People with diabetes are at risk for all of the long-term complications of diabetes. Some people get none, while others have multiple symptoms. Keeping blood glucose as close to normal as possible reduces the risk of developing complications.

There are three categories of complications: small vessel, large vessel and the nervous system. Small vessel problems occur in the kidneys and the eyes, large vessel problems occur in the legs, feet and heart. Problems of the nervous system can occur in many places; including the feet, legs, hands and also the stomach.

Keeping your blood glucose levels near normal will help prevent or delay these complications. Every improvement in blood glucose control helps in preventing complications.
