It seems you have read a little about 'Dawn Phenomenon' but have not seen that in many (including me) what happens is that the liver puts glucose into the blood stream in order to give us an energy boost so we could hunt/gather our breakfast. This was vital for people in the days before agriculture.
So a meal tends to stop it doing that, since if we have found food we no longer are in hunt/gather mode. Now if there is relatively little carbohydrate in that meal our blood glucose will either stay the same or go down as we produce insulin or use up energy. However if that meal is high in carbs then those will digest into glucose such that the overall Blood Glucose will spike up after the meal.
Those fasting readings are always the highest of the day
First HBA1c came back at 54. Fasting glucose was 7.5 Started low carbing in earnest, and testing at home. I realised that the fasting reading of the day was always my highest - I think its called the dawn phenomena.
The repeat of the HBA1c came back at 47 - just under the threshold for diagnosis - or so I thought. My fasting blood glucose was again raised down to the dawn phenomena.
Granted, I'm not entirely familiar with current diagnostic criteria in the UK, but a fasting glucose of 7.5 would be considered diabetic (not even pre-diabetic) by healthcare systems in many countries, regardless of your A1C. They would probably repeat the test to make sure, but other than that, a fasting glucose of 7.5 means your glucose metabolism is definitely impaired, even if you manage to keep your HbA1C low (which is of course very good and the goal).So it appears the GP has decided I am diabetic after all - even with an HBA1c under the cut off point and has put me on the diabetic register. To say I am shocked and upset at learning about the diagnosis this way is an understatement
