I have no hypo awareness, so don't notice when it's under 4. I do notice when it's high & it takes longer/ is much more difficult to fix.
On the DAFNE course I was told fix hypos immediately, but do not do correction doses for hypers in between meals.
So if I don't notice any immediate effects when it's under 4 & there is no solid evidence that being under 4 does any long term damage, but I do notice the hypers immediately and there is a tonne of solid evidence on the long term risks of running high, why must I fix one and ignore the other?
So my advice, if you are feeding back to HCPs is that they should maybe consider if their advice is logical and internally consistent...
