Type 1 diabetes is an auto-immune condition in which the immune system is activated to destroy the cells in the pancreas which produce insulin. We do not know what causes this auto-immune reaction. Type 1 diabetes is not linked to modifiable lifestyle factors. There is no cure and it cannot be prevented.
Type 1 diabetes, once known as juvenile diabetes or insulin-dependent diabetes, is a chronic condition in which the pancreas produces little or no insulin. Insulin is a hormone needed to allow sugar (glucose) to enter cells to produce energy.

The role of insulin
Insulin is a hormone that comes from a gland situated behind and below the stomach (pancreas).
- The pancreas secretes insulin into the bloodstream.
- Insulin circulates, allowing sugar to enter your cells.
- Insulin lowers the amount of sugar in your bloodstream.
- As your blood sugar level drops, so does the secretion of insulin from your pancreas.
At present Type 1 diabetes has no cure. Treatment focuses on managing blood sugar levels with insulin, diet and lifestyle to prevent complications.
Type 1 diabetes is managed with insulin injections several times a day or the use of an insulin pump. While your lifestyle choices didn't cause type 1 diabetes, the choices you make now can reduce the impact of diabetes-related complications.
