Viewing your glucose analytics:
Make sure to also monitor your glucose statistics under the analytics tab on the main dashboard. You can view both your glucose statistics and charts. You can view this for the current day you have selected in the calendar, or for a time range by adjusting the dates at the top.
Your stats will be green if they are great, yellow if they are just okay, and red if some improvement is needed.
- Average: The average of all the glucose readings in the selected date range. A lower average glucose is typically indicative of fewer glucose spikes. When enough data is gathered, this can calculate an estimated hemoglobin a1c value.
- Std Dev: Standard Deviation (SD) reflects the amount of variability in your CGM readings. The larger the SD, the more you stray from your glucose average. This provides insight into your degree of glucose “swings” and your level of insulin sensitivity, the lower the number the better. Important caveat: If you have major outliers, such as a one time value of 400, this will alter the SD and cause an artificially high value.
- Min: Your lowest glucose value within the selected date range.
- Max: Your highest glucose value within the selected date range.
- Spikes / Day: The number of glucose peaks, or “spikes” observed above 140 mg/dL. A few peaks are okay, but the goal is to see a gradual downward trend in this number over time.
- In Range: The percentage of time that glucose levels are within the pre-set “green” area (70-140) in your NutriSense app. The closer to 100%, the better. Important caveat: If you frequently have a fasting glucose < 70, this may alter your value. If you do not have any symptoms of hypoglycemia with this fasting value, then it is okay. You can adjust your upper and lower glucose thresholds under settings.
- Meal: Glucose value at the time the meal was logged. This should be your pre-meal value.
- Peak: Highest value after the meal. For optimal values, we want this <140 mg/dL.
- 2-hours: Glucose value 2-hours after the meal (post-prandial glucose).
- Delta: The total difference between the lowest and highest values during the 2-hour window after an activity or meal is logged. Lower delta values mean lower glycemic variability.
- AUC (Area Under the Curve): Area of the graph above the lowest point. There is no optimal value, but you can use this to compare your delta values from meal to meal. This is a good proxy for our insulin response and helps us see the overall effect of the meal. For example, one meal may spike the glucose for a short time, while another meal may raise it lower but for longer, their AUC could be equal.
The charts allow you to visualize your data as a graph. You can use the filter icon in the top right corner to hide or re-arrange charts.
