Signs and symptoms can include the following:
Sometimes a routine exam by an eye doctor or foot doctor will reveal diabetes. Diabetes affects the circulation to your feet and the tiny blood vessels in your eyes. If your eye doctor or your foot doctor suspects you have diabetes, he will recommend you see your regular physician for a blood sugar level test. The most common test is a fasting blood glucose test. After not eating for at least eight hours, usually overnight, your doctor will take a blood sample. The normal, non-diabetic range for blood glucose is 70 to 110 mg/dl. If your level is over 140 mg/dl, you may have diabetes.
See your doctor. Your doctor will perform tests to determine whether or not you have diabetes. If your blood sugar level is high, but not high enough to be considered diabetic, this is a condition called pre-diabetes. Your doctor will make recommendations to bring down your blood sugar level so that you can delay the development of Type 2 diabetes.
