Prediabetes and type 2 diabetes are two conditions. Both are related to blood sugar control. They happen at different stages.
Prediabetes happens when your blood sugar levels are higher than normal, but not high enough to be called diabetes. Type 2 diabetes happens when your blood sugar levels get too high and you need help.
It’s essential to know the difference because prediabetes can often be fixed. Type 2 diabetes is a long-term condition that needs ongoing care.
What Is Prediabetes?
Prediabetes is when your blood sugar levels are a bit high, but not high enough for type 2 diabetes. It usually happens because your body becomes resistant to insulin. Insulin is a hormone that helps move sugar from your blood into your cells.
Many people with prediabetes don’t have symptoms. That’s why it can go undetected for years. The Centers for Disease Control and Prevention (CDC) says that almost 8 out of 10 people with prediabetes don’t know they have it.
Prediabetes is like a warning sign. It means your body is starting to have trouble controlling blood sugar. You’re more likely to get type 2 diabetes.
What Is Type 2 Diabetes?
Type 2 diabetes is a long-term condition where your body can’t control blood sugar levels properly. This happens when your body either doesn’t respond to insulin or doesn’t make insulin.
As a result sugar builds up in your bloodstream of being used for energy. Unlike prediabetes type 2 diabetes needs help. If you don’t manage it high blood sugar can damage parts of your body.
Common problems from diabetes include issues with your:
- Eyes
- Kidneys
- Nerves
- Heart
- Blood vessels
Prediabetes vs Type 2 Diabetes: Main Differences
The main difference is how high your blood sugar levels are. Doctors use the A1C blood test to measure this. It shows your blood sugar levels over the past few months.

A1C Blood Sugar Ranges
Condition | A1C Level
| Normal blood sugar | Below 5.7% |
| Prediabetes | 5.7% – 6.4% |
Type 2 Diabetes | 6.5% or higher |
Symptoms: Is There a Difference?
There’s often a difference in symptoms between prediabetes and type 2 diabetes. Prediabetes usually doesn’t cause symptoms. Some people might get a skin condition called “acanthosis nigricans,” which causes skin patches in folds like your neck, armpits, or groin.
Type 2 diabetes is more likely to have symptoms like the following:
- increased thirst
- frequent urination
- fatigue
- blurred vision
- slow healing cuts or wounds
- numbness or tingling in your hands or feet
Can Prediabetes Turn Into Type 2 Diabetes?
Yes prediabetes can turn into type 2 diabetes if your blood sugar levels keep rising.. The good news is that you can often reverse prediabetes with lifestyle changes like:
- maintaining a healthy weight
- eating a balanced diet
- exercising more
- reducing sugar intake
- getting regular checkups
Treatment Differences
The treatment approach is different for prediabetes and type 2 diabetes. Prediabetes treatment focuses on lifestyle changes, not medication. For type 2 diabetes, you might need the following:
* regular blood sugar monitoring
* diabetes medications
* lifestyle changes
* health screenings

When Should You Get Tested?
You should consider testing if you:
- are overweight or obese
- have a family history of diabetes
- had gestational diabetes during pregnancy
- have high blood pressure or high cholesterol
- experience symptoms of high blood sugar
The American Diabetes Association recommends that most adults start diabetes screening at age 35, especially if they have risk factors.
Asked Questions (FAQ)
- Is prediabetes the same as diabetes?
No, prediabetes is not the same as diabetes. Prediabetes means your blood sugar levels are above normal but not high enough for a diabetes diagnosis.
- Can prediabetes become type 2 diabetes?
Yes, if your blood sugar levels keep rising and insulin resistance gets worse.
- Which condition is more serious?
Type 2 diabetes is generally more serious because blood sugar levels are higher and the risk of long-term complications is greater.
- Can prediabetes return to normal?
Yes, in cases healthy lifestyle changes can help bring blood sugar levels back to normal.
