When was your last blood sugar check? If it has been a while, you may want to reconsider. A new diabetes study has revealed that nearly half of people living with the condition don’t know they have it—an alarming trend with serious health consequences.

The staggering numbers

According to findings published in The Lancet Diabetes & Endocrinology, 44% of people aged 15 and above with diabetes remain undiagnosed. The analysis covered 204 countries and tracked trends from 2000 to 2023, making it one of the most comprehensive global studies of its kind.

Lead researcher Lauryn Stafford explained that the majority of these undiagnosed cases involve type 2 diabetes, the more common form of the disease. Globally, one in nine adults lives with diabetes, according to the International Diabetes Federation. In the United States alone, about 11.6% of the population has been diagnosed.

Why younger people are missing diagnoses

The study found that younger people are significantly less likely to know they have diabetes compared to older adults. Only about 20% of people under 35 with diabetes are aware of their condition. Routine screenings often focus on adults aged 35 and older, leaving many young people overlooked.

“You can live with high glucose levels for years without realizing it,” Stafford said. “Diagnosis often happens only when complications develop.”

Why early diagnosis matters

Early detection is crucial. As Dr. Rita Kalyani of Johns Hopkins University explained, diagnosing diabetes promptly allows for timely treatment and prevention of long-term complications. These can include heart disease, kidney damage, nerve pain, and even vision loss.

Despite available treatments, outcomes remain concerning. In 2023, only 40% of people receiving diabetes care were effectively managing their blood sugar. Experts say coexisting conditions like hypertension or kidney disease often complicate treatment.

Recognizing symptoms early

Many people with diabetes show no signs in the early stages. Still, doctors urge awareness of common symptoms such as fatigue, blurry vision, frequent urination, excessive thirst or hunger, and sudden weight loss. If you notice these or have a family history of diabetes, a blood glucose screening can make all the difference.

Can diabetes be prevented?

While type 1 diabetes cannot be prevented, type 2 diabetes risk can be reduced through lifestyle choices. Shifting to a Mediterranean or plant-forward diet, reducing red and processed meats, avoiding highly processed foods, and adding daily physical activity—like 15 minutes of brisk walking—can all help lower the risk.

As Stafford put it: “Prevention is just as critical as diagnosis. Addressing risk factors today means fewer cases tomorrow.”

A global call to action

This study highlights more than numbers—it raises an urgent call for awareness, routine screenings, and lifestyle shifts. With nearly half of cases hidden from view, the battle against diabetes begins with knowledge and timely action.

Fundraiser Supports Seniors Living with Diabetes

A new endurance charity event on Prince Edward Island—the Glucose Grind—raised over $9,000 this past weekend to support seniors living with diabetes. The event, held Saturday, attracted dozens of participants aiming to raise awareness and funds for Islanders who face the financial burdens of managing the chronic condition.

Route Stretches from Kensington to Charlottetown

The inaugural Glucose Grind spanned 65 kilometres, beginning in Kensington and ending in downtown Charlottetown. Participants had the flexibility to complete the route solo or in teams, whether by running, biking, or walking. The event took runners and walkers through rural stretches and urban centres, highlighting both the beauty and the solidarity of the Island’s communities.

Personal Motivation Behind the Mission

Organizer Geoff Kowalski, a long-distance runner and Type 1 diabetic, launched the event in collaboration with the Community Foundation of Prince Edward Island. Having firsthand experience with the high costs of diabetes management, Kowalski was motivated to act. “Many Island seniors are struggling—not just with insulin or glucose monitors—but with the basics like food security,” he said. He completed the entire route in just under 7.5 hours.

Rising Costs of Diabetes Management

Kowalski emphasized the financial weight of living with diabetes. A continuous glucose monitor alone can cost around $300 a month, not including insulin, needles, or dietary needs. “If you’re low income or retired, these expenses pile up fast,” he noted. The idea for the Glucose Grind stemmed from stories shared by his wife, a diabetic nurse educator, who often sees seniors sacrificing nutrition for affordability.

Shared Experience Among Islanders

Among the participants was Mike Hogan, an Island resident diagnosed with Type 1 diabetes last year. He echoed Kowalski’s concerns about the cost of healthy eating. “Processed foods are cheaper, but diabetics don’t have the luxury of eating whatever is affordable,” he said. Hogan, also a runner, has entered the 2025 Bath Half Marathon in the UK to support further diabetes research. He’s training for the Boston Marathon, requiring a qualifying time of 3:10:00.

Community Impact and Future Plans

The funds raised will go toward assisting low-income seniors on the Island in covering expenses for essential diabetes care. Kowalski and the Community Foundation hope to make the Glucose Grind an annual event, expanding its reach and support each year. “This is just the beginning,” Kowalski said. “The Island community came together this weekend—and we’ve proven that small steps lead to lasting impact.”
