Prediabetes in Broward County is one of the most common conditions we find, and almost nobody comes in looking for it. It turns up in routine blood work, in patients who feel completely fine, and the first reaction is usually the same: I have no symptoms, so how can anything be wrong?
That is exactly the problem. Prediabetes means your blood sugar is higher than normal but not yet high enough to be called type 2 diabetes. It is a number on a lab report, not a feeling. The Centers for Disease Control estimates that more than one in three American adults has it, and that more than eight in ten of them do not know.
The reason it is worth knowing about is that this is the stage where the outcome is still genuinely open. Once type 2 diabetes is established, the work becomes management. At the prediabetes stage, the research on lifestyle change is some of the strongest evidence in preventive medicine. This guide covers the numbers, the test, and what the studies actually show. We run blood work on site in Tamarac and see adults of every age, not only seniors.
- Prediabetes is defined by a fasting blood sugar of 100 to 125 mg/dL, or an A1C of 5.7 to 6.4 percent.
- It usually causes no symptoms at all, which is why a blood test is the only reliable way to find it.
- More than one in three American adults has prediabetes and most of them do not know.
- In the landmark Diabetes Prevention Program trial, structured lifestyle change reduced progression to type 2 diabetes by 58 percent, and by 71 percent in participants over 60.
- The targets in that trial were modest: about 7 percent of body weight and 150 minutes of moderate activity a week.
- Prediabetes is not a diagnosis of failure and it is not a guarantee of diabetes. It is information, and it arrives while there is still room to act on it.
What prediabetes actually is
Your body turns most of what you eat into glucose, and insulin is the hormone that moves that glucose out of the bloodstream and into your cells. In prediabetes, that system starts working less efficiently. The pancreas is still producing insulin, sometimes more than usual, but the cells respond to it less well. Glucose backs up in the blood.
That state can sit quietly for years. It is not type 2 diabetes, and having it does not mean you will develop type 2 diabetes. It means the process that leads there has started and is currently measurable.
It also matters beyond blood sugar. Prediabetes tends to travel with high blood pressure, unhealthy cholesterol levels and extra weight around the middle, and that combination raises cardiovascular risk on its own. This is why a prediabetes result is worth a proper conversation rather than a note in a file. If blood pressure is part of your picture too, our guide to high blood pressure treatment in Broward County covers that side of it.
The numbers that define it
Prediabetes is defined by thresholds, and there are three common tests. Any one of them can identify it.
- Fasting plasma glucose. Normal is below 100 mg/dL. Prediabetes is 100 to 125 mg/dL. Diabetes is 126 mg/dL or above. This test requires not eating for at least eight hours beforehand.
- A1C, also called hemoglobin A1C. Normal is below 5.7 percent. Prediabetes is 5.7 to 6.4 percent. Diabetes is 6.5 percent or above. This one reflects your average blood sugar over roughly the last three months and does not require fasting.
- Oral glucose tolerance test. You drink a measured glucose solution and blood is checked two hours later. Normal is below 140 mg/dL. Prediabetes is 140 to 199 mg/dL. Diabetes is 200 mg/dL or above.
The A1C is the one most people end up with, because it does not require fasting and can be drawn at any time of day. A fasting glucose is often run alongside it as part of a standard metabolic panel.
A single result above a threshold is a reason to repeat the test, not a final answer. Illness, certain medications and some blood conditions can all shift these numbers, and a physician should interpret them against the rest of your health rather than in isolation.
Why there are almost no warning signs
This is the part patients find hardest to accept, so it is worth being direct. In most cases prediabetes produces no symptoms whatsoever. You cannot feel a fasting glucose of 112. There is no headache, no fatigue that is distinguishable from ordinary tiredness, and no pain.
There is one physical sign that occasionally appears and is worth knowing:
- Darkened, velvety patches of skin, usually on the back of the neck, in the armpits, on the elbows or knuckles. The medical name is acanthosis nigricans and it is associated with insulin resistance. It is often mistaken for dirt that will not wash off.
- Skin tags in the same areas sometimes appear alongside it.
Symptoms that people associate with diabetes, meaning increased thirst, frequent urination, blurred vision, unexplained weight loss and slow-healing cuts, generally belong to blood sugar that has already crossed into the diabetic range. Waiting for them is waiting too long. If you are noticing any of those, that is a reason to be seen soon rather than at your next routine visit.
Who should get tested in Broward County
Current guidance is to screen all adults starting at age 35, and earlier for anyone carrying risk factors. Several of those risk factors are common across our patient population here in Broward.
- Being 35 or older, and rising steadily with age from there.
- Carrying extra weight, particularly around the waist.
- A parent or sibling with type 2 diabetes.
- Being physically inactive, meaning less than three sessions of activity a week.
- A history of gestational diabetes, or having given birth to a baby over nine pounds.
- Polycystic ovary syndrome.
- High blood pressure, low HDL cholesterol or high triglycerides.
- Being of Hispanic or Latino, Black, Native American, Asian American or Pacific Islander background, all of which carry higher rates of type 2 diabetes.
That last point matters in this county specifically. Broward has a large Hispanic and Caribbean population, and rates of type 2 diabetes in these communities run meaningfully above the national average. If you have several of the factors above and have never had your blood sugar checked, that is worth correcting at your next visit rather than at some point in the future.
We draw blood on site and go through the results with you in plain language, in English or Spanish. Adults of every age welcome, and we accept most Medicare Advantage plans.
What the test involves
There is very little to it, which is the argument for just getting it done.
