    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.

    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!:)

    Thanks everyone! Keep the #'s coming as you get them (This poll is ongiing, set to not expire).

    So far it looks like the people who had the most A1C reduction are the ones who started with A1C's above 7.5. People with A1C's in the 6's seemed to stay about the same, but had fewer low's. Looking forward to seeing even more data and comments!

    Hailey's A1C went up a little but she was also having dramatic lows and severe highs. Her A1C appeared good but she was a mess. We are still striving to get back into the low 7's but puberty is making things extremely difficult. We have had a 9 :eek: since starting cgms but that was also during a really big growth spurt and we were without an endo for 2 of the 3 months, since we had not experienced such dramatic growth effect I was having difficulty without help :eek:

    We have not seen a low below 50 since starting the cgms :D

    I didn't respond to the poll, since we haven't had 3 months on the CGMS yet, but being on the CGMS for a month reduced our A1c from 6.8 to 6.5. I don't really expect it to go too much lower than that. We're dealing with a 4 year old who can't feel his lows or highs, and who is completely dependent on us to make adjustments. Also, I work part-time, so he's with caregivers who just aren't as...well, they're not as good at his control as I am. That's not a knock on them - I'm just around him more and have better instincts than they do.

    That is not to say that CGMS hasn't been very good for us. Our standard deviation is really, really good (most days in the 30s), and it has warned us of many lows that I doubt I would have caught otherwise. A1c is only part of the picture, for sure.

    Nicole,

    Don't you just hate those growth spurts. I end up struggling with numbers for a couple of days and then "hit hand on forehead" - must be growth spurt! Are you also in the mist of puberty????

    No kidding! She is prepubescent but the endo says it will be any day because she is cycling with her hormones :rolleyes: I swear, every time we get things right the very next day she either quits growing or starts hormonal things :rolleyes:

    Lots of testing, tweaking temp basals & carb ratios based on activity, and the trend info from my cgm. Plus, the consistent activity & workouts creating a "smoothing" effect even though I sometimes have to eat more to keep from dropping low.

    It's not something special, just lots and lots of practice in conjunction with data logging to see "what happens" and making adjustments in the future based on what I've seen.

    3 people have now reported A1C's in the 5% range using a CGMS...
