Hi everyone,

Just wondered how much you consider a spike to be after eating? A rise of 2mmol? 5mmol? And what is the highest you would be happy with after 1 or 2 hours?
 
I asked the same thing previously and got a number of different answers ... I don't think there is any "right" answer and it depends on the tightness of your control. I try to go no higher than 8mmol at any time. Occasionally I will be in the 4s before eating and then in the 8s a couple of hours after - and a variation of +4 may not be ideal so I'm trying to get that down (and the Libre is helping) but I find, for me, the tighter the post-prandial level the higher my hypo risk is at 3-4 hours ....
 
Well I've had a nightmare with my libre. I had a 5g carb breakfast, took 1u novorapid and ended up 10.8 on my libre but only 7 on my meter... I was in love with my libre until today and now I'm annoyed with it!! I'm trying to stay below 8mmol also but I do have a range of 4mmol also. It's so difficult as I want try my best at this but it can be so frustrating! My morning spikes are the most difficult to control but I know if I have a good morning then the rest of the day is easier. Today has definitely been a very testing day!

3mmol max.
 
Would this be 1 or 2 hours after eating or after injecting? Thank you.
 
After eating, however I do nearly always bolus ahead of my food unless the meal is high in fat.
 
Even a non-diabetic will go up by 1.5 after eating, so don't be too strict with yourself!
 
Why don't doctors seem to be that concerned with post prandial spiking?

Maybe it's just my experience but my endo even told me I need not test after eating, only before each meal! He said that, from his experience, those with in-range levels before each meal and before bed will generally have an excellent A1C so other testing is "unnecessary"(!).

I've also read a lot of literature which talks about testing before meals but never about checking levels in the periods after eating.

I know that on this forum we all take a particularly proactive role in managing our T1D - do you think the general advice is given so as not to overwhelm people, or is it generally not as big a deal as we think so long as levels are back in range within a few hours?
 
My consultant also said that I shouldn't be testing after meals. However, I feel that I need to know what affect a meal will have and to check that I have had the correct amount of insulin. I cook each night so regularly have similar meals so I can look for patterns. Sometimes I find it a little overwhelming and frustrating but I know in the long run its going to be better for me.

If non diabetics go up by 1.5, how long does it take them to come back down? Is this a faster or slower process than diabetics with/without insulin on board?
 
In a normal person it seems to take 2-3 hours to return to normal levels, but there are not many studies performed on non-diabetics.
