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.
