The HbA1c blood test is one that most people with diabetes are familiar with, at least to some extent. It measures the proportion of haemoglobin in our blood that has bonded with glucose, and is regarded as an indicator of your average BG levels over the preceding 3 months. “What’s your HbA1c?” is a question …

But most of us only look at the latest figures. I showed my own latest data in yesterday’s “What’s normal?” post. In preparing for my latest endocrinologist …

Looking back at my own experience I can see an issue relevant to this. I should reiterate: HbA1c only indicates what your average BG was. It says nothing about how wild …
