Blood sugar reading spiking after waking up
I just started using Freestlyle Libre 3. Both days so far had a reading in the 90s upon waking up just before getting out of bed. After getting up, showering and getting ready for work but no eating, the reading went up around 50 points both days. Is this a CGM issue or is something else going on? I have been type 2 for around 15 years but have been negligent about checking my glucose levels for about two years.
Hi
That is interesting, though probably very frustrating for you. Do you take any morning medicatons that might cause an increase in your blood sugar after waking? Do you still have your old glucose meter? If so, maybe you could double check with finger pricks to ensure the results are the same as those from your Libre 3, or at least close. I wish I could be of more help. Hopefully, others will chime in here. Best wishes. - Lori (Team Member) 
Hello
, My husband was going through this also. He was checking his blood sugar immediately upon waking. This was before eating or drinking anything. His healthcare team told him to test his blood sugar 2 hours after a meal, which is when his blood sugar returns to normal levels. Of course, we are all different. Have you been able to talk to your doctor? We would like to hear from you. Diane (Team Member)
