What is type 1 diabetes?

Type 1 diabetes is a chronic, progressive autoimmune condition

That means it needs to be managed for life and it gets worse over time in stages. You can think of an autoimmune disease like a programming error in the immune system. The immune system is programmed to protect people from harmful threats. But with autoimmune type 1 diabetes, the immune system mistakenly thinks healthy cells, called beta cells, are a harmful threat and attacks them.

Screen for Type 1’s mission is to equip individuals and families with the tools and the knowledge required to take action and get screened for type 1 diabetes, before it becomes an emergency.
