    Default Poll: A1C change after using CGM

    Please post ONLY if you have have used a CGM continuously for at least 3 months,
    and have A1C before and after the 3-month period!

    We are trying to gather results from CWD to see how it correlates to published studies such as
    Improved Glycemic Control in Patients with Type 1 Diabetes Using Real-Time CGMS

    Also please add a comment with your before/after A1C's, any any other info you'd like to share.

    I don't fit your criteria and didn't vote, but this is my history:
    Sept 2006- 16%
    Jan 2007- 6.5%
    May 2007- 6.3%
    August 2007- 6.3%
    December 2007- 6.4%
    March 2008- 7.0? When my doc reported the July A1c, he said the march one was 6.5, but in March he reported it to me as 7.0
    CGMS Start May 5, 2008
    late June 2008- 6.3%


    My blood sugar has not gotten much better on the CGMS and I doubt it makes much of a difference- it has muted a few highs, prevented a handful of lows, and given me a clearer picture of what happens during the night. That's all. When a sensor failed while I relied on it, my SG was 66 and my BG was 588, my highest ever reading.

    You seem to have excellent A1C's ever since you started controlling your BG after dx. Anything in particular that you do to achieve that, or would attribute that do? I can see in your case how the CGM would not have much opportunity to improve what you already have.

    Very little difference here. Her last A1C was 6.6 and she's been in the mid-6's for 2 years. The only thing the CGMS has really done is tightened up her standard deviation and drastically reduced the amount of lows she'd been having (to around 5% last time I checked). The projected low alarm has really saved us a few times and allowed us to make necessary changes.

    My A1c has been between 6.3 to 6.0 for the last 3 years while on my pump vs MDI (with MDI it varied from 6.2-7.1)... checked every 6 months. I'd have to go dig up my records to find the exact dates corresponding to the #'s. Last check was 6.1 in Feb.

    New check in 2 weeks... first since using my cgm regularly, so I'll let you know the result then.

    3/98 dx
    11/98 7.7
    5/99 7.3
    9/99 8.1
    2/00 8.4
    10/00 6.8
    6/01 8.9
    7/01 pump start
    10/01 7.0
    11/04 8.7
    6/05 6.9
    9/05 6.9
    1/07 7.7
    4/07 7.0
    8/07 7.2
    11/07 7.4-- started cgms and MM722
    2/08 8.3
    5/08 7.7
    8/08 7.6
    12/08 7.0
    3/09 7.6
    7/09 7.5
    10/09 7.1
    These are all I could come up with at the moment. If I found others, I'll add them.

    I couldn't vote since we haven't been on the cgms for 3 months yet. But I wanted to chime in saying that for us, it has already helped in dropping Christopher's a1c. He was 7.9 when we started and his last a1c test which was a couple of weeks ago was 7.4. This was after only 3 weeks on it!! I can't wait to see where we will be after 12 weeks!
