Well, 'not an awful lot of benefit of having and HbA1c of 37 compared to 50' he says.
The DCCT and EDIC trials which are the cornerstone of the NHS treatment strategy for diabetics say; 'keeping blood glucose levels as close to normal as possible slows the onset and progression of the eye, kidney, and nerve damage caused by diabetes. In fact, it demonstrated that any sustained lowering of blood glucose, also called blood sugar, helps, even if the person has a history of poor control.'
Normal in this context was an HbA1c of 6%.
Your current HbA1c in old money is 6.2% (an excellent result). Putting you in the top7% or thereabouts of Type 1 diabetics in terms of control in the UK.
Your old HbA1c is 8.1%.
Just looking at the big complication; cardiovascular disease this is what was found;
'the risk of any heart disease was reduced by 42 percent in people who had been in the intensive treatment group (i.e. HbA1c of 6%). Volunteers in the intensive treatment group also cut their risk of nonfatal heart attack, stroke, or death from cardiovascular causes by 57 percent.
Have a look at the other benefits across the array of complications that you get from having such excellent control:

So, whilst you consultant is being very 'kind and tolerant' of you and your 'American book' he's talking, with respect, nonsense.
The final point is that the DCCT and EDIC were both done with high carb diets and lots of insulin (carbs per day were about 240 in both limbs of the study). If we can get low HbA1c without lots of insulin it's win win surely?
When I first started low-carbing seriously I got an HbA1c of 5.8% - my GP said that is far too low please get that up. Like a fool I listened to him and have yet been able to return to those levels. I put that advice down as the worst and most damaging medical advice I have ever received.
Stick to your guns Charles - you can see the benefits don't be fobbed off by well meaning but intransient HCPs.
Also; well done on the dinner party!
