FAQS for type 1 diabetes

Why have I got type 1 diabetes?

We don’t yet know the exact cause of type 1 diabetes but we do know it has a strong family link. However it can only occur when something, like an infection triggers the immune system to destroy the insulin-making cells in the pancreas. While the cause of type 1 diabetes has nothing to do with lifestyle, a healthy lifestyle is very important to manage diabetes.

Can type 1 diabetes be prevented or cured?

There is a great deal of research happening around the world, but at this stage nothing can prevent or cure type 1 diabetes.
