Diabetes can lead to serious complications and premature death, but people with diabetes can take steps to control the disease and lower the risk of complications.

Causes of Diabetes: Type 1
The cause of type 1 diabetes is the destruction of the insulin-producing beta cells of the
pancreas by a person's own immune system. These beta cells of the pancreas are the only cells in the body that make the hormone insulin that regulates blood glucose.
A combination of genetic and environmental factors put people at increased risk for type 1 diabetes. Researchers are working to identify these factors and to stop the autoimmune process that destroys the pancreas. Currently, there is no known way to prevent type 1 diabetes.
Type 1 diabetes can occur at any age, but it most often occurs in children and young adults. Type 1 diabetes has an acute onset, with children and adolescents usually able to pinpoint when their
diabetes symptoms began.

Type 1 diabetes accounts for 5 percent to 10 percent of all diagnosed cases of diabetes.
