Are You in the Prediabetes Range? Understanding Your Diagnosis Levels
Prediabetes is a health condition where blood sugar levels are higher than normal but not high enough to be diagnosed as type 2 diabetes. It's a crucial warning sign that lifestyle changes are needed to prevent the development of full-blown diabetes. Understanding prediabetes diagnosis levels is the first step towards taking control of your health. Let's dive into the details.
What is Prediabetes?
Simply put, prediabetes means your body is struggling to process glucose (sugar) properly. Insulin, a hormone produced by your pancreas, helps glucose from food get into your cells to be used for energy. When you have prediabetes, your cells become resistant to insulin, and your pancreas can't produce enough insulin to overcome this resistance. As a result, glucose builds up in your blood.
The good news is that prediabetes is often reversible through diet, exercise, and sometimes medication.

Prediabetes Diagnosis Levels: The Key Indicators
There are three main blood tests used to diagnose prediabetes:

- Fasting Plasma Glucose (FPG) Test: Measures blood sugar after an overnight fast (at least 8 hours).
- Oral Glucose Tolerance Test (OGTT): Measures blood sugar before and 2 hours after you drink a sweet liquid.
- A1C Test (Glycated Hemoglobin): Reflects your average blood sugar level over the past 2-3 months.
Here’s a breakdown of the diagnostic ranges:
| Test | Normal | Prediabetes Range | Diabetes Range |
|---|---|---|---|
| Fasting Plasma Glucose (FPG) | Less than 100 mg/dL | 100 to 125 mg/dL | 126 mg/dL or higher |
| Oral Glucose Tolerance Test (OGTT) | Less than 140 mg/dL | 140 to 199 mg/dL | 200 mg/dL or higher |
| A1C Test | Less than 5.7% | 5.7% to 6.4% | 6.5% or higher |
- Fasting Plasma Glucose (FPG): A reading between 100 and 125 mg/dL indicates impaired fasting glucose, a type of prediabetes.
- Oral Glucose Tolerance Test (OGTT): A 2-hour glucose level between 140 and 199 mg/dL signifies impaired glucose tolerance, another form of prediabetes. This test is less commonly used for routine screening than the FPG or A1C test.
- A1C Test: An A1C level between 5.7% and 6.4% signifies prediabetes. It's a convenient test because it doesn't require fasting.
It's important to note that a diagnosis of prediabetes typically requires confirmation with a repeat test on a different day, especially if the initial result is only slightly elevated. Talk to your doctor about which test is best for you.

Who Should Get Tested for Prediabetes?
The American Diabetes Association recommends that everyone over the age of 45 be screened for prediabetes and diabetes. Earlier screening is recommended if you have risk factors, such as:
- Being overweight or obese (BMI of 25 or higher, or 23 or higher for Asian Americans)
- Having a family history of diabetes
- Having a sedentary lifestyle (little to no physical activity)
- Having a history of gestational diabetes (diabetes during pregnancy)
- Having high blood pressure or high cholesterol
- Being of certain ethnicities (African American, Hispanic/Latino American, American Indian, Alaska Native, Pacific Islander)
- Having Polycystic Ovary Syndrome (PCOS)
- Having a history of cardiovascular disease
What Happens if You're Diagnosed with Prediabetes?
A diagnosis of prediabetes is not a life sentence! It's an opportunity to take action and reduce your risk of developing type 2 diabetes. Here's what you should do:
- Work with Your Doctor: Develop a plan that includes lifestyle changes and, if necessary, medication. Your doctor may recommend regular monitoring of your blood sugar levels.
- Make Dietary Changes: Focus on eating a healthy diet that is low in saturated fat, trans fat, cholesterol, and added sugars. Increase your intake of fruits, vegetables, and whole grains. Consider working with a registered dietitian to create a personalized meal plan.
- Increase Physical Activity: Aim for at least 150 minutes of moderate-intensity aerobic exercise per week, such as brisk walking, cycling, or swimming. Incorporate strength training exercises at least twice a week.
- Lose Weight (if overweight or obese): Even a small amount of weight loss (5-7% of your body weight) can make a big difference in your blood sugar levels.
- Consider Medication (if recommended by your doctor): Metformin is a medication commonly prescribed to people with prediabetes to help improve insulin sensitivity and lower blood sugar levels.
- Monitor Blood Sugar Regularly: Regular monitoring of blood sugar levels, as advised by your healthcare provider, can help track progress and adjust management strategies accordingly.
The Importance of Early Detection and Prevention
Early detection and management of prediabetes are crucial for preventing the development of type 2 diabetes and its associated complications, such as heart disease, nerve damage, kidney damage, and vision problems. By understanding the prediabetes range, recognizing your risk factors, and making lifestyle changes, you can significantly improve your health and well-being.
Take charge of your health today. Talk to your doctor about getting screened for prediabetes if you have risk factors or are over the age of 45.
