HbA1c 5.6 vs 5.7: What One Decimal Means for Your Blood Sugar
A 0.1 difference can change the label next to your blood sugar. An HbA1c of 5.6% may fall in the normal range, while 5.7% is often the point where prediabetes starts.
That tiny shift can leave you wondering: How can such a small change mean so much? Does it really mean your blood sugar has changed that much?
The answer is more useful than simply knowing your number. By the end, you’ll understand what HbA1c 5.6 vs 5.7 actually means, why the cutoff matters, and what you can do with that information.
HbA1c 5.6 vs 5.7: What Is the Difference?
HbA1c is a blood test that gives an estimate of your average blood sugar over the past 2–3 months. It is different from a blood sugar test that shows what your level is at one particular moment.
The commonly used HbA1c levels are:
-
Below 5.7%: Normal range
-
5.7%–6.4%: Prediabetes range
-
6.5% or above: Diabetes range
This is why an HbA1c of 5.6% and 5.7% can get different labels.
But the numbers themselves are extremely close. There is no sudden change in your health when you cross from 5.6% to 5.7%. The category changes because a line has been drawn at 5.7%.
Why Does 5.7% Count as Prediabetes?
Doctors need clear ranges to identify people who may have a higher risk of developing type 2 diabetes. The 5.7% cutoff helps do that.
It is important to understand what this cutoff does not mean.
It does not mean that your body is healthy at 5.6% and suddenly unhealthy at 5.7%. Research shows that diabetes risk increases along a continuous scale as HbA1c rises. There is no single point where that risk suddenly switches on.
Think of 5.7% as a line drawn on a road map, not the edge of a cliff.
Crossing the line changes the category doctors use. It does not mean your body has suddenly taken a dangerous turn.
The cutoff is a tool for early action, not a verdict on how healthy or unhealthy you are.
Prediabetes simply means that your blood sugar is higher than the normal range and that your future risk of type 2 diabetes is higher. It does not mean that you have diabetes or that you are certain to develop it.
Does Going From HbA1c 5.6% to 5.7% Mean Your Health Got Worse?
Not in the dramatic way the numbers may make it sound.
Your HbA1c can move up or down over time. A change of 0.1% does not mean that your health has suddenly changed overnight.
It is also worth remembering that HbA1c is an average. It does not show every rise and fall in your blood sugar. Your result can also be affected by normal variation and certain health conditions.
So, 5.6% does not mean you have zero risk. And 5.7% does not mean you have diabetes.
Instead of focusing only on the label, look at the bigger picture: your eating habits, activity levels, weight, family history, and other health factors.
Is HbA1c 5.7% Something to Worry About?
HbA1c 5.7% is not diabetes. It is the lowest point in the prediabetes range and is better seen as a signal to pay attention rather than a reason to panic.
Your overall risk can depend on several things, including family history, weight, physical activity, diet, and blood pressure. Someone with an HbA1c of 5.7% and several risk factors may need more attention than someone with the same number but fewer risk factors.
This is where small, regular changes can matter. Eating a balanced diet, staying active, and maintaining a healthy weight can support healthy blood sugar levels.
What Can Affect Your HbA1c Result?
An HbA1c result is useful, but it is not always the complete picture.
Certain conditions can affect how accurate the number is. These include severe anemia, kidney or liver disease, some blood disorders, recent blood loss or blood transfusions, pregnancy, and certain medicines.
This is why an unexpected HbA1c result should not always be judged on its own.
If your HbA1c does not match your other blood sugar results or what your doctor expects, they may recommend another test to get a clearer picture.
What Should You Do If Your HbA1c Is 5.6% or 5.7%?
If your HbA1c is 5.6%, there is no need to panic about being close to 5.7%. Focus on maintaining healthy habits and continue regular health checks as advised by your doctor.
If it is 5.7%, don't treat the result like a diagnosis of diabetes. Instead, use it as an early warning to look at your lifestyle and other risk factors.
Small changes can add up. Being more active, making better food choices, and managing your weight, when needed, can help support healthy blood sugar and lower future diabetes risk.

Can HbA1c Go From 5.7% Back to 5.6%?
Yes, it can. Your HbA1c is not a permanent label.
With healthy lifestyle changes, some people can bring their average blood sugar down and move their HbA1c below the 5.7% cutoff.
But the goal should not be to obsess over whether the number says 5.6% or 5.7%.
The bigger goal is to maintain healthy blood sugar over time and reduce your risk of developing type 2 diabetes.
A 0.1% Difference Is Not a Health Verdict
An HbA1c of 5.6% and 5.7% are very close numbers. The difference in how they are classified comes from a clinical cutoff, not a sudden change in your body.
A 5.7% result means increased risk, not diabetes. And being below 5.7% does not mean you have zero risk.
The most useful response to a borderline HbA1c is not fear. It is awareness, regular monitoring, and early action.
