Understanding Glucose

What is Glucose and Why Monitor It?

Glucose is a simple sugar that serves as the primary source of energy for the body. It circulates in the blood and is essential for the proper functioning of organs, especially the brain.

Why Monitor Glucose?

Monitoring blood glucose levels is crucial for:

  • Diagnosing diabetes and prediabetes
  • Managing existing diabetes
  • Preventing complications from abnormal glucose levels
  • Understanding how diet, exercise, and medication affect your body
  • Optimizing overall health and energy levels
Measurement Units
Understanding glucose measurement units

mmol/L

Millimoles per liter

International Standard

mg/dL

Milligrams per deciliter

US Standard

Conversion Formula:

1 mmol/L = 18 mg/dL

mg/dL ÷ 18 = mmol/L

Glucose Testing Methods
Different ways to measure blood glucose

Fingerstick (Capillary)

Most common self-testing method using a glucometer

Continuous Glucose Monitoring (CGM)

Provides real-time readings throughout the day and night

Laboratory Tests

Most accurate, used for diagnosis (fasting plasma glucose, A1C, OGTT)

Flash Glucose Monitoring

Sensor worn on the body that provides readings when scanned

Reference Values

Glucose Range Comparison

Understanding normal and abnormal glucose levels at different times is essential for proper management.

Fasting Blood Glucose (Before Meals)
Measured after at least 8 hours of fasting, typically in the morning before breakfast
ClassificationRange (mmol/L)
Normal
3.9 - 5.5
Prediabetes

Type 2 Diabetes
≥ 7.0
Type 1 Diabetes (Target)
4.0 - 7.0
Post-Meal Glucose (1-2 hours after eating)
Measured 1-2 hours after the start of a meal to assess how your body processes carbohydrates
ClassificationRange (mmol/L)
Normal
< 7.8
Prediabetes
7.8 - 11.0
Type 2 Diabetes
> 11.0
Type 1 Diabetes (Target)
5.0 - 10.0
Hourly Glucose Progression After Meals
