Identifying Type 2 Diabetes

Because high blood sugar levels (hyperglycemia) develop gradually in people with type 2 diabetes, there often are no symptoms in the early stages of the disease. Also, most symptoms of diabetes are not specific for the disease. The person may ignore them or may think they are caused by an illness or aging. As a result, the person with type 2 diabetes may have the disease for many years before he or she knows it.
