As it turns out, I don't have diabetes. The blood tests came back negative. Fortunately, working for the ambulance service, I was able to talk with a paramedic who explained what, in the raft of blood tests, I was looking at. Apparently it's now called HbA1c which I didn't have a clue about.
Of course, this does leave the question that if it isn't diabetes causing the cramps... then what is it. So the investigation continues. My heart, howerver, is a cause for concern with my pulse pressure down to about half what it should be... but that's another story.
36 mmol/mol [20.0 - 41.0] - Note normal HbA1c does not exclude diabetes of recent onset.
HbA1c is what’s known as glycated haemoglobin. This is something that’s made when the glucose (sugar) in your body sticks to your red blood cells. Your body can’t use the sugar properly, so more of it sticks to your blood cells and builds up in your blood. Red blood cells are active for around 2-3 months, which is why the reading is taken quarterly.
