Type 2 diabetes is entirely different kettle of fish. The problem with type 2 diabetics is not that they can't make insulin, it's that the body inhibits the activity of the insulin.

    Type 2 diabetes used to be called non-insulin-dependent diabetes. The most common type of diabetes, nine out often cases of diabetes are type 2. It usually occurs in people over 45 and overweight, among other factors.  

    In fact, 90% of type 2 diabetics are obese when they contract the disease. This is because obesity increases insulin resistance. It also contributes to many health problems, including heart and blood vessel disease. When obese people with Type 2 diabetes lose weight, they often experience a lowering of their blood glucose levels and are then able to decrease their insulin or oral diabetes medications. 

When you have type 2 diabetes, either your body does not make enough insulin or your body still makes insulin but can't use it properly. Once again, it's worth repeating that without enough insulin, your body cannot move blood sugar into the cells so sugar builds up in the bloodstream. High blood levels of sugar can cause problems. 

Medical experts do not know the exact cause of type 2 diabetes. They do know type 2 diabetes runs in families. A person can inherit a tendency to get type 2 diabetes. But it usually takes another factor such as obesity to bring on the disease. This is not seen in type 1 diabetes where 90% of the cases reported haven't got a history of diabetes.
