Prediabetes means your blood sugar is higher than normal and not yet high enough to be diagnosed as type 2 diabetes. It is the body’s early warning that the way it handles blood sugar is changing, and it raises the risk of developing type 2 diabetes, heart disease, and stroke. The encouraging part is that prediabetes can often be reversed, and acting early makes a real difference. Avita MD primary care providers diagnose and manage prediabetes for adults in Los Altos, Mountain View, and Los Gatos.
What are the symptoms of prediabetes?
Most people with prediabetes have no symptoms at all, which is why it so often goes unnoticed. Blood testing is the only reliable way to find it.
- Usually no symptoms, so testing is what catches it
- Darkened patches of skin on the neck, armpits, or groin
- Small skin growths in areas where skin folds
- Increased thirst or more frequent urination if blood sugar rises further
- Fatigue
Diagnostic ranges
| Test | Normal | Prediabetes | Diabetes |
|---|---|---|---|
| A1C | Below 5.7% | 5.7% to 6.4% | 6.5% or higher |
| Fasting blood glucose | 99 mg/dL or below | 100 to 125 mg/dL | 126 mg/dL or higher |
| Oral glucose tolerance | 139 mg/dL or below | 140 to 199 mg/dL | 200 mg/dL or higher |
How does Avita MD diagnose and treat prediabetes?
Diagnosis is straightforward and starts with a blood test, most often an A1C or a fasting blood glucose. Because Avita MD has on-site labs at every location, testing is convenient and your results come back without an extra trip. If your numbers fall in the prediabetes range, your provider explains what they mean and builds a plan with you.
Management centers on changes that work, including modest weight loss, regular physical activity, and a healthier eating plan, and your Avita MD provider tracks your A1C and weight over time so you can see progress. Same-day and next-day appointments make it easy to get started and stay on schedule. When weight is a major factor, your provider can connect care with the practice’s medical weight loss services, and when blood sugar keeps rising, medication may be added and specialty referrals coordinated to keep type 2 diabetes from developing.
When should you see a doctor about prediabetes?
See a primary care provider for a blood sugar check if you are overweight, are age 35 or older, have a family history of diabetes, had gestational diabetes, or have high blood pressure or high cholesterol, since prediabetes usually causes no symptoms and screening is the only way to find it. If you have already been told you have prediabetes, regular follow-up matters so your provider can track your numbers and adjust the plan. Seek prompt care if you develop increased thirst, frequent urination, blurred vision, or unexplained fatigue, since these can signal that blood sugar has risen into the diabetes range.

Prediabetes: Frequently Asked Questions
What is prediabetes?
Prediabetes means your blood sugar is higher than normal and not yet high enough to be diagnosed as type 2 diabetes. It is a warning sign that raises the risk of developing type 2 diabetes, heart disease, and stroke, and it can often be reversed with lifestyle changes.
What blood sugar levels mean prediabetes?
Prediabetes is diagnosed with an A1C of 5.7 to 6.4 percent, a fasting blood glucose of 100 to 125 mg/dL, or an oral glucose tolerance test result of 140 to 199 mg/dL. An A1C of 6.5 percent or higher, or a fasting glucose of 126 mg/dL or higher, points to diabetes.
Does prediabetes have symptoms?
Most people with prediabetes have no symptoms and do not know they have it. That is why blood testing is the only reliable way to find it. Some people notice darkened patches of skin on the neck or armpits. Risk factors such as excess weight, family history, and age make testing especially worthwhile.
Can prediabetes be reversed?
Yes, prediabetes can often be reversed. Losing a modest amount of weight, getting regular physical activity, and following a healthier eating plan can bring blood sugar back toward normal and lower the risk of type 2 diabetes. Avita MD builds a plan around these changes and tracks your progress.
How is prediabetes diagnosed and managed?
Prediabetes is diagnosed with a simple blood test, most often an A1C or a fasting glucose. Avita MD has on-site labs, so testing is convenient, and your provider focuses on lifestyle changes, monitors your numbers over time, and adds medication when appropriate to prevent progression to diabetes.
