oops, by "pump data", I mean the pie charts in whichever Carelink reports have pie charts in them. I use those to look for concentrations of "off" numbers. It doesn't have to be way off but if I see an area where there's lots of lows, it's not unusual to have the next area turn out to have lots of highs. The pie charts kind of get the "trees" of individual readings out of the way and replace them with a "forest" of results that are more macro than micro. If you can find some areas with numbers that are off, look at pump settings there. If the fasting is off, I will tweak the basal, just a little bit, and if it's post-postprandial, I'll tweak the ratio. For this "theory", it doesn't matter if it's up or down, the point is to see what you can do and what happens when you make a change. If you want, it is probably recommended to check with your doctor or CDE, because insulin is wicked and all that but, if you propose changes in a careful manner like that, I would be very surprised were a doctor not to go along with the suggestion.
Another suggestion might be to get a fake identity and post a thread w/ specifics, since our responses are seem to be heavily weighted towards "support" which is a great display of love from the community but I wanted you to get some nuts and bolts with which to fix the problem.
Also, re Doris' comments, I haven't had an upsetting A1C since 2007, when I hit 7.7 when I started working out all of the time, still basically "carb guessing" since I had ignored any advances in diabetes theories that had come about since my DX in 1984. I love trying to propose solutions to diabetes puzzles and will keep at it for a while at least.
The other ***shocking*** thing about this thread is that no one has proposed the official Tu panacea that crops up in these threads of...LOW CARB!!! Hee hee. While I don't do that myself, I will admit that I do pretty light, regular eating during the week (work is near pretty yucky food choices, Wendy's, BWW, etc. Blech. There is one really brilliant upscale Mexican place that I *can't* go to because I will get back to 300 lbs in no time...). When I eat similarly/ identically, it may help make my use of the pie-charts more meaningful, since the inputs tend to be similar. These days, I'm putting more carbs in, trying to replace some booze with stuff like oatmeal. It's interesting but it seems like the results are a bit more varied than I'd like but it's also hard to say since the CGM has seemed to be a bit less accurate than usual.
