Type 1 Diabetes Facts and Tips


  • Type 1 diabetes can also be called insulin-dependent diabetes because people with type 1 must take insulin in order to live.
  • Type 1 diabetes used to be called juvenile diabetes because it was diagnosed mainly in children. However, that name is no longer accurate because children are increasingly developing another type of diabetes—type 2 diabetes. Also, it is possible for adults to be diagnosed as type 1, so the name “juvenile diabetes” isn’t accurate.
  • Researchers aren’t exactly sure what causes type 1 diabetes, although they have some clues, including genetics and environmental triggers.
  • Researchers have noticed that more cases of type 1 diabetes are diagnosed in northern climates, leading them to suggest that environmental triggers play a role in the development of type 1. Specifically, viral infections (which happen more often in colder northern climates where people are in close proximity) may trigger type 1.
  • Type 1 diabetes is far less common than type 2: about 90% of people with diabetes have type 2.
  • With tight blood glucose control, you can avoid many of the short- and long-term complications associated with type 1 diabetes, including foot problems and nerve pain.
  • Exercise is an important part of keeping diabetes under control.
  • Many famous people have type 1 diabetes, including: Jay Cutler (quarterback for the Chicago Bears), Billie Jean King, Ron Santo (Chicago Cubs player), Halle Berry, Mary Tyler Moore, and Nick Jonas.
