D Type I diabetes is an autoimmune disorder
Two forms of diabetes mellitus are now recognized.
Type I, or insulin dependent diabetes mellitus: It is an autoimmune disorder that results in the destruction of the insulin-secreting β cells of the pancreas. Treatment for these patients consists of insulin injections since they cannot produce insulin on their own.
Type II, or non-insulin dependent diabetes mellitus: This is the type of diabetes that most people suffer from. This form is due to the destruction of the receptors for insulin on cells. They generally have normal or even above-normal levels of insulin in their blood, but their cells have a reduced sensitivity to insulin. These people do not require insulin injections and can usually control their diabetes through diet and exercise.
