Type 1 diabetes occurs when the body fails to produce any insulin and insulin injections are required for life. It cannot be prevented.

The cause of Type 1 is unknown but it is thought to be an auto-immune process. In effect, the body produces antibodies to the pancreas which damage it and prevent the production of insulin.

Type 1 affects between 5-15% of all people with diabetes and usually starts below the age of 40.

It is always treated with insulin injections. There are many different types and regimens. If you are on insulin, you should discuss the most appropriate one for you with your diabetes care team.

A healthy diet and regular exercise also play a significant part in the good management of Type 1 diabetes.
