If insulin is active for 4-5 hours after a bolus, taken say at the same time/just before a meal, how can any T1 get to – and keep - a steady blood glucose level until 4-5 hours after the meal when the only insulin in the system is bolus insulin, balancing glucose from the liver. (Unless of course the glycaemic release from the meal matches the insulin active profile and everything keeps in step .... some hope!).
Yes, I know that insulin action peaks - for me it is around 2hrs after a bolus but it ACTS for a further two or three - and if the basal level is correct - in theory, it will bring BG levels down to their pre-meal level almost just in time for the next meal - five hours later.
What is a realistic expectation? Should us T1s expect a level of 6mmol/l or so a couple of hours after a meal? If so ... how does that work then?
Along the same lines - if I have my tea (evening meal) at say 8pm and go to bed at 11pm - what sort of level should I be aiming for at bedtime?
Hope all that makes sense - for information, my typical day is something like:
Breakfast 7am
Dinner 12:30pm (5.5hrs after breakfast)
Evening meal: any time from 6pm to 8pm (ish)
Bedtime: 10:30pm - sometimes get to stay up late though ... 11pm!!
