Ideas

Hey Neil, your correction should depend on your BG level and your sensitivity to the insulin, I mean for me 1unit brings my BG down by 4. I can see where novorapidboi is coming from though, there is no consistency with amounts of corrections, therefor I wouldn't want to comment on how to fix those high BG results. If in this position i would prob have tried adjustin BI b4 changing any ratios. Hope you've been able to gain a little control now :-)

In defence of fractional ratios!

My endocrinologist was most supportive of fractional ratios. It was his idea and I was skeptical but he convinced me to give it a try. As I lived on fairly regular meals I was able to achieve these for breakfast and lunch but often had problems with evening meals (more difficult to count carbs). You need a demipen and the ability to multiply in decimals. Or, you have the same things for breakfast everyday and calculate once.

It does smack of obsession but I found it fine.

I think fractional ratios are good too, provides you with more accurate carb counting and therefore better BGs, I personally dont require high levels of accuracy, I usually always round up my carbs anyway........

There is a lot of information to take in there but the first thing I noticed, which really needs to be addressed, is the consistency of your correction doses, sometime you take 3 for a 14, sometime 2, and that pattern continues throughout.

If your not consistent with these then you will never be able to pin point the real causes for highs and lows as it may be your correction that is responsible as opposed to your carb/insulin ratio......

On Monday 21st at 23:50 you corrected a 26.9 with 6 units, assuming the normal correction rules apply at this time, which is 1 unit drops 2.5 mmol/l then you would have dropped to 11.9, so not enough really. The reality is that the higher you are the more you need, or in other words, the less effective 1 unit of insulin is. If I was 26.9 I would of taken 21 units to bring me on target. Everyone will respond differently to 1 unit of insulin the higher the blood
glucose.

Have to disagree, my Dafne educators told me you should NEVER take more than 4 units as a corrective dose. If you take bigger & bigger doses of insulin, your body just "hides" it somewhere & it actually becomes less effective. In fact insulin is LESS effective at higher doses. I unit should reduce bs by about 3 mmol.

You should try and investigate this actually......................you may or may not be similar to me but these are the values I use.............

Blood Glucose: less than 10mmol/l - 1 unit drops 2.5mmol/l

Blood Glucose: between 10-13mmol/l - 1 unit drops 2mmol/l

Blood Glucose: between 13-17 - 1 unit drops 1.5mmol/l

Blood Glucose: above 17 - 1 unit drops 1mmol/l

My resistance may even go higher but thankfully I am seldomly much over 17. This is only what I have discovered and is not the opinion of any medical professional but I strongly believe this is the behavior of insulin as the blood glucose rises...

Sorry if I banged on a bit there........but I felt I couldn't comment confidently on your results knowing that the corrections were different from day to day and also my point regarding resistance.........

Hope this helped...................

I could agree that higher doses become less effective but you have to at least be open to the fact that higher blood sugars need more than 1 unit to drop you by 2.5......

For me personally, and others, the evidence is right in front of them. It was mentioned that 4 units should be the limit when at the stage of establishing basal doses and insulin/carb ratios.....in this case this rule is wise........

The handbook also states that at higher doses this rule,referring to the standard drop of 2.5, may not apply.....

The DAFNE educators are only limited to the cirriculum set out in front of them. With regards to my control my knowledge exceeds that of any of the DSNs I deal with........however there help is valuable and sometimes a fresh set of eyes is welcome......
