I wonder if that happened to anyone here: After making the 14 year old DS the March A1c (Q1), we got 8.1% up from 7.6% in Dec 2012. OK, BGs were not great for the period, so we start a different routine, like measuring BG every 3 hours, and if there's a high value or food intake, measure BG one hour after, and apply a correction if BG is over 120 or so. Doing like that and keeping careful record of BG, the average over the next 3 months (March-June, Q2) is 136 mg/dl, which corresponds to an A1c of 6.4%. On top of that 77% of Q2 BG measurements felt within the 70-170 range we've set as a target (although we also correct when is more than 120). So, the individual numbers cannot get any better. OK, let's be objective: perhaps numbers are not great, but I don't feel they're that bad. We go then to do the June's a1C (Q2), waiting very optimistic results and... 8.6%, even worst than Q1 that had even worst BG averages than Q2. 8.6% A1c would be an average of BG of 200 mg/dl for the last 3 months (I think). The only odd thing was that the week before the A1c BG was spiky, and we had to increase basals. But even though, this last week the values within range were 65% of the total, with a BG average of 152 (A1c of 6.9%), so it was not what I'd call an uncontrolled disaster. I'm puzzled. Of course, it's just numbers, but I'm surprised to see such a wide difference between the day to day BG measurements, and the quarterly A1c. The interesting thing is that previously, even with less measurements, we had A1c somewhere within 0.5% of the averages we kept. Did something like that ever happen to anyone? Care to share any thoughts? Is it the teen years?
