Type 2 diabetes is diagnosed in a number of ways. These include a fasting glucose of > or = 126 mg/dL, a hemoglobin a1c of 6.5% or greater, or elevated glucose on an oral glucose tolerance test. In addition, a random glucose of >200 is suggestive of diabetes.
However, there are a number of signs and symptoms that suggest type 2 diabetes and should make you consider getting a blood test. These include excessive thirst, frequent urination, blurred vision, numbness or tingling of extremities, weight gain and fatigue. Other possible symptoms include erectile dysfunction in men and irregular periods in women.
