glucose monitor comprising a sensor configured to collect glucose data in interstitial fluid of a user;
• and
• a display device in wireless communication with the continuous glucose monitor, wherein the display device comprises:
• an input at which the collected glucose data of the user is received;
• a display;
• a nonvolatile memory in which is stored a glucose data processing program configured to program a processor to analyze received glucose data and from the analysis, produce a display;
• the processor connected with the nonvolatile memory, the input, and the display, the processor being configured to access the memory to load and run in the processor the glucose data processing program, wherein the processor is programmed to:
• determine a central tendency value and a variability value from the collected glucose data for each of a plurality of time of day segments;
• assess a hypoglycemia risk for each of the plurality of time of day segments by a determination of which of a plurality of hypoglycemia risk zones the user's central tendency value and the user's variability value for a respective time of day segment of the plurality of time of day segments corresponds to, wherein the plurality of hypoglycemia risk zones comprises:
• a first hypoglycemia risk zone comprising a first plurality of central tendency values and variability values, the first hypoglycemia risk zone corresponding to a first level of hypoglycemia risk;
• a second hypoglycemia risk zone comprising a second plurality of central tendency values and variability values, the second hypoglycemia risk zone corresponding to a second level of hypoglycemia risk that is relatively greater than the first level of hypoglycemia risk;
• and
• a third hypoglycemia risk zone comprising a third plurality of central tendency values and variability values, the third hypoglycemia risk zone corresponding to a third level of hypoglycemia risk that is relatively greater than the first and second levels of hypoglycemia risk, and
• concurrently display a graph of the central tendency values for each of the plurality of time of day segments over a one day period and an indication of which of the plurality of time of day segments is assessed to have the third level of hypoglycemia risk on the display of the display device.
