BG profile for someone who eats breakfast, dinner and tea?

[Alzibiff]

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!!

Not an expert, but as far as I am aware, your blood sugar level will fluctuate after eating a meal....in much the same way as a non diabetic?

Don't know if you are on a pump, or are asking becasue you ar einterested in them. I have mine set, at teh moment, that my acceptable range is between 6 and 8 mmol/l. I know that this is too high, and I am in teh process of bringing this down, so that my ultimate aim is to be between 4 and 6 mmol/l. Now, do I always fall into the band..no. I have one of those pumps with a wizard, that advises you on what bolus insulin to take...you have to work out the basal rate yourself. There is a post meal setting, where it "allows your bg to raise by 2 units after a meal. This only has any effect if you test. So, say, it is 1 hour after lunch, and I test my blood, and my reading is 9 mmol/l..then, on current settings, this is OK...but if I test again another later, and I am still 9, the pump will advise me that I should take a bolus to bring my BG back into my desired range.

This doesn't look very good I know, and that is becasue of my settings!

Another thing to look at is the advice Drs give people who think that they may be diabetic. I can't remember exactly what the numbers are, but after a meal, their BG can get as high as (about!!!) 7, and this is still normal.I don't think that anyones bg, diabetic o not, stays within a small range of readings.

Sorry, not an expert, but hope that helped.
