What is Continuous Glucose Monitoring
Continuous Glucose Monitoring (CGM)
Continuous glucose monitoring (CGM) devices help you manage Type 1 or Type 2 diabetes with fewer fingerstick tests. A sensor just under your skin measures your glucose levels 24 hours a day. A transmitter sends results to a wearable device or cell phone
Fingerstick checks only measure blood glucose at one moment in time. It’s like reading one page of a book. Doing more fingerstick checks gives you more snapshots, which can offer clues to what’s happening with your blood sugar levels. It indicates TRENDS.
A Continuous Glucose Monitoring device can show you a bigger picture of how diabetes affects you. CGM measures glucose levels every few minutes. That data shows a more complete picture of how your blood sugar levels change over time. This information can help you and your provider better understand how things like food, activity, stress and illness impact your blood sugar levels.
Lead to more personalized care: CGM doesn’t give the whole story of all the ways diabetes affects you. It tells you when glucose goes up or down, not why. But your provider can download CGM data from your device and review it for patterns and trends. They can then personalize your care based on what they learn.
Alert you to highs and lows: Most CGM devices send an alert when your glucose levels rise or fall a certain amount. With this information, you can make changes quickly. You may be able to treat or prevent highs or lows before they turn into a big problem.
