Diagnosing somebody at 11.1 doesn't mean that, 11.2 or lower is normal, that's their threshold. If a non-diabetic had a random level of above even 9 I can near enough guarantee they would reassess the person for potential diabetes.
I do have type 1 diabetes, and if my levels spike more than 10 mmol/L at any time, that would make me concerned. I try and stay in range of 4-7 mmol 80% of the time with no peaks greater than 10 after any meal. At 10-11 I feel very groggy, that's almost 3 times the normal glucose levels. Post prandial levels have been shown to have significant impact on a1c levels.
post meal/after eating what's the difference?
Gp's information must be backed up by some evidence or study of some sort, none of which I have seen. I may be wrong, but I've not seen any such evidence.
Well everyone are different. I for once do not feel any different if my blood sugar are 10-14 mmor or 6-7 mmol. I have several times checked my blood sugar, thinking it were low or normal and seen numbers up to 14 mmol.
Getting blood sugar over 16 mmol however makes me feel ******, so everyone are different there.
When you say
«Gp's information must be backed up by some evidence or study of some sort, none of which I have seen.» I have to ask, have you ever study medicine? Most of the curriculum for this study, and litterature on the subject have a consensus that blood sugar up to 11.1 mmol after something with high GI (glycemic index) are normal even for non diabetics. There is plenty of evidence to back it up if you read the correct litterature or books
Post meal and after eating are very different. Post meal are before eating, and would most likely be much lower in non diabetics if they havn’t eaten in a while. After eating however, are when the blood sugar breaks down the glucose, causing a temporary raise, hitting the peak 30-60 min after eating. And it is this peak I mean can hit 10-11 mmol in non diabetics when ingesting something with high GI.
I thought that maybe this was information all diabtics got from their diabetic nurse or gp at diagnosis. But it might be different practice from different countries.
Also I’ve tested a lot of my friend who are non diabetic, and well blood sugar over 9 mmol are very common if tested at the correct time, after eating or drinking something with much carb.
But if you’re able to keep your blood sugar between 4-7 mmol 80% of the time, I have to say you’re doing a pretty good job. Because that is hard and much work when being a type 1 diabetic
And I think that might be the reason for you feeling bad with 10-11 mmol, because you’re used to stay pretty low (I mean low in diabetic terms).
Bottom line, all the litterature I’ve read, and from my GP my understanding were that blood sugar up to 11 are not uncommon for non diabetics. But I mean as a peak, it should of course go down, and be under 7.8 mmol after 2 hours, and less than 6 mmol at the 3 hours mark
