Type 1 diabetes: overview

In Australia, 1 in 700 children has type 1 diabetes.

Type 1 diabetes usually starts in childhood or adolescence — but it can begin at any age.

Type 1 diabetes usually runs in families, so if you have a close relative (a parent, brother or sister) with type 1 diabetes, you are more likely to develop it. 

The body makes little or no insulin if you have type 1 diabetes, which leads to high levels of glucose (a type of sugar) in the blood.

High blood glucose levels can cause a range of different symptoms, which may cause problems and complications over time if they are not controlled.

Read about the causes of type 1 diabetes, and how it is diagnosed and monitored.

Treatments for type 1 diabetes

While there is currently no cure for type 1 diabetes, it can be controlled by adopting a healthy lifestyle in addition to using injected insulin to control blood glucose levels.
