Re: [IPk] Re: High bgs 2 hours after meal

Hello Anna,

Just one comment about your low basal rate and high insulin sensitivity:
Unlike with long lasting insulin injected traditional way, basal rate
supplied by the pump is non-continuous. Basal rate is basically high set
of small equally distributed "boluses". My paradigm 722 uses shots of 0.05
IU of insulin and I suppose it is similar with other pumps. So in your
case basal rate of 0.30 IU/hour is turned into 6 shots of 0.05 IU every 10
minutes (you should hear a click coming from your pump anytime this
happens). My analysis shows that these shots are sometimes too high making
fluctuation of interstitial glucose level with peaks +/- 1 mmol/l with
frequency of couple of minutes. This results into poor overall diabetes
control with measurable highs and lows and higher need of insulin.
To reduce this fluctuation, you may think about mixing your insulin with
injection solution (I am sorry this might not be the proper name in
English) in rate 1:1 or even higher. This is normally done in case of
small children. It requires a bit of calculation as your basal rate and
boluses must be set twice higher, but it is not that big price for the
results it brings. My overall insulin consumption dropped by 40% after I
started mixing it in rate 1:1. And I also realized that less strong
insulin is milder to the insertion site.
I am just in the middle of experiments and analyses, I expect to provide
better explanation with some graphs and advice on my page in around one
month time.

Best regards    Ivan
