Symptoms

Often, people with type 2 diabetes have few or no symptoms of the disease. Many people with type 2 diabetes don't even know they have it. For some people, feeling run down is their only type 2 diabetes symptom, which is so general that the diabetes may go unnoticed. Other people with type 2 diabetes may:
 
  • Feel thirsty
  • Urinate often
  • Lose weight
  • Get skin infections
  • Have blurred vision
  • Heal slowly from cuts and bruises.
     
It is important to tell your doctor right away if you experience any of these possible symptoms of type 2 diabetes.

Making a Diagnosis

If you are experiencing diabetes symptoms, medical tests can confirm if type 2 diabetes is causing your problems. A doctor can make a type 2 diabetes diagnosis by reviewing your symptoms and checking your blood glucose levels.
 
One test, called a fasting plasma glucose test, measures your blood glucose level after not eating or drinking (fasting) for at least 8 hours -- usually overnight. In another test, called the oral glucose tolerance test, your blood glucose is checked and then you drink a sugary beverage. Your blood glucose levels are then checked 1 hour, 2 hours, and 3 hours later. A diabetes diagnosis is confirmed after a repeat test on a different day.
