I wonder if any one can help me understand my self administered test. Background I was diagnosed with type 2 30 months ago wiht an hba1c of 64. I was offered metformin but chose the newcastle diet first. Blood glucose on first day was 13.5 it had dropped below 5.5 within 7 days. I lost 3 stone of which I subsequently regaind 1/2 so I am 2 1/2 stone lighter than when I started. Since then I have adopted a fairly low carb diet and for the last 30 months my hba1c's have been below 40. I was told I could come off the register but chose to stay on it as I wanted to keep testing and needed the strips. Knowing if I stopped testing I would go back to my bad old ways.
I normally work on 20-30g of a fast acting carb like bread or porridge to be my max at a sitting if I want to keep my 1 hour and 2 hour blood glucose < 7.6.
Out of curiosity I did a GTT using 75g of glucose using lucozade. I then tested my blood sugar at 1/2 hour intervals.
0 minutes - 4.8
30 minutes - 8.5
60 minutes - 12.5
90 minutes - 9.5
120 minutes - 4.1
It was pretty uncomfortable seeing my blood sugar going so high and I am confused what is going on. Clearly this is an abnormal response as it shouldn't have gone so high, but with the current criteria I would be considered non-diabetic as my glucose had returned (in fact overshot) my base rate by 2 hours.
My confusion is that for that to happen I obviously can produce enough insulin. Even at those high glucose levels I am able to shift the glucose out of the blood so I can't be massively insulin resistant anymore. Why in that case would the levels rise so high (even crossing the renal threshold) before the insulin kicks in. Is it possible that after years of beer drinking my pancreas expects a raised blood glucose to be followed by a glucose drop and therefore doesn't respond straight away. Or would that be considered pop-endocrinology !
