Flash should also be prescribed as an alternative if a child and their family present a clear preference for it, or it meets their needs better than CGM. But unlike Flash, some CGMs can ‘talk’ to an insulin pump, which is important if you want to use a closed loop system. You can get your sugar levels in your target range more often as you have more information about when you’re high and low.

What we’re doing to help everyone get the tech they need  

Pay Attention to Symbol: When you see this> symbol in the first 12 hours of using the Sensor, if your readings don't match how you feel, or if there's no number, rely on your blood glucose meter for treatment decisions. For better understand indication signs on the scanner, read the image carefully. Severe dehydration and significant water loss might lead to incorrect Sensor glucose readings. If you suspect dehydration, seek advice from your healthcare professional right away. Takeaway: Glucose readings are automatically displayed in the FreeStyle LibreLink app only when your smartphone and sensor are connected and in range. With a CGM and a flash glucose monitor (FreeStyle Libre2), you can also set an alarm to sound if your sugar levels go too low or too high.

If you’ve been self-funding your tech, what did you notice about your diabetes management before, during and after using the device? Why the upper arm: It is flat, so the sensor stays put. It has good blood flow, which helps with readings. And the skin is thin, so inserting the sensor is easier. Alva S. et al, Journal of Diabetes Science and Technology, (September 2020). http://doi.org/10.1177/1932296820958754 If you’re pregnant, live in England or Wales and have type 1 diabetes, you should be offered a CGM. A CGM should be offered rather than a flash glucose monitor as evidence shows CGM can be particularly beneficial during pregnancy, and flash should only be considered if you can’t use CGM or have a clear preference for it. You can use a Sensor for up to 14 Days and should not be removed for 14 days, then it automatically Stops. At this point, the reader will tell you it is time to replace your sensor. If Sensor Glucose Differs from Blood GlucoseYou cannot remove a sensor for a while – once it has come off you need to replace it with a new one. Sensor is water resistant in up to 1 metre (3 feet) of water for a maximum of 30 minutes. Do not immerse longer than 30 minutes. Not to be used above 10,000 feet.
