Symptoms, Conditions and Diagnosis

Avoid complications by learning about diabetes

The United States Centers for Disease Control and Prevention estimates that nearly 26 million people have diabetes. More than 6 million of these people don't know they have the disease.

Symptoms for Type 1 & Type 2 diabetes

  • Frequent urination
  • Unusual thirst
  • Extreme hunger
  • Unusual weight loss
  • Extreme fatigue
  • Irritability

Other symptoms of Type 2 diabetes include:

  • Frequent infections
  • Blurred vision
  • Cuts or bruises that are slow to heal
  • Tingling or numbness in the hands or feet
  • Recurring infections of the skin, gums or bladder

The ADA recommends that all adults who are overweight and age 45 or older be screened for diabetes. A doctor may also recommend screening for adults younger than 45 who are overweight and also have one or more risk factors, such as:

  • A family history of diabetes
  • Belonging to an ethnic group that has high rates of diabetes, such as African Americans, Hispanics or American Indians
  • High blood pressure or hyperlipidemia—an excess of cholesterol or other fatty substances in the blood
  • Have a history of gestational diabetes, or have given birth to a baby weighing more than nine pounds
