Diabetes is a chronic disease that occurs when the pancreas does not produce enough insulin or when the body does not effectively use the insulin that produces. This results in an increased concentration of glucose in the blood (hyperglycemia).

Type 1 diabetes (formerly known as insulin-dependent diabetes or juvenile diabetes) is characterized by insufficient production of insulin.

The type 2 diabetes (formerly called non-insulin dependent diabetes or adult onset diabetes) results from the inadequate use of insulin by the body. It is often the result of a weight and physical inactivity excess.

Gestational diabetes is hyperglycemia which is detected during pregnancy.
