• Insulin is the hormone that 'unlocks' the cells in your body and allows the sugar (glucose) in your blood to be used for immediate energy needs, or stored away for later use.
• Blood glucose comes mainly from carbohydrates in the foods you eat. These are broken down in your digestive system and then transported by your blood stream around your body to be used as fuel for the energy we need in everyday life.
• Unless you have enough insulin, the glucose in your blood cannot be used efficiently, hence causing your blood glucose levels to rise.
• If left untreated, high blood glucose levels can cause long-term health problems. Being diagnosed with diabetes will give you the opportunity to make the necessary changes to your lifestyle, therefore enabling you to avoid some of the risks associated with diabetes.
