What is CGM?
Continuous Glucose Monitoring, or CGM, is an innovative way to much more closely monitor your blood sugar. Instead of pricking your finger periodically throughout the day, a small sensor under your skin provides automatic readings every 5 minutes. With a glucose monitor, you would only need to test your blood sugar when calibrating the system (frequency varies by brand) so your fingers can be saved.
What are the benefits of CGM?
- Because it is giving so many readings every day, CGM can help you look for trends in your blood sugar. CGMs will also catch if you trend toward crashes in the middle of the night when you might not be testing.
- Most people do not enjoy pricking their fingers constantly. A CGM device only requires finger pricks for calibrating (this varies by device, but typically not more than once or twice a day).
