The Complete Blood Sugar Levels Chart for Adults, With and Without Diabetes
Understanding your blood sugar levels is crucial for maintaining optimal health, especially if you're managing diabetes. This article provides a comprehensive guide to blood sugar levels, including normal ranges, what to expect with and without diabetes, and what to do if your levels are outside the target range. We'll cover everything from fasting blood sugar to postprandial blood sugar, equipping you with the knowledge you need to take control of your health.
Why is Monitoring Blood Sugar Important?
Blood sugar, or glucose, is the main sugar found in your blood and your body's primary source of energy. Monitoring your blood sugar levels is vital because consistently high or low levels can lead to serious health complications. Uncontrolled high blood sugar (hyperglycemia) can damage blood vessels, nerves, and organs, leading to problems like heart disease, kidney disease, vision loss, and nerve damage (neuropathy). Conversely, low blood sugar (hypoglycemia) can cause dizziness, confusion, seizures, and even loss of consciousness.

For individuals with diabetes, regular monitoring is essential for managing their condition and preventing these complications. For those without diabetes, understanding blood sugar levels can help identify early warning signs and encourage proactive lifestyle changes to prevent the development of the disease.
Normal Blood Sugar Levels for Adults Without Diabetes
Here's a general guideline for normal blood sugar levels in adults without diabetes. Keep in mind that these are just ranges, and your individual target might be slightly different.
- Fasting Blood Sugar: 70-99 mg/dL (3.9-5.5 mmol/L)
- 2 Hours After Eating (Postprandial): Less than 140 mg/dL (7.8 mmol/L)
- HbA1c: Less than 5.7%
If your blood sugar levels consistently fall within these ranges, you're generally considered to have healthy glucose metabolism.

Blood Sugar Levels for Adults with Diabetes
The target blood sugar levels for individuals with diabetes are different. The American Diabetes Association (ADA) provides the following guidelines:
- Fasting Blood Sugar: 80-130 mg/dL (4.4-7.2 mmol/L)
- 2 Hours After Eating (Postprandial): Less than 180 mg/dL (10.0 mmol/L)
- HbA1c: Less than 7% (although individual targets may vary depending on age, overall health, and other factors)
It's crucial for people with diabetes to work with their healthcare provider to determine their personalized blood sugar targets and management plan.
Understanding Blood Sugar Level Measurements: mg/dL vs. mmol/L
Blood sugar levels are typically reported in two units: milligrams per deciliter (mg/dL) and millimoles per liter (mmol/L). In the United States, mg/dL is the most common unit, while mmol/L is primarily used in other parts of the world. To convert from mg/dL to mmol/L, divide the mg/dL value by 18. For instance, 90 mg/dL is approximately equal to 5 mmol/L.
Complete Blood Sugar Levels Chart for Adults
This chart provides a comprehensive overview of blood sugar levels for adults, both with and without diabetes, covering fasting, postprandial (2 hours after eating), and HbA1c measurements.
| Measurement | Without Diabetes (mg/dL) | With Diabetes (mg/dL) | Interpretation |
|---|---|---|---|
| Fasting **Blood Sugar** | 70-99 | 80-130 | * Normal: Without diabetes, fasting levels are typically between 70-99 mg/dL. * Target Range: With diabetes, fasting levels are aimed at 80-130 mg/dL. |
| 2 Hours After Eating (**Postprandial**) | Less than 140 | Less than 180 | * Normal: Without diabetes, postprandial levels should be less than 140 mg/dL. * Target Range: With diabetes, postprandial levels are aimed at less than 180 mg/dL. |
| HbA1c | Less than 5.7% | Less than 7% (Individualized) | * Normal: HbA1c less than 5.7% indicates good **long-term blood sugar** control. * Target Range: HbA1c less than 7% is generally the target for people with diabetes, though individual targets may vary based on factors like age and overall health. |
What to Do If Your Blood Sugar Is Too High (Hyperglycemia)
If your blood sugar readings are consistently higher than your target range, it's essential to take action. Here are some steps you can take:
- Check your medication: Ensure you're taking your diabetes medication as prescribed. If you're unsure about the dosage or timing, contact your doctor or pharmacist.
- Adjust your diet: Limit sugary foods and drinks, and focus on eating balanced meals with plenty of fiber, fruits, and vegetables.
- Exercise: Physical activity can help lower blood sugar. Even a short walk can make a difference.
- Stay hydrated: Dehydration can increase blood sugar levels. Drink plenty of water throughout the day.
- Contact your healthcare provider: If your blood sugar remains high despite these efforts, consult your doctor for further evaluation and adjustments to your treatment plan.
What to Do If Your Blood Sugar Is Too Low (Hypoglycemia)
Low blood sugar can be dangerous and requires immediate attention. If you experience symptoms of hypoglycemia (such as shakiness, sweating, dizziness, confusion, or rapid heartbeat), take the following steps:
- Consume fast-acting carbohydrates: Eat or drink 15-20 grams of fast-acting carbohydrates, such as glucose tablets, juice, regular soda (not diet), or hard candies.
- Wait 15 minutes and recheck: After 15 minutes, recheck your blood sugar. If it's still low, repeat the process.
- Follow up with a snack: Once your blood sugar is back within the normal range, eat a small snack containing both carbohydrates and protein (such as crackers with peanut butter) to help stabilize your blood sugar.
- Contact your healthcare provider: If you experience frequent or severe episodes of hypoglycemia, consult your doctor to adjust your medication or treatment plan.
Factors Affecting Blood Sugar Levels
Several factors can influence your blood sugar levels, including:
- Food and Drink: The type, amount, and timing of meals and snacks play a significant role. Carbohydrates have the most significant impact on blood sugar.
- Physical Activity: Exercise can lower blood sugar, while inactivity can increase it.
- Medication: Insulin and other diabetes medications can affect blood sugar.
- Stress: Stress hormones can raise blood sugar levels.
- Illness: Infections and other illnesses can impact blood sugar.
- Hormones: Hormonal changes, such as those that occur during menstruation or pregnancy, can influence blood sugar.
- Sleep: Lack of sleep can affect blood sugar control.
- Dehydration: Staying hydrated helps maintain healthy blood sugar levels.
Monitoring Your Blood Sugar
Regular monitoring is a cornerstone of diabetes management and can be beneficial for anyone looking to understand their glucose metabolism. Here are some common methods for monitoring blood sugar:
- Blood Glucose Meter (Glucometer): A small, portable device that measures blood sugar from a drop of blood, typically obtained by pricking a fingertip.
- Continuous Glucose Monitor (CGM): A device that continuously tracks blood sugar levels throughout the day and night. A small sensor inserted under the skin measures glucose levels in the interstitial fluid.
- HbA1c Test: A blood test that provides an average of your blood sugar levels over the past 2-3 months. It doesn't require fasting.
Choosing the right method depends on your individual needs and preferences. Discuss the best option with your healthcare provider.
Preventing Blood Sugar Imbalances
Whether you have diabetes or not, adopting a healthy lifestyle can help prevent blood sugar imbalances. Here are some key strategies:
