An A1C of 6.8% falls in the diabetes range. The American Diabetes Association defines diabetes as an A1C of 6.5% or higher, so 6.8% is just above that threshold. That said, it’s not a crisis number. It sits close to where many treatment targets land, and with the right changes, many people bring it down within months.
Where 6.8% Falls on the A1C Scale
The A1C test measures your average blood sugar over the past two to three months. The American Diabetes Association breaks results into three categories:
- Normal: below 5.7%
- Prediabetes: 5.7% to 6.4%
- Diabetes: 6.5% or higher
At 6.8%, you’re 0.3 percentage points past the diabetes cutoff. For context, that translates to an estimated average blood sugar of roughly 148 mg/dL. Your doctor will typically want to confirm the result with a second A1C test or a different blood sugar test, such as a fasting glucose of 126 mg/dL or higher, before making a formal diagnosis.
What 6.8% Means for Your Health
An A1C of 6.8% does carry higher long-term risk compared to normal levels, but it’s a number that responds well to intervention. The complications people associate with diabetes, like nerve damage, kidney problems, and vision changes, develop gradually over years of elevated blood sugar. They become significantly more likely once A1C climbs above 7.2%, where research shows a measurable jump in both cardiovascular events and damage to small blood vessels.
At 6.8%, you’re below that higher-risk zone. The goal for most adults with diabetes is an A1C under 7.0%, so you’re only slightly above a common treatment target. Bringing your number down even half a percentage point puts you within that goal and meaningfully lowers your risk of complications over time.
The Target Isn’t the Same for Everyone
A 6.8% A1C doesn’t carry the same urgency for a 75-year-old as it does for a 35-year-old. The ADA recommends different goals depending on age, overall health, and how many other medical conditions someone is managing.
For otherwise healthy older adults, the recommended A1C target is below 7.0% to 7.5%. For older adults with multiple chronic conditions or cognitive challenges, the target relaxes to below 8.0%, because pushing blood sugar too low with medications can cause dangerous drops (hypoglycemia) that pose their own serious risks. In these cases, a 6.8% result would actually be considered well-controlled.
For younger, otherwise healthy adults, the standard target remains below 7.0%, and some clinicians aim for closer to 6.5% when it’s achievable without medication side effects. At 6.8%, you’re in a range where relatively modest changes can make a real difference.
What Typically Happens Next
If 6.8% is your first diabetes-range result, your doctor will likely confirm it with a repeat test. A single A1C can occasionally be skewed by conditions that affect red blood cells, such as iron deficiency or certain anemias. Once confirmed, the next steps depend on how far you are from your personal target and what’s driving your blood sugar up.
Many people with an A1C in the high 6s start with lifestyle changes alone. Losing 5% to 7% of your body weight, if you’re carrying extra weight, has a measurable effect on blood sugar. Regular physical activity, even 30 minutes of brisk walking most days, helps your body use insulin more efficiently. Reducing refined carbohydrates and added sugars in favor of whole grains, vegetables, and lean protein tends to lower A1C within two to three months.
Some people at 6.8% will also be prescribed medication, particularly if lifestyle changes haven’t moved the number on a follow-up test, or if other risk factors like high blood pressure or high cholesterol are also present. The treatment plan is based on the full picture of your health, not the A1C number alone.
How Often to Retest
Most people with a diabetes-range A1C get tested at least twice a year. If you’re actively making changes or adjusting medication, your doctor may recheck every three months to see whether things are moving in the right direction. Because A1C reflects a two-to-three-month average, testing more frequently than that doesn’t add useful information.
A 6.8% result is a signal to act, not a reason to panic. It’s early enough in the diabetes range that many people successfully lower their A1C to prediabetes or near-normal levels with sustained effort. The fact that you’re paying attention to the number already puts you in a better position than someone who ignores it.
