T1D Risk

300K people are at increased risk of clinical T1D1


People at risk icon

There are many
patients with
presymptomatic 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.1-3


The lifetime risk of developing T1D is 15x higher than the general population for any first-degree relatives of current T1D patients4-6

*If the child was born before mother turns 25 years old; if child was born after 25, risk is 1 in 100.

A child’s risk is doubled if a parent developed T1D before age 11.6


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