Blood Sugar Levels Chart: Understanding mg/dL vs. mmol/L Readings

Understanding your blood sugar levels is crucial for managing diabetes and maintaining overall health. Different countries and regions use different units of measurement, primarily milligrams per deciliter (mg/dL) and millimoles per liter (mmol/L). This article provides a comprehensive blood sugar levels chart, explains the differences between mg/dL and mmol/L, and offers guidance on interpreting your readings.

Why is Monitoring Blood Sugar Important?

Monitoring your blood sugar levels helps you and your healthcare provider:

Determine how your body responds to different foods, exercise, and medications.
Identify patterns in your blood sugar levels.
Make necessary adjustments to your diet, exercise routine, or medication.
Reduce the risk of long-term complications associated with diabetes, such as nerve damage, kidney damage, and heart disease.

Understanding mg/dL and mmol/L

mg/dL (milligrams per deciliter): This is the standard unit used primarily in the United States and some other countries. It represents the concentration of glucose in a specific volume of blood.
mmol/L (millimoles per liter): This is the standard unit used in most other parts of the world, including Canada, Europe, and Australia. It also represents the concentration of glucose in a specific volume of blood, but it uses a different scale.

To convert between the two, use the following formulas:

To convert mg/dL to mmol/L: Divide mg/dL by 18 (approximately).
To convert mmol/L to mg/dL: Multiply mmol/L by 18 (approximately).

Blood Sugar Levels Chart: Target Ranges

This blood sugar levels chart provides general guidelines. Your target range may vary depending on your individual circumstances, health conditions, and age. Consult with your healthcare provider for personalized advice.

Category	mg/dL	mmol/L	Interpretation
Fasting Blood Sugar (Before Meal)	70-100 mg/dL	3.9-5.6 mmol/L	Normal
Fasting Blood Sugar (Before Meal)	100-125 mg/dL	5.6-6.9 mmol/L	Prediabetes
Fasting Blood Sugar (Before Meal)	126 mg/dL or higher	7.0 mmol/L or higher	Diabetes
2 Hours After Eating	Less than 140 mg/dL	Less than 7.8 mmol/L	Normal
2 Hours After Eating	140-199 mg/dL	7.8-11.0 mmol/L	Prediabetes
2 Hours After Eating	200 mg/dL or higher	11.1 mmol/L or higher	Diabetes
HbA1c (3-month average)	Less than 5.7%		Normal
HbA1c (3-month average)	5.7 - 6.4%		Prediabetes
HbA1c (3-month average)	6.5% or higher		Diabetes

Important Considerations Regarding the Chart:

These are general guidelines; consult your healthcare provider for personalized targets.
Individual targets may vary based on age, medical history, and overall health status.
HbA1c is a blood test that provides an average of your blood sugar control over the past 2-3 months.
Consistently high blood sugar levels can lead to long-term health complications.

Factors Affecting Blood Sugar Levels

Several factors can influence your blood sugar levels, including:

Diet: The types and amount of carbohydrates you consume.
Physical Activity: Exercise helps lower blood sugar.
Medications: Insulin and oral diabetes medications.
Stress: Stress hormones can raise blood sugar.
Illness: Infections can increase blood sugar levels.
Dehydration: Not drinking enough water can raise blood sugar.
Menstrual Cycle: Hormonal changes during menstruation can affect blood sugar.
Alcohol: Can cause blood sugar to initially rise and then drop.

Tips for Maintaining Healthy Blood Sugar Levels

Follow a Balanced Diet: Focus on whole, unprocessed foods, including fruits, vegetables, whole grains, and lean protein.
Exercise Regularly: Aim for at least 150 minutes of moderate-intensity exercise per week.
Monitor Your Blood Sugar Regularly: Check your blood sugar as recommended by your healthcare provider.
Take Medications as Prescribed: Follow your doctor's instructions for taking insulin or other diabetes medications.
Stay Hydrated: Drink plenty of water throughout the day.
Manage Stress: Practice stress-reduction techniques, such as yoga, meditation, or deep breathing exercises.
Get Enough Sleep: Aim for 7-8 hours of quality sleep each night.
Limit Alcohol Consumption: If you choose to drink alcohol, do so in moderation and with food.
Work Closely with Your Healthcare Provider: Schedule regular check-ups and discuss any concerns you have about your blood sugar levels.

When to Seek Medical Attention

Seek immediate medical attention if you experience any of the following:

Severe Hypoglycemia (Low Blood Sugar): Symptoms include confusion, dizziness, seizures, or loss of consciousness.
Severe Hyperglycemia (High Blood Sugar): Symptoms include excessive thirst, frequent urination, blurred vision, nausea, or vomiting.
Diabetic Ketoacidosis (DKA): A serious complication of diabetes characterized by high blood sugar, ketones in the urine, and symptoms such as abdominal pain, fruity-smelling breath, and rapid breathing.
