People with type 2 diabetes usually have a combination of problems: the pancreas does not produce enough insulin; and the body's fat and muscle cells are resistant to the insulin.

This means that insulin does not do its normal job of helping the cells to process glucose and make energy or store the energy for use later.

The cells are starved of energy as the glucose remains in the bloodstream. The glucose builds up in the bloodstream leading to what's known as a ‘high blood sugar’ or ‘high blood glucose’ level.
