Frequently Asked Questions
How do continuous glucose monitors work?
A continuous glucose monitor tests interstitial fluid. The FreeStyle Libre 2 sensor is FDA-approved for wear on your upper arm. The Dexcom G6 sensor is FDA-approved for wear on your abdomen, upper buttocks or upper arm. CGMs do not require finger sticks, but they do require you to have the receiver/reader or a smart device nearby. CGMs can automatically collect and share glucose data and can predict dangerous highs and lows before they happen to help you stay within your target range.
Who should use a CGM?
- People with type 1 diabetes taking insulin via injections or pumps
- People with type 2 diabetes taking insulin via injections or pumps and/or have frequent episodes of very low glucose
- People who have trouble recognizing the symptoms of low glucose (hypoglycemia unawareness)
