What is T1?

Also known as juvenile diabetes, it is most common in children but can be diagnosed at any age – approximately 10% of people with diabetes are Type 1. 

It is an autoimmune disease that permanently destroys beta cells (insulin-producing cells) in the pancreas, meaning that the body can no longer produce insulin. The cause of the beta cell destruction remains unclear. 


Insulin is a protein that comes from the pancreas which is located in the mid-abdomen. It allows glucose (sugar) to enter our cells to then be used as energy for the body, because our body needs glucose to operate. 

In a healthy person, insulin is automatically released by the pancreas on a regular basis, and also when a person eats to counter the glucose that was consumed. In a person with Type 1 diabetes the body cannot use glucose properly because there is no insulin being produced, so levels of glucose in the blood rise to dangerous levels. 

Because the pancreas of a person with Type 1 can no longer make insulin, they require regular blood tests (finger pricks) and insulin delivery (injections or insulin pump) to manage their diabetes.
