What an A1C of 5.7 Means, and What to Do About It

Getting bloodwork results can sometimes leave you with more questions than answers, especially when you see a number you don't recognize.

If your A1C result comes back at 5.7%, you might wonder whether it's something to worry about or what it means for your long-term health.

An A1C of 5.7% falls at the beginning of the prediabetes range. While it doesn't mean you have diabetes, it can be an early sign that your blood sugar levels are higher than normal.

The good news? Understanding your results gives you an opportunity to take action before more serious health concerns develop.

What Is an A1C Test?

The hemoglobin A1C test is a blood test that measures your average blood sugar levels over approximately the past two to three months.

Unlike a standard blood sugar test, which measures glucose at a specific moment, the A1C test provides a broader picture of how your body has been managing blood sugar over time.

Health care providers commonly use A1C testing to screen for prediabetes and diabetes and to monitor blood sugar management in people who have already been diagnosed.

Understanding Your A1C Results

According to the Centers for Disease Control and Prevention, A1C results generally fall into three categories:

• Below 5.7%:Normal range

• 5.7% to 6.4%:Prediabetes range

• 6.5% or higher:Diabetes range

An A1C of 5.7% is at the lower end of the prediabetes range. It doesn't mean diabetes is inevitable, but it is a reason to discuss your results with a health care provider.

A1C results may also be affected by certain medical conditions, including some types of anemia, so your provider may recommend additional testing to confirm what the number means for you.

What Does an A1C of 5.7 Mean for Your Health?

Prediabetes occurs when blood sugar levels are higher than normal but not high enough to meet the criteria for diabetes.

It often develops when the body's cells become less responsive to insulin, a hormone that helps move glucose from the bloodstream into cells for energy.

Over time, elevated blood sugar levels can increase the risk of developing Type 2 diabetes and cardiovascular disease.

One challenge with prediabetes is that it often develops without noticeable symptoms. Many people don't realize their blood sugar levels are elevated until they receive routine screening results.

That's why understanding your numbers matters, even when you feel healthy.

What Should You Do if Your A1C Is 5.7?

An A1C result in the prediabetes range is an opportunity to evaluate your health habits and develop a plan with your provider.

Here are five steps that may help.

1. Review Your Results With a Health Care Provider

Before making major changes, talk with your provider about what your A1C result means.

Your provider can review your medical history, assess other risk factors and determine whether additional bloodwork or follow-up testing is needed.

2. Make Small, Sustainable Nutrition Changes

You don't have to eliminate every carbohydrate or follow a restrictive diet to support healthier blood sugar levels.

Instead, focus on balanced meals that include vegetables, lean proteins, whole grains and fiber-rich foods.

Reducing sugary beverages and choosing less processed foods can also support blood sugar management.

3. Add More Movement to Your Routine

Regular physical activity helps your body use glucose more effectively and can improve insulin sensitivity.

For many adults, a useful goal is at least 150 minutes of moderate-intensity physical activity each week, such as brisk walking.

If you're not currently active, start with manageable changes and gradually build a routine that works for you.

4. Focus on Long-Term Weight Management

For people who have overweight or obesity, modest weight loss may help reduce the risk of developing Type 2 diabetes.

Research from the Diabetes Prevention Program found that a structured lifestyle intervention targeting approximately 7% weight loss and at least 150 minutes of weekly physical activity reduced diabetes incidence by 58% over about three years among high-risk participants.

However, weight loss isn't necessary or appropriate for everyone. Your provider can help determine which goals make sense for your health.

5. Create a Follow-Up Plan

One A1C result is only part of your overall health picture.

Your provider may recommend repeat testing, additional screenings or regular follow-up visits to monitor your blood sugar levels.

For people with prediabetes, A1C testing is generally recommended at least once a year, although some patients may need more frequent monitoring.

The important part is not simply knowing your number but understanding what to do with that information.

Can You Lower an A1C of 5.7?

Yes. Many people can improve their A1C levels through sustainable lifestyle changes.

Regular physical activity, balanced nutrition, adequate sleep and weight management when appropriate can all support healthier blood sugar regulation.

However, results vary depending on individual health factors, and changes may take time.

Rather than focusing on reaching a specific number as quickly as possible, work with your provider to develop a plan that supports long-term health.

When Should You Schedule a Follow-Up?

If your A1C is 5.7%, it's a good idea to discuss the result with your health care provider, even if you feel fine.

A follow-up may be particularly important if you have a family history of Type 2 diabetes, high blood pressure, a history of gestational diabetes or other risk factors.

Your provider can help determine whether additional testing, lifestyle counseling or ongoing monitoring is appropriate.

Know Your Numbers. Understand Your Next Steps.

An A1C of 5.7% isn't a diabetes diagnosis, but it is valuable information about your health.

The goal isn't to panic over one number. It's to understand what that number means and take steps that may help reduce future health risks.

At Elite Medical Ocala, we believe preventive care should go beyond receiving test results. Understanding your numbers, discussing your options and following through with an individualized plan are important parts of managing your long-term health.
