Charlotte's last a1c (5 months ago) was 7.8. It's usually in the 7s, and we've always been happy with that. Yesterday at her appointment her a1c came back at 6.3. I'm honestly having a hard time believing it! But so excited at the same time. We've done a lot of basal testing and fine-tuned her pump settings in the last month, but I think the Dexcom has made the biggest difference. She still has random highs, but at least hours don't go by without us finding out about them and correcting. And her night numbers are significantly better. Before the Dex I preferred that her bg be in the upper 100s before I felt comfortable sleeping. (and if I'm totally honest, a low 200 was even better) Now, I'm fine letting her sleep in the lower 100s. I still get up to check her at least once in the night, but since I know I'll wake up to the alarm if she gets below 80, those low 100s don't scare me like they used to. I really don't feel like she has any more lows than she used to either. Anyway, just finally feeling good about this darn disease! And I'm LOVING her dexcom!
