Type 1 diabetes is a chronic (lifelong) disease that causes a person’s blood glucose (blood sugar) levels to become too high. In people with Type 1 diabetes, their bodies do not make hormones called insulin and glucagon to keep their blood sugar levels in a normal range.
Type 1 diabetes is diagnosed in ~18,000 children and teens under age 20 every year. It is most common in non-Hispanic white children and teens under age 20.
