Frequently Asked Questions

2. What is the difference between type 1 and type 2 diabetes?

Type 1 diabetes, which used to be called called juvenile diabetes or insulin-dependent diabetes, develops most often in young people. However, type 1 diabetes can also develop in adults. With this form of diabetes, your body no longer makes insulin or doesn’t make enough insulin because your immune system has attacked and destroyed the insulin-producing cells. About 5 to 10 percent of people with diabetes have type 1 diabetes.

To survive, people with type 1 diabetes must have insulin delivered by injection or a pump. Learn more about type 1 diabetes here.

Type 2 diabetes, which used to be called adult-onset diabetes or non insulin-dependent diabetes, is the most common form of diabetes. Although people can develop type 2 diabetes at any age -- even during childhood -- type 2 diabetes develops most often in middle-aged and older people.

Type 2 diabetes usually begins with insulin resistance—a condition that occurs when fat, muscle, and liver cells do not use insulin to carry glucose into the body’s cells to use for energy. As a result, the body needs more insulin to help glucose enter cells. At first, the pancreas keeps up with the added demand by making more insulin. Over time, the pancreas doesn’t make enough insulin when blood sugar levels increase, such as after meals. If your pancreas can no longer make enough insulin, you will need to treat your type 2 diabetes.
