 Previous studies have shown that a person with type 1 diabetes is less likely to suffer the long term microvascular complications of diabetes eye, kidney and nerve damage if they strive to achieve as near normal a blood glucose as possible. Unfortunately the tighter the blood glucose control is, the more likely the subject is to suffer episodes of hypoglycemia. Hypoglycemia is often the aspect of diabetes management most feared by people with diabetes and may cause more anxiety than the threat of advanced complications.
