Type 1 diabetes occurs when the pancreas does not produce insulin – the hormone that helps the body control the level of sugar in the blood (1). Without insulin, sugar builds up in the blood (1). Type 1 diabetes is not caused by eating too much sugar, nor is it preventable (1). To treat type 1 diabetes, insulin is given in through a prefilled insulin pen, needle or pump (1).
About 90% of people with diabetes have type 2 diabetes which occurs whenthe pancreas does not produce enough insulin; or insulin is produced, but it is not properly used by the body (2). As a result, sugar builds up in the blood. Type 2 diabetes is a life-long disease that gets worse over time, but complications can be prevented or delayed with good care and management (2). Insulin therapy may be used to help the body control its blood sugar levels (2). Also, other medications, physical activity and healthy eating help the body in controlling blood sugar levels (2).

Why is this important to know?
Nine million Canadians are living with diabetes or prediabetes (when a person’s blood sugar is higher than normal, but not high enough to be seen as type 2 diabetes) (3). Diabetes is common in older adults— about 1 in 6 males and 1 in 7 females aged 65 and over in Canada have diabetes (4). Diabetes can lead to heart disease, kidney disease, vision loss, loss of erection (impotence) and nerve damage (loss of feeling) (3).
