(Note from January 25, 2024: Since this list was first published, Freestyle Libre 3 is now available. This sensor is smaller than the Libre 2 and sends readings directly to your smartphone every minute, among other perks).

Continuous blood sugar monitors are expensive, but what kind of diet and exercise do they do?” It helps you understand what’s best for you.”

When choosing a continuous blood glucose monitor on this list, consider models that your doctor has previously recommended. We are also considering including models with CGMs that have long sensor life and are popular with diabetics.

“Continuous blood glucose monitors can more intensively monitor blood sugar levels in diabetic patients,” Fenichel said. “These are particularly suitable for patients who need to be checked multiple times a day or who want to get feedback more frequently throughout the day.”

Anyone can buy a regular blood glucose meter, but a CGM system requires a doctor's prescription. Although your doctor may recommend a continuous blood glucose monitoring device for reasons related to your personal health and lifestyle to track your blood sugar trends and stay on top of your insulin levels, all CGM devices Diabetes care plans specific to people may not work.

CGM devices can also provide you and your doctor with more information about your blood sugar levels than standard meters. For example, the device can warn you about low blood sugar levels if they drop too low. It's a feature that helps patients avoid hypoglycemia,” Fenichel said. “You can tell not only what your current blood sugar level is, but also whether it's rising or falling.”

Here are some factors to consider when purchasing a continuous blood glucose monitor.

  • scan frequency: Real-time CGM continuously scans your blood sugar levels, automatically sends the data to your phone or receiver, and sends you periodic alerts about your blood sugar levels. In contrast, intermittent scan CGMs require you to scan the CGM with your cell phone or receiver to see the data. Some CGMs measure blood sugar levels more frequently than others.
  • Connectivity: Consider whether you want to connect your CGM to your smartphone or to a receiver. If you use a mobile phone, be sure to check whether the app is easy to use or offers special features.
  • Test type: Consider where the CGM's sensor will be placed on your body, how it will be inserted, and how often it will need to be replaced.
  • Insurance coverage: Find out if the CGM you're interested in is covered by insurance and how much it will cost to maintain and replace parts over time.
