Risk Factors for Type 2 Diabetes

Your chances of developing type 2 diabetes depend on a combination of risk factors such as your genes and lifestyle. Although you can’t change risk factors such as family history, age, or ethnicity, you can change lifestyle risk factors around eating, physical activity, and weight. These lifestyle changes can affect your chances of developing type 2 diabetes.

Read about risk factors for type 2 diabetes below and see which ones apply to you. Taking action on the factors you can change can help you delay or prevent type 2 diabetes.
