Prediabetes is your body’s warning sign. It means your blood sugar is higher than normal but not yet in the diabetes range. Many people ignore it because they don’t feel sick, but prediabetes is already putting stress on your kidneys. The good news? It’s not too late. By taking action now, you can prevent diabetes, protect your kidneys, and avoid serious complications down the road.
How Prediabetes Affects Kidney Health
When blood sugar levels stay too high, even in the “prediabetes” range, your kidneys have to work harder to filter waste from your blood. Over time, this extra work damages the tiny blood vessels inside your kidneys. You may not notice symptoms yet, but the damage can build quietly. If prediabetes turns into diabetes, your risk of chronic kidney disease (CKD), dialysis, or even a kidney transplant increases.
The key message is this: prediabetes is the turning point. If you act now, you can protect your kidneys and prevent future complications.
Signs and Steps You Can Take Today
Prediabetes often has no obvious symptoms. But certain risk factors increase your chances of developing it — and that’s where action matters most.
You may be at risk if you:
- Carry extra weight, especially around your stomach
- Have high blood pressure
- Have a family history of diabetes or kidney disease
- Live a mostly inactive lifestyle
If these sound familiar, here’s what you can start doing now:
- Get tested regularly. Simple blood and urine tests can check blood sugar and kidney function.
- Choose kidney-friendly foods. Limit processed foods, sugary drinks, and too much salt.
- Move your body. Walking 30 minutes a day can lower blood sugar and blood pressure.
- Work with a healthcare provider. A nephrologist can guide you in protecting your kidneys before problems begin.
