The Ultimate Blood Sugar Levels Chart: Fasting, Post-Meal, and A1c Explained
Understanding your blood sugar levels is crucial for maintaining overall health and managing diabetes. This article provides a comprehensive blood sugar levels chart, explaining what's considered normal, pre-diabetic, and diabetic ranges for fasting blood sugar, post-meal blood sugar, and A1c. We'll also discuss factors that influence these levels and offer actionable insights to help you stay within a healthy range.
Why Monitoring Blood Sugar Levels Matters

Regular monitoring of your blood sugar levels offers several key benefits:
- Early Detection of Diabetes: Identifying elevated blood sugar early allows for lifestyle changes and interventions to prevent or delay the onset of type 2 diabetes.
- Effective Diabetes Management: For individuals with diabetes, monitoring helps track the effectiveness of medication, diet, and exercise in controlling blood sugar.
- Preventing Complications: Maintaining stable blood sugar levels reduces the risk of long-term complications associated with diabetes, such as heart disease, nerve damage, and kidney disease.
- Personalized Health Insights: Tracking blood sugar can provide valuable insights into how specific foods, activities, and stressors impact your glucose levels, enabling you to make informed choices about your health.
Understanding Fasting Blood Sugar Levels
Fasting blood sugar (FBS) is measured after an overnight fast (usually at least 8 hours). It provides a baseline reading of your glucose levels.
Here's a breakdown of fasting blood sugar levels:
- Normal: Less than 100 mg/dL
- Prediabetes: 100 to 125 mg/dL
- Diabetes: 126 mg/dL or higher (confirmed by a repeat test)
If your fasting blood sugar consistently falls within the prediabetes range, it's essential to consult your doctor to discuss preventative measures.

Understanding Post-Meal (Postprandial) Blood Sugar Levels
Post-meal blood sugar, also known as postprandial blood sugar, is measured 1-2 hours after eating a meal. It indicates how well your body is processing glucose from food.
Here's a breakdown of post-meal blood sugar levels:
- Normal (1 hour after eating): Less than 140 mg/dL
- Normal (2 hours after eating): Less than 120 mg/dL
- Prediabetes (1 hour after eating): 140 to 199 mg/dL
- Diabetes (1 hour after eating): 200 mg/dL or higher
It's important to note that target post-meal blood sugar levels can vary based on individual circumstances, such as age and overall health. Your doctor can help determine the appropriate targets for you.
Understanding A1c Levels
The A1c test, also known as the glycated hemoglobin test, provides an average of your blood sugar levels over the past 2-3 months. It gives a broader picture of your long-term glucose control.
Here's a breakdown of A1c levels:
- Normal: Less than 5.7%
- Prediabetes: 5.7% to 6.4%
- Diabetes: 6.5% or higher
For individuals with diabetes, the target A1c level is generally below 7%, but this can vary depending on individual circumstances. Discuss your target A1c with your healthcare provider.

Factors That Influence Blood Sugar Levels
Several factors can impact your blood sugar levels, including:
- Diet: Consuming high-carbohydrate and sugary foods can cause spikes in blood sugar.
- Physical Activity: Exercise helps lower blood sugar by increasing insulin sensitivity.
- Stress: Stress hormones can raise blood sugar levels.
- Medications: Certain medications, such as steroids, can affect blood sugar.
- Illness: Infections and illnesses can temporarily increase blood sugar.
- Dehydration: Not drinking enough water can lead to higher blood sugar concentrations.
- Sleep: Lack of sleep can impair insulin sensitivity and increase blood sugar levels.
Tips for Maintaining Healthy Blood Sugar Levels
Here are some actionable strategies to help you maintain healthy blood sugar levels:
- Eat a Balanced Diet: Focus on whole, unprocessed foods, including plenty of fruits, vegetables, and lean protein. Limit your intake of sugary drinks, processed foods, and refined carbohydrates.
- Engage in Regular Physical Activity: Aim for at least 30 minutes of moderate-intensity exercise most days of the week.
- Manage Stress: Practice stress-reducing techniques like meditation, yoga, or deep breathing exercises.
- Stay Hydrated: Drink plenty of water throughout the day.
- Get Enough Sleep: Aim for 7-8 hours of quality sleep each night.
- Monitor Your Blood Sugar Regularly: If you have diabetes or are at risk, monitor your blood sugar as directed by your doctor.
- Work with a Healthcare Professional: Consult with your doctor or a registered dietitian to develop a personalized plan for managing your blood sugar.
