I had a diabetic clinic yesterday my consultant Prof.B was not there so I saw a Dr.C instead.
Dr.C went through the routine things with me then got to my last blood test.
Unlike my usual consultant he was not at all happy with my HbA1c reading of 36 (5.4%). It had gone up by 2 points since the last reading 3 months ago which I wasn't pleased about but he wasn't pleased because he thought it was too low.
He then interrogated (I can't think of a more applicable word) me about my blood sugar control.
I could see where the lecture was going so I told him I aim to keep my BS between 5-6 rather than the 4-5 I actually aim for. Dr.C was not happy with this and told me to relax my control and aim for between 6-9 - he went on about the dangers of hypo unawareness and driving under 5 (which I don't do) and asked me if I kept a diary.
I had taken my Libre in to show Prof. B but as soon as Dr.C had started to go on about the dangers of low sugars I kept it snuggly in my pocket - there was no way I was going to show him screen after screen of graphs in the red - erroneous or not.
I told Dr.C that I didn't keep a diary anymore but used software to print out my historic sugar levels should I want to see them. Dr.C asked if I would bring in a print out at my next visit.
First thing I did when I got home was to dedicate one of my meters to only record readings that are above 5.5 - I don't really like being underhanded but I got the impression Dr.C would have no compunction about snitching to the DVLA.
So I agree with
@donnellysdogs - be careful who you show your Libre to especially if it's reading low.
