An A1C of 6.8% falls just above the diabetes threshold of 6.5%, but it’s below the 7% target that the American Diabetes Association sets for most adults with diabetes. Whether 6.8 is “good” depends entirely on your starting point. If you were recently diagnosed and your A1C was 9% or 10%, reaching 6.8% is a significant achievement. If this is the first time your A1C has crossed into diabetes territory, it signals that your blood sugar management needs attention.
What 6.8% Means in Everyday Terms
Your A1C reflects your average blood sugar over roughly the past two to three months. Using the standard conversion formula, a 6.8% A1C translates to an estimated average blood glucose of about 148 mg/dL. For context, a fasting blood sugar under 100 mg/dL is considered normal, and someone without diabetes typically has an A1C below 5.7%. The prediabetes range sits between 5.7% and 6.4%, and anything at 6.5% or above meets the diagnostic criteria for type 2 diabetes.
So at 6.8%, your blood sugar is running higher than normal, but not dramatically so. You’re in the early diabetes range, which is actually where treatment has the most impact on preventing complications down the road.
How 6.8% Compares to Recommended Targets
The American Diabetes Association recommends an A1C below 7% for most non-pregnant adults with diabetes. At 6.8%, you’re meeting that goal with a small margin. This is the range where the risk of diabetes-related complications (damage to blood vessels, kidneys, nerves, and eyes) drops significantly compared to higher levels.
That said, “below 7%” is a general guideline, not a universal rule. Some people benefit from a tighter target, while others do better with a more relaxed one. Your ideal number depends on several factors, including how long you’ve had diabetes, what medications you’re taking, and your overall health.
When a Higher Target Makes Sense
For older adults or people with multiple chronic conditions, clinical guidelines shift the A1C goal upward. Diabetes Canada’s recommendations illustrate this clearly: functionally independent people aim for 7% or lower, while those who need daily assistance with activities have a target range of 7.1% to 8.0%. For people living with frailty or dementia, the target widens further to 7.1% to 8.5%.
The reasoning is straightforward. Pushing blood sugar lower requires more aggressive treatment, which increases the risk of hypoglycemia (blood sugar dropping too low). Hypoglycemia can cause dizziness, confusion, falls, and in severe cases, loss of consciousness. For someone who is frail or has limited life expectancy, the immediate danger of a low blood sugar episode can outweigh the long-term benefit of tighter control. Functional status and life expectancy, not age alone, determine where your target should be.
When a Lower Target Makes Sense
If you’re younger, recently diagnosed, and not taking medications that carry a risk of low blood sugar, your doctor may encourage you to push below 6.5% or even closer to the normal range. Early in the course of diabetes, tighter control offers the greatest protective benefit for your heart, kidneys, and eyes. The closer your A1C stays to normal, the lower your cumulative risk over decades.
Keeping Your A1C at 6.8% or Bringing It Lower
An A1C of 6.8% usually reflects a combination of lifestyle choices and, in many cases, medication. The three biggest levers you have are what you eat, how much you move, and whether you’re taking prescribed medications consistently.
On the dietary side, the changes that move the needle most are reducing refined carbohydrates (white bread, sugary drinks, pastries) and replacing them with fiber-rich foods, lean proteins, and healthy fats. You don’t need to eliminate carbs entirely. Spreading them evenly across meals and pairing them with protein or fat slows the blood sugar spike after eating.
Physical activity lowers blood sugar both immediately and over time. Your muscles pull glucose out of the bloodstream during exercise, and regular activity improves your body’s sensitivity to insulin for hours afterward. Even a 15-minute walk after meals can meaningfully reduce post-meal blood sugar spikes. Most guidelines recommend at least 150 minutes of moderate activity per week, which breaks down to about 30 minutes on most days.
If you’re on medication, consistency matters more than most people realize. Missing doses or taking them at irregular times creates blood sugar swings that show up in your A1C. If side effects are making it hard to stay on your medication, that’s a conversation worth having with your doctor rather than quietly skipping doses.
How Often to Recheck
The American Diabetes Association recommends testing your A1C every six months if you’re meeting your treatment goals, and every three months if your medications have recently changed or your last result wasn’t in your target range. At 6.8%, if your target is below 7%, you’re in goal, and twice-yearly testing is reasonable. If you and your doctor are actively trying to bring it lower, more frequent checks help you see whether changes are working.
Keep in mind that A1C is a trailing indicator. It reflects the past two to three months, so any change you make today won’t fully show up in your next test unless enough time has passed. If you start a new exercise routine or adjust your diet, give it at least three months before judging the results by your A1C.
What Can Affect A1C Accuracy
Certain conditions can make your A1C read higher or lower than your actual blood sugar average. Iron deficiency anemia, kidney disease, and some blood disorders can skew results. Pregnancy, recent blood loss, or blood transfusions also affect accuracy. If your A1C doesn’t match what you’re seeing on a home glucose monitor, or if you have any of these conditions, your doctor may use alternative tests like fructosamine or rely more heavily on daily glucose readings to guide treatment decisions.
