"Artificial Pancreas" schemes usually use ultra-short-acting insulins which are even quicker acting than "regular human" insulin. There is virtually no immediate danger from high BGL (but medium to long term for sure!). High BGL over long time in Type-2 diabetes means there is actually too much insulin production for your own good, leading to high insulin resistance, leading to a situation where the cells aren't getting enough glucose at all. But this state takes some time to develop. Low BGL is the other way around: immediate danger, long term it's easier to buffer or control. Keep in mind those are generalizations. Don't take this as medical advice. Don't think I'm saying there is no need to react to high BGL.

The chemical composition of insulins like Novorapid (which my daughter uses) are slightly faster than regular human insulin, but not nearly enough to account for the aforementioned (up to) 30 minute lag.

  > The chemical composition of insulins like Novorapid (which my daughter uses) are slightly faster than regular human insulin Huh, thanks, I was not aware that novorapid is faster than endogenous insulin (most graphs show it much slower, albeit when taken subcutaneous). I switched from Novorapid to Fiasp because of how long Novo took to act, funnily enough. Also, moderate-fun fact: intramuscular injections, while a bit painful apparently, can release insulin much faster than subcutaneous. By much faster I mean Lantus/24hr insulin can make you hypo within an hour, as per what I read online on a particular post.

    I was told this by a GP who had Type 1 himself. I very occasionally do this with Novorapid into my shoulder muscle (one needs a longer than usual needle for this) to drop a high blood glucose fast, for example after a failed infusion site at night. It does feel weird, but it does work. (This is not medical advice! This is dangerous! Ask your doctor!)

Just as a heads-up, people with type 1 often bristle at people using their experiences with type 2 to talk about type 1. It’s incredibly common, but you should be aware (you actually might be!) that type 1 diabetes and type 2 diabetes are incredibly different diseases, having almost nothing to do with one another apart from that they’re related to blood glucose. Even insulin-dependent type 2 is a very different ballgame to type 1. I’m definitely not implying a ranking here or devaluing your experience with a serious chronic illness. Anyway, I’m thick skinned about this, so this isn’t really about me. I’m just trying to let you know that you could engender negative reactions by being unaware of this common “sore spot”. EDIT: Sorry, I see you’ve addressed this in a different comment, so you’re aware. All good, I’ll leave this up as general advice to others.
