You have made a range of remarks in this, so I've felt the need to break them down and respond.
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.
Yes, everyone is different. But you only feel that way because your body has adjusted to your levels being relatively high, that doesn’t mean that is normal. You may get false hypo symptoms from this as well as being ‘ok’ with highs.
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
I haven’t studied medicine, but by what you are saying for somebody to have knowledge of something medical related they must study medicine? People on this forum have much more knowledge than GP’s, but their knowledge doesn’t mean anything because they haven’t studied medicine? Medicine itself is much more than teaching about diabetes, living with the disease and having an obsession to make your life better, can’t be taught, I read a lot about diabetes as a passion. From what you are saying you seem to have studied it, but don’t seem to know the basics. I don’t believe that is the general consensus, and if you have read literature or papers showing evidence, please provide some links to enlighten me.
I also learn a lot form Dr Bernstein, who is one of the most renowned in diabetes management, and obtaining normalised glucose levels. Not mediocre standards, true non-diabetic levels. Dr Bernstein was met with comments exactly like this, having normalized his glucose levels to non-diabetic levels and reversing complications 'experts' thought were not possible, his experience and knowledge had no value as he didn't have the piece of paper to say he studied medicine. So at 45 years old he studied medicine ad started working in the field, did he change what he had been doing beforehand? No, he built upon it, so his knowledge was still there. He had a lot of pushback because his methods would cause financial loss to major firms.
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.
Post meal and after eating are exactly the same thing. Before eating would be pre-meal. Just as in post prandial glucose levels are levels after eating. Dr Bernstein has mentioned many times, when he sees patients with 200 md/dL at any point, even a couple of times per month he would treat them as early diabetics. 10-11 mmol/L after meals is not normal levels.
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.
They may want to get tested for early or pre-diabetes, if that’s the case often.
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).
Its good control, still not non-diabetic levels and I don’t achieve this by advocating mediocre control or believing 10-11 after meals is ‘normal’. To be able to better my diabetes management I have to know what the true non-diabetic levels are. There has been many studies which show the normal hba1c is around 83 mg/dL (~4.6mmol/L) and this is in adults with children slightly lower, and this is definitely not achieved by having ‘normal’ peaks after meals of 10-11. The J curve which has been shown by a number of studies (which I’m sure you are aware of, being a medical student) shows that the mortality rate increases both above and below the normal level of 83 mg/dL. If you are happy with your control or wish to manage your diabetes knowing the risks, then that’s your choice. But you can’t push stuff as being normal, when it is not. People need to understand what normal or true- nondiabetic numbers are to be able to strive towards it.
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
As above, please provide links to some of this literature. I don’t take what GP’s say as gospel, as the err on the side of caution. The reason the hba1c target is less than 7% is to ensure they don’t get sued for deaths by hypoglycaemia, not because they know that as ood control. Doctors have been pushing many things over the years as normal, which clearly have not been the case (prime example of high carb). Again 11 is not ‘normal’ levels for non-diabetics. I’m sure you have heard of Dr Bernstein being a medical student, but I suggest you read his book.
Sorry for the long post, but people can't achieve good/non-diabetic control if they want, without knowing what the true base conditions are. Dr Bernstein is a perfect advocate of this and his book is a must read, regardless of low carb or not.
