Because with the speed that the transit pushes food through my stomach the slowness of release and absorption can make my levels go really high. When nearer to chronic constipation they can rise really significantly... I don't know why the lead up to impaction can give much raised rates.
However, because I add in more fat now, that too is absorbed differently than carbs - and that too is significant to affecting my bolus times.. Ie when I have my brie at night I do bolus for the qty of it, but I do it over a one hour extended. It is only a small bolus of 0.2 or 0.3 over 1 hour but I need that cheese and the extended.
Everbody is different. My liver is due for an ultrasound and my sleen in next couple if weeks, so this may be impacting as to why.
However, the pump does take a full hour to deliver any hourly rate fully in to our bodies and my acting time is also one hour. So if you add those two times up.. Thats why I never adjust the one hour before.
If I was to do a test at 4 am and 6am for example. And my levels had gone up say from 6 to 7.0 by 6am. I assume that my levels are starting to rise from 4.01am onward. Unless I want to faff around the next night to do a 5am test then I will alter the 3am and 4am.because I do assume that my level has gradually risen over the period of 2 hours.
Most days I am between 5 and 7.0 with an odd blip sometimes. Even at levels of 5ish they will change probbly by about 0.5 at max in two hours.
I do not anally examine my levels anymore, I am totally relaxed, rarely even writing them down. I had a cgm and when 1st on pump I was too watchful. I don't actually get up to test at 4am and 6- lol!!
I also eat small amounts of food and saw much improved stability of levels from having more fat.
Why? I haven't got a clue, it just works for me.
