T1D Risk

300K people are at increased risk of developing Stage 3 T1D1

People at risk icon

There are many
patients with
presymptomatic (Stage 1 and 2) T1D

More than 300,000 people in the United States are in the presymptomatic stages of type 1 diabetes. Beta-cell destruction begins months to years before the onset of T1D symptoms; those at increased risk may not be aware.1,2

The lifetime risk of developing Stage 3 T1D is up to 15x higher than the general population for any first-degree relatives of current T1D patients3,4

If both parents have T1D, the child’s risk is

*If the child was born before the mother turns 25 years old; if child was born after 25, risk is 1 in 100.4

A child’s risk is doubled if a parent developed Stage 3 T1D before age 11.4

Knowing what to look for and how T1D progresses in patients is the first step in the future of care
