Q: What is CGM:
A: Continuous Glucose Monitoring or as its now commonly referred to (CGM) is a revolutionary technology enabling people with Diabetes, or those just interested in their glucose readings, to take measurements at regular intervals. Tracking Glucose 24 hours per day allows for tighter glucose control in those with Diabetes.
Q: What are the benefits of CGM
A: The benefits of CGM are widespread and vary by user. The key benefits of a CGM system are it allows the user to proactively manage his/her glucose levels, mitigate high and lows more effectively, and gives additional insight into the effect of meals on blood sugar. Additional benefits include better glucose control and management during exercise or illness. Overall the American Diabetes Association has acknowledged that tight glucose control, coupled with a healthy diet can lower complications and risks associated with Diabetes. Additionally, Studies have shown that some CGM systems may help reduce A1C levels[i] and risk for hypoglycemia, whether users inject insulin manually via pen or syringe, or use an insulin pump
Q: How does CGM Work:
A: Continuous Glucose Monitoring Systems track glucose levels throughout the day. This is done by using a tiny sensor which is worn just beneath the skin. The sensor is inserted using an automatic applicator. The Freestyle Libre Insertor is virtually pain free and allows the user to insert the senor in just seconds, painlessly under the skin. An adhesive patch helps secure the sensor to the skin so the senor remains in place during times of bathing or showering. Additional products will be available soon by TryCGM.com to help improve adhesion of the sensor during times of additional moisture, such as during exercise, bathing, or even summer days. The Freestyle Libre comes with a reusable transmitter but can also work with your Android or Iphone Smart phone for tracking blood sugar throughout the day. Both the transmitter and the app together with a simple touch to your sensor, provides instant real time blood sugar readings, along with an arrow indicating the direction your blood sugar reading is heading. Custom Alerts can be set to enable better glucose control and warnings.
Q: How long does the FreeStyle Libre Sensor Last?
A: The Libre Sensor can be worn for up to 14 days
Q: Why does the FreeStyle Libre 14 day system require a 1-hour warm-up period? Are any readings available?
A: The 1-hour warm-up period allows your body to acclimate to the Libre Sensor and no readings are available. After the initial 1 hour warm-up period, you can immediately start receiving accurate glucose readings up to 14 days.
