What your A1c number means

What is A1c?

The A1c blood test shows your average blood sugar over the past two to three months. You do not need to fast for it.

What the numbers mean

Below 5.7%: normal. 5.7% to 6.4%: prediabetes. 6.5% or higher: diabetes. Many adults with diabetes aim for an A1c below 7%, but your doctor will set the right goal for you.

Why South Asian families should pay attention

People of South Asian ancestry tend to develop type 2 diabetes at younger ages and at lower body weights, so earlier and regular testing is important.

How to lower your A1c

Losing 5 to 7% of your body weight, walking or exercising about 150 minutes a week, cutting back on sugary drinks and refined carbs, and sleeping well can all help. Some people also need medication.

How often to check

People with prediabetes usually check at least once a year. People with diabetes often check every 3 to 6 months, depending on how well controlled it is.
