Prediabetes: What It Is, Why It Matters, and How to Stop It Before It Starts
One in three American adults has prediabetes. If you are looking for guidance on prediabetes in Orlando, knowing the signs early can genuinely change your health trajectory, and more than 80% of people who have it don’t even realize it.
That’s not a statistic I share to alarm you. I share it because prediabetes is one of the few conditions where catching it early can genuinely change the trajectory, and it’s something I’ve spent a significant part of my career helping patients manage and reverse.
Understanding Prediabetes
Prediabetes means your blood sugar is higher than normal, but not yet high enough to be classified as Type 2 diabetes. Specifically, a fasting blood sugar between 100–125 mg/dL, or an A1C between 5.7%–6.4%, indicates prediabetes.
Without intervention, prediabetes typically progresses to Type 2 diabetes within 5 years. With the right changes, often surprisingly manageable ones, it can be reversed entirely.
What Causes Prediabetes?
Prediabetes develops when your body starts to resist the effects of insulin, the hormone that helps your cells absorb glucose from the bloodstream. When insulin stops working as efficiently, glucose builds up in the blood instead.
Risk factors include:
- Excess weight, particularly around the midsection
- Physical inactivity
- Diet high in processed carbohydrates and sugar
- Family history of Type 2 diabetes
- Age 45 or older — though it’s increasingly common in younger adults
- History of gestational diabetes
- Polycystic ovary syndrome (PCOS)
Florida’s lifestyle patterns, more sedentary work, heat that discourages outdoor activity, a food landscape heavy in fast food, make prediabetes particularly prevalent here.

What Are the Symptoms of Prediabetes?
Here’s the difficult part: prediabetes usually has no symptoms. That’s what makes regular lab work so important.
Some people notice subtle signs: increased thirst, more frequent urination, fatigue that doesn’t improve with rest, or darkened skin in body creases (a condition called acanthosis nigricans). But many people feel nothing at all.
The only reliable way to know is a blood test, which is part of routine annual labs at UCF Health.
Can Prediabetes Be Reversed?
Yes. This is the most important thing I want you to take away from this.
Research, including the landmark Diabetes Prevention Program study, found that lifestyle interventions reduced the risk of progressing from prediabetes to Type 2 diabetes by 58%. That’s better than the leading medication used for diabetes prevention.
To read the full breakdown of how the trial was conducted across 27 centers, review the randomized group data, and see the 10- and 15-year follow-up results, check out the NIDDK Diabetes Prevention Program (DPP) Overview.
What does that look like in practice?
- Modest weight loss — Even losing 5–7% of body weight makes a measurable difference
- 150 minutes of moderate exercise per week — That’s 30 minutes, five days a week. Walking counts.
- Dietary shifts — Reducing refined carbs and sugar, eating more fiber, prioritizing whole foods
- Sleep — Poor sleep directly impacts insulin sensitivity
- Stress management — Chronic stress raises cortisol, which raises blood sugar
At UCF Health, I work with patients to build realistic plans around their actual lives — not theoretical ones.

When to See a Provider
If you have any of the risk factors listed above, or if it’s been more than a year since you had bloodwork done, it’s time to come in. A simple fasting blood sugar test or A1C, both easily done at your annual visit, is all it takes to know where you stand.
If we catch prediabetes, we catch an opportunity. And in my experience, most patients who take it seriously make real, lasting changes.
Frequently Asked Questions
Prediabetes means blood sugar is elevated but hasn’t yet reached diabetic thresholds. With lifestyle changes, it can often be reversed. Type 2 diabetes is a diagnosed chronic condition, though it can also be managed, and sometimes sent into remission, with significant lifestyle intervention.
No. With appropriate lifestyle changes and medical support, many people with prediabetes never develop Type 2 diabetes.
Focus on high-fiber vegetables, lean proteins, whole grains, and healthy fats. Limit sugary beverages, white bread, white rice, and processed snacks. A registered dietitian can help you build a specific plan, UCF Health can provide referrals.
Sometimes. For patients at high risk of progression, metformin may be appropriate. This is a conversation I have with patients individually, based on their specific numbers and health history.
