A staggering one-third of the U.S. population has diabetes or prediabetes1, and if left untreated, diabetes can lead to serious health issues including life-threatening complications.2 Stable glucose levels are essential for diabetes management3, yet only 10% of people with Type 2 diabetes* or prediabetes say they understand the factors that cause changes in their glucose “extremely well.”4 With diabetes on the rise and awareness on the decline, the time is now to close this knowledge gap and help millions get glucose aware.
History of National Glucose Awareness Week
Glucose is sugar that circulates in your body, serving as the primary fuel source for your body’s cells. It powers everything from your brain’s thought processes to your muscles’ movements during daily activities.5
Your body relies on stable glucose levels to function optimally. From providing energy for your cells to supporting vital organ function, glucose plays a critical role in your overall health and well-being.
Understanding glucose and keeping glucose levels stable is especially important for the more than 125 million Americans living with diabetes or prediabetes – but a recent survey found only 10% of people with Type 2 diabetes* or prediabetes said they understand the factors that cause changes in their glucose levels “extremely well.”4
Dexcom, the global leader in real-time continuous glucose monitoring for people with diabetes, established National Glucose Awareness Week from September 22-28, 2025. National Glucose Awareness Week will help close the glucose knowledge gap and encourage people to take action to own their glucose health.

National Glucose Awareness Week timeline
German chemist Andreas Marggraf is the first person to discover glucose through grapes.
French Chemist André Dumas coins the term glucose, derived from the Greek word ‘gleukos’ referring to the sweet compound obtained from honey and grapes.
British scientist Sir Edward Albert Sharpey-Schafer discovers that people with diabetes have a problem with insulin. Insulin is a hormone that helps control glucose sugar in the blood. If your body doesn't use insulin properly, it can lead to diabetes.
Glucose monitors that require painful fingersticks become available, allowing people with diabetes and prediabetes to check their blood sugar levels at home.
The Food and Drug Administration clears Dexcom G6 for people with diabetes,
the first real-time continuous glucose monitor (CGM) to eliminate the need for
fingersticks.
For the first time without a prescription, millions of people can access glucose biosensing technology – a revolutionary tool for glucose tracking made easy.

A whopping 20% of people with Type 2 diabetes and 80% of those with prediabetes are undiagnosed, meaning they don’t even know they need to pay attention to their glucose levels.1
Lack of glucose awareness
More than 1 in 10 (15%) people with Type 2 diabetes* or prediabetes say they have no understanding of metabolic health4—of which glucose is a key indicator.
Confusion around glucose management
Since receiving their diagnosis, 45% of people with Type 2 diabetes* and prediabetes have faced confusion around how to effectively manage the condition, and half have faced decreased confidence in their overall health.4
Why National Glucose Awareness Week is Important
Diabetes is a growing epidemic in the U.S.
A staggering one-third of the U.S. population has diabetes or prediabetes1, and if left untreated, diabetes can lead to serious health issues including life-threatening complications.2
National Glucose Awareness Week activities motivate and encourage
National Glucose Awareness Week encourages people to learn about the importance of glucose on health and to take action to own their glucose health.
Glucose biosensing easily tracks glucose
Glucose biosensors reveal how food, exercise and sleep affect glucose and provide easy-to-understand insights to help people better monitor their glucose. Now, for the first time without a prescription in the U.S., millions of people can access glucose biosensing technology.