- If your physician wants a fasting glucose, you will be asked not to eat for at least eight hours. Water is fine. Most people book the appointment first thing in the morning and eat afterwards.
- An A1C needs no fasting and can be drawn at any hour.
- It is a standard blood draw, usually a couple of minutes.
- Our diagnostic and laboratory service is on site, so the draw happens in the same building as the visit.
- Results come back within a few days and are reviewed with you, not just filed.
- If you are on Medicare, diabetes screening is a covered preventive benefit for people with certain risk factors, and it is often bundled into the Annual Wellness Visit.
One thing we tell every patient: ask for the actual numbers, not just the word normal. There is a large practical difference between an A1C of 5.2 and an A1C of 5.6, and both get reported as normal. Knowing which one you are lets you see the direction of travel over a few years, which is far more useful than any single result.
What the research says actually works
This is the section that justifies the whole article, because prediabetes is unusual among medical findings in how strong the prevention evidence is.
The Diabetes Prevention Program was a large randomized trial in the United States that followed more than 3,000 adults with prediabetes. It compared a structured lifestyle change program against medication and against placebo. The lifestyle group reduced their progression to type 2 diabetes by 58 percent over about three years. In participants aged 60 and over, the reduction was 71 percent. Lifestyle change outperformed the medication arm.
The targets in that program were not extreme, which is the part worth repeating:
- About 7 percent of body weight. For someone at 200 pounds, that is roughly 14 pounds. Not a transformation, a meaningful shift.
- 150 minutes a week of moderate activity. Thirty minutes, five days a week. Brisk walking counts.
- Sustained over time rather than done intensely and abandoned. The follow-up studies found the benefit persisted for years afterwards.
Medicare covers a structured version of this called the Medicare Diabetes Prevention Program for beneficiaries who meet the eligibility criteria, and many commercial plans cover something similar. If you have a prediabetes result, it is worth asking whether you qualify.
We should be honest about what this evidence does and does not say. It shows that structured lifestyle change substantially reduces the risk of progressing to type 2 diabetes across a large population over several years. It does not promise any particular result for any particular person, and nothing in this article is a substitute for an individual assessment with a physician who knows your history.
Practical changes that hold up
Advice that requires a different life than the one you have is advice that gets abandoned in three weeks. These are the changes that patients here tend to keep.
Change the shape of the plate before you change the ingredients
Half the plate non-starchy vegetables, a quarter protein, a quarter starch. You do not have to give up rice, bread, pasta or plantain. You have to stop letting them occupy most of the plate. For families cooking Caribbean and Latin food, this is the single change that fits without rewriting the menu.
Deal with liquid sugar first
Sugary drinks raise blood sugar faster than almost anything else and they do not make you feel full, so the calories are effectively invisible. Soda, sweetened coffee, juice and the sweeter cafecitos are the highest-return place to start.
Walk after meals, not just in general
A ten to fifteen minute walk after eating blunts the blood sugar spike from that meal. Three short walks after meals are easier to sustain in South Florida heat than one long session, and they add up to the same weekly total. If joint pain or balance is in the way, our therapeutic massage and physical therapy team can work on that first.
Sleep and stress are not soft factors
Short sleep and sustained stress both raise blood sugar through hormonal pathways. Patients often treat these as unrelated to a metabolic problem. They are not.
Track something, but only one thing
Whether it is steps, a weekly weigh-in or a simple record of what you ate, one measure you actually keep beats an elaborate system you drop by February. Our guide to healthy eating for older adults goes further into the food side of this.

Frequently Asked Questions
What blood sugar level counts as prediabetes?
A fasting blood glucose of 100 to 125 mg/dL, or an A1C between 5.7 and 6.4 percent, or a two hour oral glucose tolerance result of 140 to 199 mg/dL. Any one of the three is enough to identify it. Below those ranges is considered normal, and above them is in the range used to diagnose type 2 diabetes.
Does prediabetes have symptoms?
Usually none at all, which is the main reason most people who have it do not know. The one physical sign that sometimes appears is darkened, velvety skin on the back of the neck or in the armpits, called acanthosis nigricans. Thirst, frequent urination and blurred vision generally indicate blood sugar that has already moved into the diabetic range.
Can prediabetes be reversed?
Blood sugar can and often does return to the normal range with sustained lifestyle change, and the evidence for this is unusually strong. In the Diabetes Prevention Program trial, structured lifestyle change cut progression to type 2 diabetes by 58 percent overall and 71 percent in adults over 60. What that research supports is a substantial reduction in risk across a population. It cannot promise a specific result for a specific person, which is why individual follow-up with your physician matters.
How often should I be retested?
If a test comes back in the prediabetes range, retesting once a year is typical, though your physician may want it sooner depending on the rest of your health. If your results are normal but you carry risk factors, every one to three years is the usual guidance. The trend across several years tells you more than any single number.
Do I have to fast for the blood test?
For a fasting glucose, yes, generally at least eight hours with water allowed. For an A1C, no. The A1C reflects your average blood sugar over about three months and can be drawn at any time of day, which is one reason it is used so often. Your physician will tell you which test they want before you come in.
Is diabetes screening covered by Medicare?
Medicare covers diabetes screening tests for beneficiaries who have certain risk factors such as high blood pressure, a history of abnormal cholesterol, obesity or a history of high blood sugar, and screening is frequently included as part of the Annual Wellness Visit. Coverage details vary by plan, so call us with your plan name at (954) 417-4499 and we will check before your appointment.
