When does type 1 diabetes start?

Type 1 diabetes usually starts between 4 and 6 years of age and 10 and 14 years of age, with approximately half of children diagnosed before the age of 10. However, type 1 diabetes can occur at any age.

Type 1 diabetes most commonly starts in children between the ages of 9 and 14. However, it can affect anyone, at any age.
