A sure fire way to find out if you are a diabetic is to have a complete physical with your primary care physician; this should include blood work ( a hemoglobin A1C test should be done to test your average blood sugar for the month) Before you see the doctor you should consider keeping a diary of the food you eat, your symptoms, and when they occur. A symptom of hyperglycemia (high blood sugar) is excessive thirst and urination, your urine might be darker than usual and might smell sweet. A symptom of hypoglycemia (low blood sugar) could be head aches, light headedness, confusion, and unusual behavior, which could also be associated with hyperglycemia as well. And, any of these symptoms can be associated with any number of things so it is always a good idea to see a doctor rather than relying on the internet for advisement.
