Not type I diabetes (caused by destruction of beta-cells in the pancreas and a lack of insulin), but type II diabetes. Type II diabetes has nothing to do with a lack of insulin, it is generally considered to be caused by insulin resistance i.e. enough insulin is produced, but there is ‘resistance’ to its effects.
