What is Diabetes?
Diabetes is a disease where the pancreas cannot produce a hormone called insulin, or cannot properly use the insulin it produces, or a combination of both. This causes the level of sugar in the blood to rise, which can damage organs, blood vessels, and nerves.
A condition in which a person’s blood glucose level is above normal, but not high enough to be considered diabetes. Prediabetes has no symptoms and can only be diagnosed with a blood test. It is also called impaired glucose tolerance or impaired fasting glucose. People with prediabetes are at high risk of developing type 2 diabetes and cardiovascular disease and should take steps to lower these risks.
Type 1 Diabetes
An autoimmune disease that occurs when the pancreas no longer produces any insulin or produces very little insulin. Type 1 diabetes usually develops in childhood or adolescence, however it can develop later in adulthood, and affects approximately 10% of people with diabetes. There is no cure. It is treated with lifelong insulin injections and careful attention to diet and physical activity. Formerly called insulin-dependent diabetes or juvenile diabetes.
Type 2 Diabetes
A disease that occurs when the pancreas does not produce enough insulin to meet the body’s needs and/or the body is unable to respond properly to the actions of insulin (insulin resistance). Type 2 diabetes usually occurs later in life (although it can occur in younger people) and affects approximately 90% of people with diabetes. There is no cure. It is treated with careful attention to diet and exercise and usually also diabetes pills (oral antihyperglycemic agents) and/or insulin. Formerly called non-insulin-dependent diabetes or adult-onset diabetes.
Diabetes that is first diagnosed or first develops during pregnancy. It affects 2% to 4% of all pregnancies. Blood glucose levels usually return to normal following delivery. Both mother and child are at higher risk of developing type 2 diabetes later in life.
