Learning that your blood sugar is higher than normal can be confusing, especially when you hear terms like prediabetes and diabetes. While the two conditions are closely related, they are not the same. Understanding the difference can help you take steps to protect your long-term health.
At Philip Rabito, MD, Mount Sinai-trained, board-certified endocrinologist Dr. Philip Rabito and Kiran Srivastava, PA-C, provide expert care for prediabetes, diabetes, and insulin resistance throughout New York and Long Island.
What Is Prediabetes?
Prediabetes occurs when your blood sugar levels are higher than normal but not high enough for a diagnosis of Type 2 diabetes. It often develops because your body becomes resistant to insulin, making it harder for glucose to move from your bloodstream into your cells.
What Is Type 2 Diabetes?
Type 2 diabetes develops when insulin resistance becomes more severe, and your body can no longer keep blood sugar within a healthy range. Persistently high blood sugar can damage blood vessels, nerves, kidneys, eyes, and other organs if left untreated.
Prediabetes vs. Diabetes at a Glance
Both conditions involve elevated blood sugar, but they differ in severity and treatment needs:
| Feature | Prediabetes | Diabetes (Usually Type 2) |
| Blood Sugar Levels | Higher than normal | High enough for a diabetes diagnosis |
| Symptoms | Often no symptoms, though some people notice increased thirst, fatigue, or frequent urination | More likely to cause increased thirst, frequent urination, fatigue, blurred vision, and slow-healing wounds |
| Insulin Function | Insulin resistance begins | Insulin resistance worsens, and the body can no longer keep blood sugar within a healthy range |
| Long-Term Health Risks | Increased risk of developing Type 2 diabetes, heart disease, and stroke | Higher risk of nerve damage, kidney disease, vision loss, heart disease, and other complications if left untreated |
| Treatment | Lifestyle changes, weight management, and regular monitoring; medication may be recommended in some cases | Lifestyle changes, blood sugar monitoring, oral medications, injectable medications, and sometimes insulin therapy |
| Can It Be Reversed? | Blood sugar levels can often return to a healthy range with early intervention | Can often be well managed with significant lifestyle changes and medical care |
