Prediabetes and diabetes are closely related conditions, but they are not the same. Both involve problems with blood sugar regulation, but the blood glucose levels are different.
Prediabetes means that blood sugar is higher than normal but has not yet reached the diagnostic range for diabetes. Diabetes occurs when blood glucose reaches levels that meet the criteria for the condition.
Understanding the difference between diabetes and prediabetes is important because prediabetes can provide an opportunity to identify metabolic risk early and take appropriate action.
What Is Prediabetes?
Prediabetes is a condition where blood sugar levels are higher than the normal range but not high enough to be diagnosed as diabetes.
It is often associated with insulin resistance. When the body’s cells become less responsive to insulin, the pancreas may produce more insulin to compensate. Over time, blood glucose can begin to rise.
Prediabetes often does not cause noticeable symptoms, which means a person may have it without knowing.
Madhavbaug’s prediabetes care programme focuses on identifying metabolic factors associated with elevated blood sugar and insulin resistance.
What Is Diabetes?
Diabetes is a chronic metabolic condition in which blood glucose levels are too high.
There are different types of diabetes, including type 1 diabetes, type 2 diabetes and gestational diabetes.
Type 2 diabetes is the most common form. It usually develops when the body becomes resistant to insulin and, over time, the pancreas may not produce enough insulin to maintain healthy blood glucose levels.

Diabetes vs Prediabetes: What Is the Difference?
The main difference is the level of blood glucose.
One commonly used test is HbA1c, which reflects average blood sugar levels over approximately the previous three months.
The commonly used diagnostic ranges are:
| Test | Normal | Prediabetes | Diabetes |
|---|---|---|---|
| HbA1c | Below 5.7% | 5.7%-6.4% | 6.5% or higher |
| Fasting blood glucose | Below 100 mg/dL | 100-125 mg/dL | 126 mg/dL or higher |
A healthcare professional may recommend repeat testing or additional tests before confirming a diagnosis.
Is Prediabetes the Same as Early Diabetes?
No.
Prediabetes means blood sugar is above the normal range but below the diagnostic threshold for diabetes.
However, it should not be ignored. Prediabetes is associated with a higher risk of developing type 2 diabetes and cardiovascular disease.
Madhavbaug’s prediabetes page also highlights the relationship between prediabetes, insulin resistance, obesity, hypertension and cardiovascular risk.
This makes prediabetes an important stage for identifying and addressing metabolic risk factors.
What Causes Prediabetes and Type 2 Diabetes?
Prediabetes and type 2 diabetes can share several risk factors, including:
- Excess body weight or obesity
- Increased abdominal fat
- Physical inactivity
- Family history of diabetes
- Increasing age
- High blood pressure
- Abnormal cholesterol levels
- Insulin resistance
- Previous gestational diabetes
- Unhealthy dietary patterns
Having one or more risk factors does not mean that diabetes will definitely develop. However, they can make regular screening and preventive care more important.
What Are the Symptoms of Prediabetes?
Prediabetes is often silent.
Some people may experience fatigue, increased hunger, difficulty managing weight or increased thirst, but these symptoms are not specific to prediabetes.
This is why blood testing is more useful than relying on symptoms alone.
If you have risk factors for diabetes, discuss HbA1c or blood glucose testing with your healthcare professional.
What Are the Symptoms of Diabetes?
Symptoms can vary depending on blood glucose levels and the type of diabetes.
Possible symptoms include:
- Increased thirst
- Frequent urination
- Increased hunger
- Unexplained weight changes
- Fatigue
- Blurred vision
- Slow-healing wounds
Some people with type 2 diabetes may have few or no noticeable symptoms initially.
If you experience persistent symptoms or have diabetes risk factors, appropriate testing can help determine whether your blood glucose levels require further evaluation.
Can Prediabetes Be Improved?
Prediabetes can sometimes improve when contributing factors are addressed.
Regular physical activity, a balanced diet, appropriate weight management and regular monitoring can support healthier blood glucose levels.
The right approach depends on individual factors such as age, weight, blood sugar levels, medications, physical activity and other health conditions.
You can also read Madhavbaug’s diabetes control tips for practical information related to blood sugar management.
What Happens If Prediabetes Is Ignored?
Prediabetes does not automatically progress to diabetes. However, it indicates that blood sugar regulation is already changing.
If underlying risk factors continue, blood glucose may gradually increase and eventually reach the diagnostic range for type 2 diabetes.
Prediabetes can also occur alongside high blood pressure, abnormal cholesterol and excess abdominal fat. These factors can collectively contribute to metabolic syndrome.
Learn more about metabolic syndrome and how different metabolic risk factors can occur together.
How Can You Reduce Your Risk of Diabetes?
Some practical measures that may support better metabolic health include:
Stay physically active
Regular movement and exercise can support insulin sensitivity and blood glucose management.
Follow a balanced eating pattern
Focus on vegetables, whole grains, appropriate protein sources and minimally processed foods while limiting excessive added sugars and highly processed foods.
Maintain a healthy weight
If you have overweight or obesity, appropriate weight management may support improvements in metabolic health.
Madhavbaug also addresses the relationship between obesity, insulin resistance, diabetes and cardiovascular risk through its obesity management programme.
Monitor your health
Regular blood sugar, blood pressure and cholesterol checks can help identify metabolic risk factors early.
Frequently Asked Questions
Is prediabetes reversible?
Blood glucose levels in the prediabetes range may improve with appropriate lifestyle changes and healthcare guidance. Individual results vary.
What HbA1c level is considered prediabetes?
An HbA1c of 5.7% to 6.4% is generally classified as the prediabetes range.
Can you have prediabetes without symptoms?
Yes. Prediabetes often does not cause noticeable symptoms, which is why testing can be important for people with risk factors.
How long does prediabetes take to become diabetes?
There is no fixed timeline. Some people remain in the prediabetes range for years, while others may progress more quickly. Lifestyle, genetics, weight, physical activity and other health factors can influence risk.
Can losing weight help with prediabetes?
For people who have overweight or obesity, appropriate weight loss can improve insulin sensitivity and blood glucose control. The appropriate target varies between individuals.
Is diabetes worse than prediabetes?
They represent different stages of blood glucose dysregulation. Diabetes has reached a diagnostic threshold and requires ongoing management. Prediabetes indicates elevated risk and provides an opportunity for early intervention.
The Bottom Line
Prediabetes means blood sugar is higher than normal but has not reached the diagnostic range for diabetes. Diabetes occurs when blood glucose reaches the diagnostic range.
Prediabetes should not be ignored because it can indicate underlying insulin resistance and an increased risk of type 2 diabetes and cardiovascular disease.
If you have abnormal blood sugar, a family history of diabetes or other metabolic risk factors, speak with a qualified healthcare professional about appropriate testing and personalised care.
