Hi.

I'm so confused. When should I be testing my sugars after I've eaten to get the most accurate result. The way I've understood it is novorapid takes 4hours to finish working. So in my head I assumed keep meal times 4 hrly get an accurate result. Recently been on holiday and my sugars unfortunately were high no idea why. It was hot but I didn't really stop either. I was eating at between 7 and 8 pm going to bed at half 9 getting a high reading before bed and in the morning. If I wakeat 5 BG usually 10 go back to sleep re-test at 8 usually 13. Usually take my levemir at 9 am/pm.

I got told I wasn't carb counting properly but I am I just try to stick to the same thing to try and keep it as steady as I can. I get told different things depending on which specialist I see. I'm just so frustrated and struggling as feel like I'm currently fighting a loosing battle.
 
Novo rapid lasts up to 6 hours. No matter how long the duaration of action is in you, if it is 4 hours for you, that doesn't mean you have to eat every 4 hours. Meal times don't have an impact on the accuracy of test results. Whenever you test, the test will be as accurate as your blood sugar monitor.

To see whether the bolus is covering the meal you should test 2 hours after eating. Whenever you test, the test will be as accurate as your blood sugar monitor. The trick is to understand what the results are telling you: is it telling you you didn't carb count accurately, or that your I:C ratio is too low, or that you need to pre bolus; or that you have insufficient basal insulin?

Heat can cause an increased insulin requirement in some people.
 
What should your bg be after 2 hours as if it was 8 for instance then surely you would hypo. However if you've had a fatty meal then it takes longer to process so your bg could still go up. It's so confusing. I have been told so many different things that I'm just feeling a tad over whelmed and disappointed that due to not having good enough control my dn refused to give me the metre that helps you carb count and tells you how many units of insulin you need.
 
I don't know why you would think that if you were 8 2 hours after eating you would go hypo. Perhaps you have a surplus of basal insulin if you are having those kind of post meal drops. Personally, if I was 8 2 hours after eating that would be getting a correction, 8 is high, not hypo.

The target is to be 5-9 at least 90 minutes after eating.

Its because if novo rapid continues working on your BG for up to 4/5 hrs then surely if you were an 8 at 90 mins then the novo rapid would continue to work for up to a further 2 and a half hrs potentially.
 
Because novorapid doesn't work in an entirely linear action, it has a peak of action at about 1-2 hours, maybe 90minutes ish and then it just fades off. The duration of action varies depending on the person and circumstance so for example, if you bolus, eat and then exercise while you have insulin on board from the pre meal bolus then that might result in a hypo. But that would be an unusual circumstance.

You probably need to get more of a grasp on what the duration of action for novorapid is for you. You would need to understand that if you were to set up a bolus calculator.

OK thank you. I feel like I'm asking idiotic questions. Sorry. Thanks again for the advice. Xx
