How often does dexcom check blood sugar?

A Dexcom CGM system tracks your glucose levels continuously throughout the day and night. Your glucose reading is sent to your smart device or receiver as frequently as every five minutes. Dexcom CGM systems then translate your readings into dynamic data so you’re better able to manage your diabetes treatment.

Is interstitial glucose lower than blood glucose?

In the human body, ISF glucose in the cells and in the brain is likely a more relevant physiological parameter than BG values. This would mean that the ISF glucose values are not of lower relevance than the BG values, but rather just the opposite.

Why is my dexcom reading low?

One explanation may be that something is pressing on your sensor which can affect your Dexcom G6 readings. Once the pressure is relieved, your Dexcom G6 readings should be closer to your blood glucose meter. Choose a sensor site location that won’t be bumped, pushed, or laid on while sleeping.

Why does dexcom keep asking to calibrate?
