What is prediabetes?

Being diagnosed with prediabetes means that your blood glucose (sugar) levels are higher than normal, but not high enough to be diagnosed as diabetes. It also puts you at high risk for developing type 2 diabetes.

Prediabetes can sometimes be referred to as borderline diabetes or non-diabetic hyperglycaemia (NDH).

The diagnosis of prediabetes comes from your HbA1c which is a blood test that is used to measure your average levels of glucose in your blood over a 3-month period. The ranges for HbA1c levels are represented below:

It may come as a shock to be diagnosed with prediabetes but the good news is that you are able to take steps to stop it from developing into type 2 diabetes.

Symptoms of prediabetes

There aren’t any symptoms of prediabetes. If you develop symptoms that are associated with type 2 diabetes then it means that you have probably already developed it.

The most common symptoms of type 2 diabetes are:

  • Passing urine more often than usual, especially at night
  • Increased thirst
  • Extreme tiredness
  • Unexplained weight loss
  • Genital itching or regular episodes of thrush
  • Slow healing of cuts and wounds
  • Blurred vision

Not everyone that has type 2 diabetes will experience symptoms so it is important to know what to look out for.
