Your Blood Sugar Levels Chart: Decoding Prediabetes and Diabetes Ranges
Understanding your blood sugar levels is crucial for maintaining good health, especially when it comes to preventing or managing prediabetes and diabetes. This article breaks down everything you need to know about blood sugar levels, including normal ranges, what to do if your levels are too high or too low, and how to interpret the numbers on your blood sugar chart.
Why Blood Sugar Levels Matter
Blood sugar, or glucose, is the primary source of energy for your body. Insulin, a hormone produced by the pancreas, helps glucose from food get into your cells to be used for energy. When you have diabetes or prediabetes, your body either doesn’t make enough insulin or can’t use insulin properly, leading to elevated blood sugar levels. Uncontrolled blood sugar can lead to serious health complications, including heart disease, kidney disease, nerve damage, and vision problems.

Understanding Blood Sugar Readings
Blood sugar is typically measured in milligrams per deciliter (mg/dL) or millimoles per liter (mmol/L). There are several different types of blood sugar tests:
- Fasting Blood Sugar (FBS): This is measured after an overnight fast of at least 8 hours.
- Postprandial Blood Sugar (PPBS): This is measured 1-2 hours after eating a meal.
- Random Blood Sugar (RBS): This is measured at any time of day, regardless of when you last ate.
- A1C Test: This measures your average blood sugar levels over the past 2-3 months.

The following chart outlines the generally accepted ranges for blood sugar levels. Keep in mind that these ranges may vary slightly depending on individual factors and laboratory standards. It's crucial to consult with your doctor for personalized guidance.
| Test | Normal | Prediabetes | Diabetes |
|---|---|---|---|
| Fasting Blood Sugar (FBS) | Less than 100 mg/dL (5.6 mmol/L) | 100 to 125 mg/dL (5.6 to 6.9 mmol/L) | 126 mg/dL (7.0 mmol/L) or higher |
| Postprandial Blood Sugar (PPBS) (2 hours after eating) | Less than 140 mg/dL (7.8 mmol/L) | 140 to 199 mg/dL (7.8 to 11.0 mmol/L) | 200 mg/dL (11.1 mmol/L) or higher |
| A1C Test | Less than 5.7% | 5.7% to 6.4% | 6.5% or higher |
What Does Each Category Mean?
- Normal Blood Sugar: Indicates that your body is effectively regulating blood sugar and that you are not at risk for prediabetes or diabetes.
- Prediabetes: This means your blood sugar levels are higher than normal but not high enough to be diagnosed with diabetes. Prediabetes increases your risk of developing type 2 diabetes, heart disease, and stroke. Making lifestyle changes, such as diet and exercise, can often prevent or delay the onset of diabetes.
- Diabetes: This indicates that your body is not properly regulating blood sugar, and you need to manage your levels to avoid health complications.
Symptoms of High Blood Sugar (Hyperglycemia)
If your blood sugar is consistently high, you may experience the following symptoms:
- Increased thirst
- Frequent urination
- Blurred vision
- Fatigue
- Headaches
- Slow-healing sores
Symptoms of Low Blood Sugar (Hypoglycemia)
If your blood sugar drops too low, you may experience:
- Shakiness
- Sweating
- Dizziness
- Confusion
- Irritability
- Hunger
- Rapid heartbeat
- Seizures (in severe cases)
What To Do if Your Blood Sugar Is Too High or Too Low
High Blood Sugar (Hyperglycemia):
- Drink plenty of water: Dehydration can worsen hyperglycemia.
- Check your medication: If you take insulin or other diabetes medications, ensure you are taking the correct dose at the right time. Consult with your doctor.
- Exercise: Physical activity can help lower blood sugar. However, avoid exercise if you have ketones in your urine, as this can be dangerous.
- Contact your doctor: If your blood sugar remains high despite your efforts to lower it, seek medical advice.
Low Blood Sugar (Hypoglycemia):
- Eat or drink something sugary: Quickly consume 15-20 grams of fast-acting carbohydrates, such as glucose tablets, fruit juice, or regular soda.
- Recheck your blood sugar after 15 minutes: If it's still low, repeat the process.
- Eat a snack: Once your blood sugar returns to normal, eat a snack containing protein and carbohydrates, such as crackers with peanut butter or cheese.
- Contact your doctor: If you experience frequent episodes of hypoglycemia, your doctor may need to adjust your medication.
Factors That Can Affect Blood Sugar Levels
Several factors can influence your blood sugar levels, including:
- Diet: The types and amounts of food you eat have a direct impact on your blood sugar.
- Physical Activity: Exercise helps your body use glucose for energy.
- Stress: Stress hormones can raise blood sugar levels.
- Illness: Infections can cause blood sugar to fluctuate.
- Medications: Certain medications, such as steroids, can affect blood sugar.
- Sleep: Poor sleep can affect insulin sensitivity.
