Type 1 diabetes

Facts about type 1 diabetes

  • There is currently no cure for T1D, and its exact cause isn’t known.1
  • T1D is a chronic autoimmune condition in which the pancreas produces little or no insulin by itself.1
  • People can be diagnosed with T1D at any age.1
  • It’s been found that 90% of people living with T1D have no family history of the condition, but having a family history does put people at higher risk of developing T1D.2
  • T1D was once known as juvenile diabetes or insulin-dependent diabetes.3 (This is where JDRF gets its name, as JDRF is an acronym for Juvenile Diabetes Research Foundation.)
