Regular and safe physical activity is especially important for people with diabetes.

Blood Sugar and Exercise

The most common concern people have about exercise and diabetes is how to keep their blood sugar levels from getting too high or too low. Here are some general guidelines to follow:

  • Exercise at the same time every day, if possible. This will help you find out how exercise affects your blood sugar.
  • Check your blood sugar before exercising. If your blood sugar is less than 100 before you start to exercise, eat a carbohydrate snack. If your blood sugar is 250 or higher, don’t start exercising until your blood sugar level is under 250.
  • Exercise with a friend who knows that you have diabetes and knows how to help if your blood sugar gets too low.
  • Make sure you have ID with you that lets people know you have diabetes.
  • If you’re sick or have an infection, don’t exercise until you’re feeling better. Being sick affects your blood sugar.
