Early identification through screening may allow for earlier conversations with your healthcare provider
Talking to your doctor about screening is an important step if you have a family history of type 1 diabetes

Understanding Your Family Risk

Type 1 diabetes has a genetic component. If a parent, sibling, or child has type 1 diabetes, your own risk is significantly elevated—up to 15 times higher than someone without a family history of the condition.

What Early Screening Involves

Early detection of type 1 diabetes is possible through a blood test, before insulin therapy becomes necessary. This screening can identify autoimmune markers or changes in blood sugar that suggest type 1 diabetes may develop.

Next Steps: Talk to Your Doctor

If you have a family history of type 1 diabetes, consider speaking with your healthcare provider about screening options. They can help you understand your individual risk and determine whether testing makes sense for you or your family members.

Learning more about screening and your family's health history empowers you to take an active role in your health and that of your loved ones.
