The most common form of diabetes is type 2 diabetes. About 90 to 95 percent of people with diabetes have type 2. This form of diabetes is associated with older age, obesity, family history of diabetes, previous history of gestational diabetes, physical inactivity, and ethnicity. About 80 percent of people with type 2 diabetes are overweight.
Type 2 diabetes is increasingly being diagnosed in children and adolescents. However, nationally representative data on prevalence of type 2 diabetes in youth are not available.
When type 2 diabetes is diagnosed, the pancreas is usually producing enough insulin, but for unknown reasons, the body cannot use the insulin effectively, a condition called insulin resistance. After several years, insulin production decreases. The result is the same as for type 1 diabetes-glucose builds up in the blood and the body cannot make efficient use of its main source of fuel.
The symptoms of type 2 diabetes develop gradually. Their onset is not as sudden as in type 1 diabetes. Symptoms may include fatigue or nausea, frequent urination, unusual thirst, weight loss, blurred vision, frequent infections, and slow healing of wounds or sores. Some people have no symptoms.
What if I have type 2 diabetes?
Type 2 is the type of diabetes most people get as adults after the age of 40. But you can also get this kind of diabetes at a younger age.
Healthy eating, exercise, and losing weight may help you lower your blood glucose (also called blood sugar) when you find out you have type 2 diabetes. If these treatments do not work, you may need one or more types of diabetes medication to lower your blood glucose. After a few more years, you may need to take insulin shots because your body is not making enough insulin.
You, your doctor, and your diabetes teacher should always find the best diabetes treatment plan for you.
