15.2. Being Aware of Your Glucose
Warning: ALWAYS be aware of your current CGM value, trust how your
body feels, and do not ignore symptoms of high and low glucose. Even
though insulin delivery adjusts automatically in Automated Mode with the
goal of bringing your glucose level to your dened Target Glucose, severe
hypoglycemia or hyperglycemia may still occur.
If your CGM values do not match your symptoms, ALWAYS check your
blood glucose using a BG meter, consider treatment and/or CGM sensor
calibration if necessary. ALWAYS switch to Manual Mode if you feel you are
receiving inaccurate CGM values.
• Erroneously high CGM values can cause excessive insulin delivery,
leading to severe hypoglycemia, seizure, loss of consciousness or death.
• Erroneously low CGM values can cause prolonged insulin suspension
leading to hyperglycemia, DKA, or death.
If you are having symptoms that are not consistent with your blood glucose
readings and you have followed all instructions described in this User Guide,
contact your healthcare provider.
When you routinely view your CGM values and/or check your glucose, you can
better identify when you need to make a treatment decision or troubleshoot an
issue. If you are not wearing a CGM, it is advisable to check your blood glucose at
least 4–6 times per day (when you wake up, before each meal, and before going to
bed).
Check your glucose:
• Whenever you feel nauseated or sick
• Before driving a car
• Whenever your glucose has been running unusually high or low
• If you suspect that your glucose is high or low
• Before, during, and aer exercise
• As directed by your healthcare provider
When using a CGM, if your CGM values are dierent than what you expect
based on how you feel, then check your blood glucose using a BG meter to verify
your CGM value’s accuracy. For example, if you feel shaky and sweaty, which
usually means your glucose is very low, but your CGM value shows as in your
acceptable range, you should conrm by checking with your BG meter.
If your blood gluon readings are veried too low or too high, consider treatment.
A sensor calibration may also be needed; consult your compatible Dexcom G6
System User Guide for more information.
