Every child should exercise at least 60 minutes a day, including children with diabetes. While exercise is great for daily overall health, research has shown that it can improve overall diabetes management. Exercise increases insulin sensitivity, which means it helps your body use insulin more efficiently.
Your glucose levels during and after exercise will depend on several things:
- Your glucose level before exercise.
- The intensity and duration of the exercise you are doing.
- The amount of insulin you take.
Check glucose levels every hour or as needed. If it’s greater than 250, correct for the high and check for ketones. If you have moderate or large ketones, do not exercise. If your glucose level is less than 80 before exercise, treat the low and then wait until it has increased above 80 to begin exercising.
Check your glucose level every 30 minutes. A continuous glucose monitor, or CGM, can be a helpful tool to monitor glucose levels during exercise.
Check your glucose level. Remember that exercise can cause lows many hours later and often overnight.
Everyone is different. Once you figure out how your body reacts to exercise, you’ll be able to better predict the steps you’ll need to take to enjoy your workouts and stay safe.
