I am absolutely chuffed to bits, was diagnosed T2 in January. Have been eating low carb, essentially Keto since then. Received a free Freestyle Libre after following a link on here, today is day 1 with it. Assuming that it might not have totally settled but have just had readings of 4 and 4.4. My hba1c was 9.4 and fasting was 11.2 when I started. This low carb journey seems to be working!
 
Hi,

While I am absolutely delighted for you, and I know how hard you have been working at low carbing, so your numbers will definitely have been dropping, it is worth checking your Libre against a prick test a few times, to check that the sensor isn't running low.
Out of the 30 ish sensors I have run over the last few years, they usually read about 1-1.5mmol/l lower than my prick tests.
One sensor was between 2 and 3 mmol/l for its entire life, so I rang Abbott and they sent me a replacement.

So while I really don't want to dampen your delight, think how much more delightful it will be to check your readings against finger prick tests, and know that they are accurate.
 
Hi @Brunneria thanks for letting me know. Unfortunately due to a few reasons, I can’t use a finger prick monitor. Until this point I wasn’t testing at all due to it, so having the Libre is peace of mind. It’s good to have the knowledge that it might be out by about 1-2mol, so if it does rise significantly with anything I know to cut it out.

No worries. The numbers aren't everything! In your situation, I would pay more attention to the shape of the graph, the rises and falls, and the steepness. Also the indicator arrows. They are where (in my opinion, as a non-insulin user) the true value of the Libre lies.

So if you take the actual numbers with a pinch of salt, and instead monitor closely what the line does after food, you can still learn a tremendous amount about food, timing, how your digestion works, how stress and exercise affect you, and so on.

The Libre is an absolutely brilliant tool. :)
