Benefits of Continuous Glucose Monitoring (CGM)

While home blood glucose meters provide valuable insights into your blood sugar levels at specific points in time, Continuous Glucose Monitoring (CGM) systems offer a more comprehensive view of your glucose levels throughout the day and night.

CGM systems use a small sensor inserted under the skin to continuously monitor glucose levels in the interstitial fluid. The sensor transmits data wirelessly to a receiver or smartphone app, providing real-time glucose readings, trends, and alerts.

Key Benefits of CGM:

Continuous Monitoring: Provides a constant stream of glucose data, allowing you to see how your blood sugar levels change in response to food, activity, and medication.
Trend Arrows: Shows the direction and speed of glucose changes, helping you anticipate and prevent high and low blood sugar levels.
Alerts: Warns you when your glucose levels are rising or falling too quickly, or when they reach pre-set high or low thresholds.
Improved Glucose Control: Studies have shown that CGM use can lead to better A1C levels and reduced risk of hypoglycemia.
Reduced Fingersticks: Minimizes the need for traditional fingerstick blood glucose testing.

However, CGM systems may not be suitable for everyone. They can be more expensive than traditional blood glucose meters, and require a learning curve to use and interpret the data effectively. Discuss with your healthcare provider whether a CGM system is right for you.

When to Consult Your Healthcare Provider

While home blood sugar testing empowers you to manage your health, it's crucial to know when to seek professional medical advice. Consult your healthcare provider if you experience any of the following:
