Type 2 Diabetes Center

Type 2 diabetes is a metabolic disorder resulting from the body's inability to make enough, or to properly use, insulin. It used to be called non-insulin-dependent diabetes mellitus (NIDDM).

Without adequate production or use of insulin, the body cannot move blood sugar into the cells. It is a chronic disease that has no known cure. It is the most common type of diabetes.

The exact cause of type 2 diabetes is unknown. However, there does appear to be a genetic factor which causes it to run in families. And, although a person can inherit a tendency to develop type 2 diabetes, it usually takes another factor, such as obesity, to bring on the disease.

People with type 2 diabetes often develop the disease after age 45, but are not aware they have diabetes until severe symptoms occur, or they are treated for one of its serious complications.

Type 2 diabetes is more prevalent among African American, Hispanic/Latino American, and Native Americans. Type 2 diabetes is nearing epidemic proportions, due to an increased number of older Americans, and a greater prevalence of obesity and a sedentary lifestyle.

Of the 20.8 million Americans with diabetes, 90 percent to 95 percent have type 2 diabetes. Of these, half are unaware they have the disease.
