Prevent or delay type 2 diabetes:
Healthy choices work best to delay or prevent type 2 diabetes. You may be given the following guidelines from your healthcare provider:
- Get regular physical activity. Adults should get at least 150 minutes (2.5 hours) of moderate physical activity every week. Spread the amount of activity over at least 3 days a week. Do not skip more than 2 days in a row. Children should get at least 60 minutes of moderate physical activity on most days of the week. Examples of moderate physical activity include brisk walking, running, and swimming. Do not sit for longer than 30 minutes at a time. Work with your healthcare provider to create a plan for physical activity.
- Lose weight if you are overweight. A weight loss of 7% of your body weight can help. Your healthcare provider can tell you what weight is healthy for you. He or she can help you create a weight loss plan.
- Eat healthy foods. Eat a variety of fruits and vegetables. Eat whole-grain foods more often. Choose dairy foods, meat, and other protein foods that are low in fat. Eat fewer sweets, such as candy, cookies, regular soda, and sweetened drinks. You can also decrease calories by eating smaller portion sizes. Work with your healthcare provider or dietitian to develop a meal plan that is right for you.
- Take medicine as directed. Your healthcare provider may give diabetes medicine if you are at high risk for diabetes. You may also need medicines for high blood pressure and high cholesterol.
- Follow up with your healthcare provider as directed. You will need to return every year to get tested for diabetes.
- Do not smoke. Do not use e-cigarettes or smokeless tobacco in place of cigarettes or to help you quit. They still contain nicotine. Ask your healthcare provider for information if you currently smoke and need help quitting.
- Start with small goals and work your way up. You may need to start with 3 days of physical activity. You can add a day after 3 weeks or so of activity. Make a goal of losing 5 pounds at first. Swap a piece of fruit for dessert or sweets. Start with 2 fruits in a week and increase it weekly. These are suggestions. Talk with healthcare providers about making a plan that is right for you.
Follow up with your doctor as directed:
If you do have prediabetes, you will need to return every year to get tested for diabetes. Write down your questions so you remember to ask them during your visits.
