Prevention

Healthy lifestyle choices can help prevent type 2 diabetes, and that's true even if you have biological relatives living with diabetes. If you've received a diagnosis of prediabetes, lifestyle changes may slow or stop the progression to diabetes.

A healthy lifestyle includes:

• Eating healthy foods. Choose foods lower in fat and calories and higher in fiber. Focus on fruits, vegetables and whole grains.
• Getting active. Aim for 150 or more minutes a week of moderate to vigorous aerobic activity, such as a brisk walk, bicycling, running or swimming.
• Losing weight. Losing a modest amount of weight and keeping it off can delay the progression from prediabetes to type 2 diabetes. If you have prediabetes, losing 7% to 10% of your body weight can reduce the risk of diabetes.
• Avoiding inactivity for long periods. Sitting still for long periods can increase your risk of type 2 diabetes. Try to get up every 30 minutes and move around for at least a few minutes.

For people with prediabetes, metformin (Fortamet, Glumetza, others), an oral diabetes medication, may be prescribed to reduce the risk of type 2 diabetes. This is usually prescribed for older adults who are obese and unable to lower blood sugar levels with lifestyle changes.
