13 Sep 2025What Is a Normal Blood Sugar Level? Your Ultimate Blood Sugar Chart
Understanding your blood sugar levels is crucial for maintaining good health, especially if you have diabetes or are at risk of developing it. Knowing the normal ranges and what to do when your levels are outside of these ranges can significantly impact your overall well-being. This guide provides a comprehensive blood sugar chart and explains everything you need to know about maintaining healthy glucose levels.
Why Blood Sugar Levels Matter
Blood sugar, or glucose, is your body's primary source of energy. It comes from the food you eat, and your pancreas produces insulin to help move glucose from your blood into your cells for energy. When this process is disrupted, such as in diabetes, glucose can build up in the bloodstream, leading to various health complications. Monitoring your blood sugar levels helps you and your healthcare provider manage these complications and optimize your health. Feeling Shaky Understanding The Symptoms Of Low Blood Sugar Hypoglycemia
Factors Affecting Blood Sugar Levels
Several factors can influence your blood sugar levels. These include:
- Food Intake: The types and amount of food you eat significantly impact your blood sugar. High-carbohydrate foods can cause spikes.
- Physical Activity: Exercise can help lower blood sugar as your body uses glucose for energy.
- Medications: Certain medications, especially those for diabetes, directly affect blood sugar levels.
- Stress: Stress hormones can raise blood sugar levels.
- Illness: Illness can affect your body's ability to regulate blood sugar.
- Time of Day: Blood sugar levels can fluctuate throughout the day.
Blood Sugar Chart: Understanding the Numbers
It's essential to understand the different ranges for normal blood sugar levels depending on the time of day and your health status. The following chart provides general guidelines:
Category | Fasting Blood Sugar (mg/dL) | 2 Hours After Eating (mg/dL) | HbA1c (%) |
---|---|---|---|
Normal (Without Diabetes) | Less than 100 | Less than 140 | Less than 5.7% |
Prediabetes | 100 to 125 | 140 to 199 | 5.7% to 6.4% |
Diabetes | 126 or higher | 200 or higher | 6.5% or higher |
Note: These values can vary based on individual circumstances and specific guidelines from your healthcare provider. Always consult with a professional for personalized advice. Blood Sugar Support Supplements An Evidence Based Guide
Fasting Blood Sugar
Fasting blood sugar is measured after at least eight hours of not eating. It provides a baseline level of glucose in your blood.
Blood Sugar 2 Hours After Eating
This measurement indicates how well your body processes glucose from a meal. It helps determine if your insulin response is adequate.
HbA1c
The HbA1c test provides an average of your blood sugar levels over the past 2-3 months. It gives a longer-term perspective on blood sugar control.
What to Do if Your Blood Sugar Is High
If your blood sugar is consistently high (hyperglycemia), take the following steps:
- Check Your Blood Sugar More Frequently: Monitor your levels to understand trends.
- Stay Hydrated: Drink plenty of water to help flush out excess glucose.
- Adjust Your Diet: Avoid sugary drinks and high-carbohydrate snacks.
- Exercise: Engage in light physical activity to help lower blood sugar.
- Review Your Medications: If you take diabetes medication, ensure you're following your prescribed dosage. Contact your healthcare provider if levels remain high.
What to Do if Your Blood Sugar Is Low
If your blood sugar is too low (hypoglycemia), take immediate action:
- Eat or Drink Something Sugary: Consume 15-20 grams of fast-acting carbohydrates like glucose tablets, fruit juice, or hard candy.
- Wait 15 Minutes: Recheck your blood sugar after 15 minutes.
- Repeat if Necessary: If your blood sugar is still low, repeat the process.
- Eat a Meal or Snack: Once your blood sugar returns to normal, eat a meal or snack to prevent another drop.
Monitoring Your Blood Sugar
Regular blood sugar monitoring is essential for people with diabetes and those at risk. Here are a few ways to monitor:
- Blood Glucose Meter: This is the most common method, involving a finger prick to collect a blood sample.
- Continuous Glucose Monitor (CGM): A CGM uses a sensor inserted under the skin to continuously track glucose levels.
- Regular Check-ups with Your Doctor: Routine visits can help monitor your overall health and blood sugar control.
Lifestyle Changes to Maintain Healthy Blood Sugar

Making healthy lifestyle choices can significantly impact your blood sugar levels:
- Balanced Diet: Focus on whole grains, lean proteins, and plenty of fruits and vegetables. Limit sugary and processed foods.
- Regular Exercise: Aim for at least 30 minutes of moderate-intensity exercise most days of the week.
- Weight Management: Maintaining a healthy weight can improve insulin sensitivity.
- Stress Management: Practice relaxation techniques like meditation or yoga.
- Adequate Sleep: Aim for 7-8 hours of quality sleep each night.
