Why Choose a Continuous Glucose Monitor?

People who have diabetes, especially those who need to constantly monitor their blood sugar levels, have been able to obtain thorough monitoring with the use of continuous glucose monitors.CGMs are very effective in cases where more feedback than current and/or insulin is necessary so that the patient can follow their glucose trends. Instead of simply measuring blood glucose, CGMs give the patients the possibility for more information as real-time hypoglycemia or fluctuation of blood glucose levels.

Factors to Consider When Choosing a CGM

When selecting a CGM, consider the following:

Scan Frequency: Real-time CGMs automatically transmit glucose data to your phone or receiver, while others require manual scanning.
Connectivity: Look for models that offer easy integration with smartphones or dedicated receivers.
Test Type: Consider how the sensor is inserted and placed on your body and the replacement frequency.
Insurance Coverage: Verify which CGM devices have insurance coverage and the costs associated with maintenance and replacement parts.
