What is Diabetes?

Diabetes currently affects 246 million people worldwide and is expected to affect 380 million by 2025.¹ More than 2 million Canadians have diabetes. By the end of the decade, this number is expected to rise to 3 million. Even though diabetes affects nearly 4% of the world’s population², many people know very little about the disease.
There are 2 primary types of diabetes:
-
Type 1 diabetes occurs when your immune system destroys the beta cells in the pancreas that produce insulin. As a result, the body makes very little or no insulin of its own. People with type 1 diabetes must take insulin daily. Type 1 diabetes is sometimes called juvenile diabetes or insulin-dependent diabetes.
-
Type 2 diabetes occurs when the pancreas does not make enough insulin, or the body cannot properly use the insulin it does produce. Initially, changes in diet and activity levels may control blood glucose levels. As type 2 diabetes progresses pills and/or insulin may be added to control blood glucose. Eventually, the pancreas may stop producing insulin altogether. Type 2 diabetes can affect people at any age. In both men and women, excess weight increases the risk of developing type 2 diabetes.³
Hyperglycemia

Hyperglycemia, or high blood glucose, occurs when blood glucose rises above your recommended range. Your healthcare professional will determine the proper healthy blood glucose range for you.
High blood glucose can be caused by many things, including:
- Eating too much food
- Little or no physical activity
- Not taking medications
- Stress, infection or illness
- Bad or spoiled insulin
High blood glucose can cause serious problems and a major cause of long-term diabetes complications. Warning signs of high blood glucose include:
- Tiredness or fatigue
- Increased thirst
- Frequent urination
- Blurred vision
- Dry mouth or skin
- Slow-healing cuts and sores
- Unexplained weight loss
It is important to keep your blood glucose level within your target range. Checking your blood glucose often may help you avoid hyperglycemia. During illness your blood glucose levels can increase because of the hormones in the body that are helping you to get better. If you have type 1 diabetes you may need more insulin when you are sick, talk to your healthcare provider.
