Who would you say is the greatest Canadian of all time?
The CBC TV series “The Greatest Canadian” put Tommy Douglas — aka the “Father of Medicare” — at the top of its 2004 list, just ahead of Terry Fox and Pierre Trudeau.
No. 4, however, is a man whose name is less recognizable. Sir Frederick Banting won the 1923 Nobel Prize in medicine for his co-discovery of insulin, a hormone that regulates how our bodies use sugar and other nutrients. Why was this such a breakthrough? Until then, diabetes was one of the deadliest diseases on Earth. After being diagnosed, diabetic children rarely lived a year, and less than 20 percent of adults lived more than 10 years.
The discovery of insulin has saved hundreds of millions of lives and continues to keep diabetics alive and kicking. Today 11 million Canadians live with diabetes or prediabetes, with a new case being diagnosed every three minutes. No wonder Diabetes Awareness Month — November — is such a big deal.
The discovery of insulin was a game-changer, to be sure. But has it made all the health issues surrounding diabetes disappear? Not even close!
What is diabetes, anyway?
Diabetes is a chronic disease in which the body can’t make insulin or properly use the insulin it produces. This leads to high blood sugar levels, which can damage organs, blood vessels, and nerves.
There are two main types of diabetes. Type 1 usually develops in childhood or adolescence, so type 2 is the kind most adult men need to watch.

For healthy guys, digested food in the stomach breaks down into sugar or glucose sent to the bloodstream. Meanwhile, the pancreas makes insulin that helps move glucose from the blood into muscle cells to be used as fuel for energy right away or stored for later use. For guys with type 1 diabetes, the pancreas cannot produce insulin, so the glucose cannot get into the cells needed for energy. Glucose stays in the blood, which makes the blood sugar level very high and causes health problems. For guys with type 2 diabetes, the pancreas still makes insulin, but it doesn’t work in the body as it should. Blood sugar levels get too high, causing health problems that can be prevented with healthy eating and regular exercise.
What causes type 2 diabetes?
There is no single cause for type 2 diabetes, but several factors boost your risk of developing it. Here’s what increases diabetes risk:
- Being over 40 years of age.
- Being overweight, especially around the middle.
- Having high blood pressure.
- Having high cholesterol or other fats in the blood.
- Being of Aboriginal, Hispanic, Asian, South Asian, or African descent.
What are the symptoms of type 2 diabetes?
Many people who have type 2 diabetes show no symptoms. That’s why guys aged 40 and up should see their doctor about checking their blood-sugar levels through a quick and easy test.
When symptoms do occur, they can include the following:
- Unusual thirst
- Frequent urination
- Weight gain or loss
- Extreme fatigue or lack of energy
- Blurred vision
- Frequent or recurring infections
- Cuts and bruises that are slow to heal
- Tingling or numbness in the hands or feet
- Trouble getting or maintaining an erection
If you have any of these symptoms, contact your health-care provider ASAP.
