Type 2 Diabetes

There are some things that you cannot change that increase your chances of getting type 2 diabetes:

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. The American Diabetes Association estimates that over 40 million Americans age 40 to 74 have prediabetes.² 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 than whites for type 2 diabetes.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 diabetes or reduce your chances of developing complications from diabetes:

• Lose weight. Your risk for 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 type 2 diabetes. People who do moderate exercise for at least 30 minutes on most or all days of the week have a lower risk of developing type 2 diabetes.⁶
• 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 developing type 2 diabetes.^{7, 8, 9} Eating whole grains, nuts, and vegetables can decrease your risk.¹⁰
• Quit smoking. This change may reduce your chance of having complications from diabetes.
• 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.¹¹
• Get treatment if you have high blood pressure (hypertension). People who have blood pressure levels above 140/90 millimeters of mercury (mm Hg) are at greater risk for type 2 diabetes than people who have blood pressure below 140/90.⁴
• Get treatment if you have high cholesterol. People who have high-density lipoprotein (HDL) cholesterol levels of 35 milligrams per deciliter (mg/dL) or less, or triglyceride levels of 250 mg/dL or more are at higher risk of developing complications from type 2 diabetes.⁴

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

• Polycystic ovary syndrome (PCOS), a hormone imbalance that interferes with normal ovulation.
• Metabolic syndrome, a group of abnormal physical findings related to the body's metabolism.

If you are concerned about diabetes, you can take a test to determine your risk of getting the disease. If you are at risk, you can discuss with your doctor how to make healthy changes in your life. If you want, your doctor can refer you to health professionals who are trained to help you make your own easy-to-follow plan for eating and exercising. No matter how and when you start, it is important to remember that even small changes can lower your chances of developing diabetes.
