Type 2 Diabetes Early Warning Signs

Although 24 million people have been diagnosed with diabetes, it's estimated that an additional 5.7 million people have the disease but don't know it. Type 2 diabetes doesn't always have clear symptoms, and often isn't diagnosed until found accidentally during a physical or check-up. Is the condition really symptomless or are there early warning signs that can sound the alarm?

Signs and Symptoms of Diabetes

  • Feeling excessively tired
  • Unquenchable thirst
  • Frequent urination
  • Numbness and/or tingling in feet or hands
  • Changes in eyesight, such as blurry vision
  • Unexpected weight loss
  • Increase in infections or wounds that won't heal
  • Breath that smells fruity

If you, or someone you know, has one or more of these symptoms, make an appointment to see your doctor.
