People with type 2 diabetes produce insulin, but either do not make enough insulin or their bodies do not efficiently use the insulin they make. People with type 2 diabetes may be able to control their condition by losing weight through diet and exercise. They may also need to inject insulin or take medicine along with continuing to follow a healthy eating pattern and being physically active on a regular basis. Type 2 diabetes was known as noninsulin-dependent diabetes or adult-onset diabetes and is the most common form of diabetes. Children and adolescents who are overweight may also be at risk to develop type 2 diabetes.
