Prediabetes and Controlling Your Blood Sugar: What You Can Do
October 7th, 2025 | 2 min. read

Prediabetes is more common than you might think – more than 1 in 3 adults in the United States have it, and most don’t even know. The good news? With simple lifestyle changes, early prediabetes can be reversed.
Knowing your risk and making small, consistent changes can help you address prediabetes, avoid type 2 diabetes, and live a healthier life.
What is prediabetes?
If you have prediabetes, then your blood sugar is higher than normal, but not high enough to be diagnosed as type 2 diabetes. It’s a sign that your body isn’t efficiently processing glucose, but it’s also a chance to act before things progress. A simple blood test from your provider can tell you if you’re at risk for prediabetes.
Risk factors for prediabetes include:
- Being overweight
- Being 45 or older
- Having a family history of type 2 diabetes
- Being physically inactive
- Having a history of gestational diabetes
How prediabetes becomes type 2 diabetes
Without intervention, your body can become more resistant to insulin or stop making enough of it over time. As a result, your blood sugar levels may continue to rise and eventually cross from prediabetes into a type 2 diabetes diagnosis.
Thankfully, simple lifestyle changes such as healthy eating, regular physical activity, and weight loss can help stop the progression from prediabetes to type 2 diabetes.
How to keep prediabetes from progressing
These practical lifestyle changes can help lower your blood sugar and reduce your risk for type 2 diabetes:
- Get active: Aim for at least 30 minutes of moderate activity a day, 5 days a week
- Eat balanced meals: Focus on a healthy balance of whole grains, vegetables, lean proteins, and fewer added sugars
- Lose a little weight: Losing just 5–7% of your body weight can make a big difference
- Focus on overall well-being: Improving sleep and stress management can affect your blood sugar
