Type 1 Diabetes

Type 1 Diabetes
This handout is about type 1 diabetes. Type
1 diabetes means that the body no longer
makes insulin. It is caused when the body’s
immune system attacks and destroys the
cells in the pancreas that make insulin.

Insulin is a hormone made in the pancreas. It
is needed to move glucose into the cells.
Insulin opens the cell walls and allows
glucose to enter. Once inside the cells,
glucose is used for energy. Glucose is the
fuel that your body needs to function well.
Without insulin, glucose builds up in your
blood. This can cause symptoms of high
blood sugar and cause long-term problems.

Risk Factors
The main risk factor is having a family
member with type 1 diabetes. It is more
common in whites than nonwhites. It occurs
most often in young people but can occur at
any age. Of all people with diabetes, about
5% have type 1 diabetes. The cause of this
disease is not clear.
