HbA1c Blood Test
An HbA1c blood test is a test which looks at how much sugar your red blood cells have been exposed to in the last 3 months. It is useful as it tell you about your average sugar level rather than a finger prick test which just tells you what your sugar level is right there and then. The results are related but not directly e.g. an HbA1c of 48mmol/mol suggests an average sugar level of around 7.8mmol/L. HbA1c can be used to diagnose Pre-Diabetes or Diabetes as shown in the illustration. If you have no symptoms (e.g. thirst, weight loss) then two readings of 48 or above are needed to make a diagnosis of Type 2 Diabetes.
Lower Carbohydrate Diet
All carbohydrates are broken down into sugar and therefore by reducing the amount of carbohydrate in your diet you can reduce your sugar levels. Ultimately this can help prevent and treat Type 2 Diabetes in a lot of people.
