Many people have diabetes but don't know it. That's why the American Diabetes Association (ADA) recommends that most adults begin diabetes screening at age 35. The ADA advises diabetes screening before age 35 for those who are overweight and have additional risk factors for prediabetes or type 2 diabetes.

Testing for diabetes also should take place for anyone who has early symptoms of diabetes. But those symptoms aren't always easy to notice. In fact, symptoms can develop so slowly that people may have type 2 diabetes for years before they're diagnosed with the disease.

If you notice the following symptoms, make an appointment to get care:

• Being very thirsty.
• Urinating often.
• Being much more tired than usual.
• Having blurry vision.
• Losing weight without trying.

Recognizing possible diabetes symptoms can lead to early diagnosis and treatment. That can help prevent complications of diabetes and lead to a lifetime of better health.
