Yes! According to the American Diabetes Association, 5.7 million of the 23.6 million Americans with diabetes have not been diagnosed. The onset of type 2 diabetic symptoms is usually gradual. Those symptoms include feeling tired or ill, frequent urination (especially at night), unusual thirst, weight loss, blurred vision, frequent infections and slow healing of sores. If you have any of these symptoms, seek testing immediately. Since some people do not have any symptoms initially, you should also be tested if you have any of the major risk factors, which include obesity, lack of exercise, a close relative with diabetes, high blood pressure or cholesterol level and giving birth to a baby that weighs more than nine pounds. You are also at elevated risk if you are over 45 or are of African American, American Indian, Alaska Native, Asian and Pacific Islander American or Latino/Hispanic descent.
