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 |
