The Complete Blood Sugar Range Chart for Adults
Understanding your blood sugar levels is crucial for maintaining overall health and preventing complications. This guide provides a comprehensive overview of blood sugar ranges, what they mean, and how to interpret them. We've broken down everything from fasting levels to post-meal readings and A1C, ensuring you have the information needed to take control of your metabolic wellness.
Understanding Blood Sugar: The Basics
Your blood sugar, also known as glucose, is the primary source of energy for your body. It comes from the food you eat and is regulated by insulin, a hormone produced by the pancreas. Maintaining healthy blood sugar levels is essential for preventing long-term health problems.
Fasting Blood Sugar Range
Fasting blood sugar is measured after not eating for at least 8 hours, typically overnight. Here’s a breakdown of what the readings signify:
- Normal: Less than 100 mg/dL (5.6 mmol/L)
- Prediabetes: 100 to 125 mg/dL (5.6 to 6.9 mmol/L) - This indicates a higher than normal risk of developing type 2 diabetes.
- Diabetes: 126 mg/dL (7.0 mmol/L) or higher on two separate tests - This confirms a diagnosis of diabetes.
Post-Meal Blood Sugar Range (2 Hours After Eating)
Post-meal readings provide insight into how your body processes glucose after consuming food.
- Normal: Less than 140 mg/dL (7.8 mmol/L)
- Prediabetes: 140 to 199 mg/dL (7.8 to 11.0 mmol/L)
- Diabetes: 200 mg/dL (11.1 mmol/L) or higher - This often requires further investigation.
A1C Chart: Long-Term Blood Sugar Control
The A1C test provides an average of your blood sugar levels over the past 2-3 months. It’s a valuable tool for long-term diabetes management.
- Normal: Below 5.7%
- Prediabetes: 5.7% to 6.4% - Indicates an increased risk of developing diabetes.
- Diabetes: 6.5% or higher – Confirms a diabetes diagnosis.
