Prediabetes - What Increases Your Risk

The risk factors for prediabetes are similar to the risk factors for type 2 diabetes. Most people who get type 2 diabetes had prediabetes first.

Risk factors that you cannot control include:

  • Family history. If you have a parent, brother, or sister who has type 2 diabetes, you have a greater chance of developing the disease.
  • Age. The risk for getting prediabetes and type 2 diabetes increases with age. And the number of children being diagnosed with type 2 diabetes is increasing. Usually, children who get type 2 diabetes have a family history of the disease, are overweight, and are physically inactive.3
  • Race and ethnicity. African Americans, Hispanics, Native Americans, Asian Americans, and Pacific Islanders are at higher risk for type 2 diabetes than whites.4
  • History of gestational diabetes or having a baby weighing more than 9 lb (4 kg). Women who have had gestational diabetes or who have had a large baby are at higher risk for developing type 2 diabetes later in life.4
  • Low birth weight. People who weighed less than 5.5 lb (2.5 kg) at birth are more likely to develop type 2 diabetes later in life.5

There are some things you can do to reduce your chances of getting prediabetes and diabetes:

  • Lose weight. Your risk for prediabetes and type 2 diabetes increases as your weight (or body mass index, BMI) increases. Your risk also increases if most of your body fat is in your belly area. Reaching and staying at a healthy body weight can reduce your risk.
  • Get more exercise. The less you exercise, the greater your risk of developing prediabetes and type 2 diabetes.6 Try to do moderate activity at least 2½ hours a week. Or try to do vigorous activity at least 1¼ hours a week. It's fine to be active in blocks of 10 minutes or more throughout your day and week.7 For more information, see the topic Fitness.
  • Eat foods that are good for you. Eating a lot of sugary foods, red meat, soft drinks, and fast food can increase your risk of getting prediabetes and type 2 diabetes. Eating whole grains, nuts, and vegetables can decrease your risk.8
  • Get treatment if you have prediabetes. If your fasting blood sugar levels are in the range from 100 mg/dL to 125 mg/dL, you are at increased risk for developing type 2 diabetes.9
  • Quit smoking. This change may reduce your chance of developing complications from diabetes.

Other conditions that put you at risk for prediabetes and type 2 diabetes-and that are also linked with obesity and a lack of physical activity-include:
