I get this question a lot. The way to find out if you have diabetes is by an easy, blood test. The very best way to do this is by making an appointment with your physician. While there are more tests to find out if you have Type 1 Diabetes, which is more rare, this test is where to start.
Many people tell me they are too afraid to go to the doctor or their insurance doesn't cover much. There are lab services that offer testing at their location without a doctors referral. One of them is HealthLabs.com. I do urge you to go to your physician to get tested and talk about symptoms you might be having. Often people have no symptoms. I do make a small referral if you use Healthlabs.
