Type 1 diabetes is a serious, lifelong condition where your blood glucose level is too high because your body can't make a hormone called insulin.
Around 10 per cent of people living with diabetes in the UK have Type 1 diabetes. It’s the most common type of diabetes in childhood but it can develop at any age.
What causes Type 1 diabetes?
We don’t know exactly what causes Type 1 diabetes. But we do know it’s not caused by your lifestyle – it’s an autoimmune condition. This means that your body attacks and destroys the cells that make insulin, so the body stops making it. We need insulin to help move glucose out of our blood and into our cells, so we can use it for energy. Without insulin, blood glucose levels get too high. That’s why everyone with Type 1 diabetes uses insulin to treat their diabetes.
