Traditionally, particularly before modern treatment and improvements in diabetes care in recent years, people with type 1 diabetes tended to live shorter lives, by up to twenty years on average. However, with improvements in diabetes care over recent years, people with type 1 diabetes are enjoying longer lives than ever. If you have type 1 diabetes, it is recommended that you maintain control over your blood glucose levels so as to prolong your life and avoid complications that could potentially be fatal. Keeping your blood sugar levels within recommended ranges will help to reduce the chance of complications and increase your life expectancy. It is recommended that you maintain a healthy lifestyle, including a well-balanced diet and regular physical activity to keep your blood pressure and cholesterol at healthy levels and to maintain good blood circulation.
