The A1C Warning
Your Blood Sugar Is Sending Signals Long Before Diabetes Begins
You can feel perfectly healthy and still have blood sugar levels that are moving in the wrong direction.
That's what makes prediabetes worth discussing.
Many people discover an elevated A1C during routine blood work, without experiencing unusual thirst, frequent urination, or other symptoms commonly associated with diabetes.
The result may seem like just another number on a laboratory report. But it can reveal an opportunity to address metabolic health before type 2 diabetes develops.
As a Family Medicine and Integrative Medicine physician at Velez Family Health in Orlando, I believe understanding these early changes is an important part of preventive primary care.
And with Direct Primary Care (DPC), we have the opportunity to discuss what the results mean, identify individual risk factors, and monitor progress over time.
What Is Your A1C Actually Telling You?
Hemoglobin A1C measures the percentage of hemoglobin in your red blood cells that has glucose attached to it. It provides an estimate of your average blood sugar over approximately the past two to three months.
Unlike a single glucose reading, which reflects your blood sugar at one moment, A1C helps identify longer-term patterns.
For most nonpregnant adults, the commonly used diagnostic ranges are:
Below 5.7%: Normal range
5.7% to 6.4%: Prediabetes range
6.5% or higher: Diabetes range
A result in the diabetes range generally requires confirmation unless the clinical circumstances establish the diagnosis. Certain conditions can also affect A1C accuracy, so results must be interpreted in context.
Prediabetes means blood glucose levels are higher than normal but have not reached the threshold for diabetes.
It does not mean that developing diabetes is inevitable.
Why Does Prediabetes Develop Without Symptoms?
Prediabetes often involves insulin resistance, which occurs when the body's cells become less responsive to insulin.
Insulin helps glucose move from the bloodstream into cells, where it can be used for energy.
When cells respond less effectively, the body may need to produce more insulin to maintain normal blood sugar levels.
Over time, blood glucose can begin to rise.
Because these changes can happen gradually, many people remain unaware of them until routine testing identifies a problem. Family history, physical inactivity, excess body weight, certain medical conditions, and other factors may increase the likelihood of developing prediabetes.
This is why screening based on age and individual risk factors matters, even when someone feels well.
Can You Change the Direction of Your Blood Sugar?
For many patients, lifestyle changes can significantly reduce the risk of progressing from prediabetes to type 2 diabetes.
Regular physical activity helps the body use glucose more effectively. Balanced nutrition, adequate sleep, and weight management when appropriate can also support metabolic health.
Research from the Diabetes Prevention Program demonstrated that structured lifestyle interventions substantially reduced the incidence of type 2 diabetes among higher-risk adults.
But meaningful change doesn't necessarily begin with an extreme diet or an unrealistic exercise schedule.
It begins with understanding which factors are relevant to your health.
For one patient, the priority may be improving daily physical activity. For another, it may involve reviewing eating patterns, sleep habits, or weight-related risk factors.
Some higher-risk patients may also benefit from a discussion about medication.
The appropriate approach depends on the individual.
Where Direct Primary Care Makes a Difference
An elevated A1C shouldn't be treated as an isolated laboratory result.
It can be the beginning of an ongoing conversation about metabolic health.
At Velez Family Health, our Direct Primary Care model supports that conversation through longer appointments, direct physician communication, and follow-up care.
Instead of focusing only on whether a number is normal or abnormal, we can discuss what may be contributing to the result.
That may include reviewing family history, nutrition, physical activity, blood pressure, cholesterol, medications, and other relevant health factors.
Because DPC uses a monthly membership structure for included primary care services, patients can have appropriate follow-up conversations without a separate office visit copay for each included visit.
Laboratory testing may involve additional charges, and the frequency of testing depends on clinical needs.
DPC doesn't guarantee that prediabetes will resolve. It provides a structure for continued evaluation, education, and management.

How Often Should Your A1C Be Monitored?
People with prediabetes are generally advised to have their blood glucose status reassessed at least annually, although some may require more frequent evaluation.
Monitoring helps determine whether blood sugar levels are improving, remaining stable, or progressing.
It also provides an opportunity to review whether a management plan remains appropriate.
In primary care, I consider these follow-up conversations important because metabolic health involves more than one laboratory value.
Don't Wait for Diabetes to Start Paying Attention
An elevated A1C is not a reason to panic, but it is a reason to become informed.
Prediabetes can provide an opportunity to identify risk factors and make meaningful changes before type 2 diabetes develops.
At Velez Family Health, my goal is to help patients understand their results and make informed decisions through preventive care and ongoing medical guidance.
If you're in Orlando and looking for a primary care approach that emphasizes prevention, continuity, and direct physician access, I invite you to explore our DPC membership.
