Continuous glucose monitoring grew from short research recordings to wearable sensors that track glucose patterns all day and night.

Wearable sensors track glucose every few minutes so adults with type 2 diabetes can spot trends and adjust food, activity, and medication safely.

Safe daily use of CGM means wearing it most of the time, aiming for steady time in range, and acting on trends with your care team.

Sensors that track sugar in interstitial fluid send near-real-time glucose trends to your device so you can adjust daily diabetes decisions with more

One wearable sensor tracks glucose every few minutes and growing research shows how that stream of data can sharpen everyday diabetes decisions.

Continuous glucose sensors in people without diabetes show how meals and exercise affect daily sugar swings, but health gains remain uncertain.

Simple tape tricks keep your CGM sensor secure, comfortable, and irritation free for its full wear time.

The best CGM sensor sites are soft, low-bump areas such as the upper arm, abdomen, buttocks, or thigh that match your device’s labeling.

Medicare Part B can pay for therapeutic continuous glucose monitors when you have diabetes, meet coverage rules, and use an approved device.

Many TRICARE plans cover continuous glucose monitors when you meet medical criteria and use an approved supplier.
