Type 2 Diabetes - Prevention
Many people have prediabetes before they have type 2 diabetes. If you're concerned about your risk, talk with your doctor. He or she will order tests to check your blood sugar levels. If you have prediabetes, you should be tested for type 2 diabetes every year. To learn more, see the topic Prediabetes.
You can take steps to prevent type 2 diabetes. Even small changes can make a difference, and it is never too late to start making healthier choices.
Stay at a healthy weight
A healthy weight is one that is right for your body type and height
and is based on your
body mass index (BMI) and the size of your waist (waist circumference). Losing just 7% of your body weight can help reduce
your risk for type 2 diabetes.1 If you
are age 20 or older, use the
Interactive Tool: Is Your BMI Increasing Your Health Risks? to check
your BMI. To use the tool, you'll need to know your height, weight, and waist circumference.
Do activities that raise your
heart rate. Try to do
moderate activity at least 2½ hours a week. Or try to
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.
include resistance exercises in your exercise program.2 Resistance exercises can include
activities like weight lifting or even yard work.
Walking groups or programs where you use a
pedometer to count the number of steps you take in a day are great ways to
start exercising and to stay motivated.

Eat healthy foods
Review the dietary guidelines for good health, which are good for everyone, including people who have prediabetes or type 2 diabetes.
Take medicine if you need it
If exercise, eating healthy foods, and being at a healthy weight don't help lower your blood sugar, you may need to take medicine. For people who have prediabetes, the medicine metformin can help prevent type 2 diabetes.
