The Complete Blood Sugar Levels Chart: Normal to Diabetes Range (mg/dL & mmol/L)

Understanding your blood sugar levels is crucial for maintaining good health, especially if you are at risk for or have been diagnosed with diabetes. This comprehensive guide provides a detailed blood sugar levels chart, covering normal ranges, prediabetes, and diabetes ranges in both milligrams per deciliter (mg/dL) and millimoles per liter (mmol/L). We'll explore the various types of blood sugar tests and what the results mean for your overall health.

Why Monitor Your Blood Sugar?

Monitoring your blood sugar helps you understand how food, exercise, and medications affect your glucose levels. Keeping your blood glucose within the target range can prevent or delay long-term health problems, such as heart disease, kidney disease, and nerve damage. Regular monitoring is especially important for individuals with diabetes, prediabetes, or those with a family history of diabetes. Furthermore, understanding the different blood sugar level charts allows you to better interpret test results and make informed decisions about your healthcare.

Blood Sugar Levels Chart: At a Glance

This chart provides a general overview of blood sugar levels for people with and without diabetes. Remember that these are general guidelines, and your healthcare provider may have specific targets for you based on your individual health needs.

Category	Fasting Blood Sugar (mg/dL)	Fasting Blood Sugar (mmol/L)	2-Hour Postprandial (After Meal) (mg/dL)	2-Hour Postprandial (After Meal) (mmol/L)
Normal	70-99	3.9-5.5	Less than 140	Less than 7.8
Prediabetes	100-125	5.6-6.9	140-199	7.8-11.0
Diabetes	126 or higher	7.0 or higher	200 or higher	11.1 or higher

Types of Blood Sugar Tests

Several types of blood sugar tests are used to diagnose and monitor diabetes. Each test provides different insights into your blood glucose levels. Here’s a breakdown:

Fasting Blood Sugar (FBS): Measured after at least eight hours of fasting. This test is often used to screen for diabetes and prediabetes. A normal fasting blood sugar is typically below 100 mg/dL (5.6 mmol/L).
Postprandial Blood Sugar (PPBS): This test measures blood sugar levels two hours after starting a meal. It helps determine how well your body processes glucose after eating. Normal postprandial blood sugar should be less than 140 mg/dL (7.8 mmol/L).
Random Blood Sugar Test: This test is taken at any time of day, regardless of when you last ate. It's often used when symptoms of diabetes are present. A random blood sugar level of 200 mg/dL (11.1 mmol/L) or higher, along with symptoms like increased thirst and frequent urination, may indicate diabetes.
A1C Test (Glycated Hemoglobin Test): This test provides an average of your blood sugar levels over the past 2-3 months. It measures the percentage of blood sugar attached to hemoglobin, the protein in red blood cells that carries oxygen. An A1C of 6.5% or higher indicates diabetes. The A1C is crucial for long-term diabetes management.

Understanding Normal Blood Sugar Levels

For individuals without diabetes, maintaining normal blood sugar levels is essential for overall health. Here’s a more detailed look at what’s considered normal:

Fasting Blood Sugar: Typically ranges from 70 to 99 mg/dL (3.9 to 5.5 mmol/L).
Postprandial Blood Sugar: Should be less than 140 mg/dL (7.8 mmol/L) two hours after eating.
A1C: Below 5.7%.

Maintaining normal blood sugar helps prevent insulin resistance, weight gain, and the development of type 2 diabetes. Regular physical activity and a balanced diet are crucial for keeping your blood glucose within the normal range.

Prediabetes: What You Need to Know

Prediabetes means that your blood sugar levels are higher than normal but not high enough to be diagnosed as diabetes. It’s a critical stage where lifestyle changes can make a significant difference.

Fasting Blood Sugar: Between 100 and 125 mg/dL (5.6 to 6.9 mmol/L).
Postprandial Blood Sugar: Between 140 and 199 mg/dL (7.8 to 11.0 mmol/L) two hours after eating.
A1C: Between 5.7% and 6.4%.

If you have prediabetes, adopting a healthy lifestyle, including diet and exercise, can often prevent or delay the onset of type 2 diabetes. Losing a modest amount of weight (5-7% of your body weight) and engaging in regular moderate-intensity exercise (like brisk walking for 30 minutes most days of the week) can significantly reduce your risk.

Diabetes Blood Sugar Levels

If your blood sugar levels consistently fall into the diabetes range, it’s essential to work closely with your healthcare provider to manage the condition. Here are the criteria for diagnosing diabetes:

Fasting Blood Sugar: 126 mg/dL (7.0 mmol/L) or higher on two separate tests.
Postprandial Blood Sugar: 200 mg/dL (11.1 mmol/L) or higher two hours after eating during an oral glucose tolerance test.
Random Blood Sugar: 200 mg/dL (11.1 mmol/L) or higher, along with symptoms of diabetes.
A1C: 6.5% or higher.

Effective diabetes management typically involves a combination of lifestyle modifications, medication (if needed), and regular blood sugar monitoring. The goal is to keep your blood glucose levels as close to the target range as possible to prevent complications.

Converting Blood Sugar Units: mg/dL to mmol/L

Understanding how to convert blood sugar units from mg/dL to mmol/L (and vice versa) can be helpful. The conversion factor is:

To convert mg/dL to mmol/L, divide by 18.
To convert mmol/L to mg/dL, multiply by 18.

For example:

100 mg/dL = 5.5 mmol/L (approximately)
7 mmol/L = 126 mg/dL (approximately)

Factors Affecting Blood Sugar Levels

Numerous factors can influence your blood sugar levels, including:

Diet: Carbohydrate intake has the most significant impact on blood glucose.
Exercise: Physical activity can lower blood sugar as your muscles use glucose for energy.
Medications: Certain medications, like steroids, can raise blood sugar.
Stress: Stress hormones can increase blood glucose levels.
Illness: Being sick can also raise blood sugar.
Dehydration: Can lead to higher blood sugar concentrations.
Menstrual Cycles and Hormonal Changes: Can influence blood sugar levels in women.

Tips for Managing Blood Sugar Levels

Here are some practical tips for managing your blood sugar effectively:

Follow a Healthy Diet: Focus on whole grains, lean proteins, fruits, and vegetables. Limit 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.
Monitor Your Blood Sugar Regularly: Use a blood glucose meter as directed by your healthcare provider.
Take Medications as Prescribed: If you have diabetes, adhere to your medication regimen.
Stay Hydrated: Drink plenty of water throughout the day.
Manage Stress: Practice relaxation techniques like meditation or deep breathing exercises.
Get Enough Sleep: Aim for 7-8 hours of quality sleep each night.

When to See a Doctor

It’s essential to consult your healthcare provider if you experience:

Consistently high or low blood sugar levels.
Symptoms of diabetes, such as frequent urination, excessive thirst, unexplained weight loss, or blurred vision.
Difficulty managing your blood sugar despite following a treatment plan.
Changes in your health that affect your blood glucose.

Regular check-ups and screenings are crucial for early detection and management of diabetes.
