@static192 . As with most things diabetic this question is difficult to answer.
There are so many other aspects to consider. Novorapid isn't the only thing that will affect blood sugar over a period of time.
Type of food is a huge factor.
Exercise, even a 5 minute walk can impact on levels.
Mental challenges, even having a debate with someone can affect levels.
Injection sites play a large part.
In answer to your question and with the benefit of a cgm I can largely back up your findings.
Nothing seems to happen within the first 30 to 45 mins after injecting. As for the 5 hr mark, well that's slightly more difficult. A lot of things happen within the 5 hrs that could influence results, but I would be happy to say that novorapid has the ability to affect levels after 5 hrs.
As pointed out though, we are all different.
