Type 2 diabetes is usually diagnosed using the Glycated hemoglobin (A1C) test. The A1C test is a blood test that indicates your average blood sugar levels for the past few months. If the A1C test isn’t available your doctor may recommend other tests including random blood sugar test, fasting blood sugar test or oral glucose tolerance test. The symptoms of Type 2 diabetes due to high blood sugar may include increased thirst, increased hunger, dry mouth, frequent urination, unexplained weight loss, blurred vision, etc. If you experience any of the Type 2 diabetes symptoms you should contact your healthcare provider. Other symptoms of Type 2 diabetes may include; slow-healing of sores, itching of the skin, frequent yeast infections, erectile dysfunction, unexplained weight loss or recent weight gain.
