If you have type 1 diabetes or if you have type 2 diabetes and take insulin and/or diabetes pills, be sure to:
Check your blood sugar before and after physical activity. If you use insulin to manage your diabetes, work with your diabetes care team to learn how you might need to adjust the amount of insulin you use and/or discuss how you might want to change your meal plan to account for the amount and type of activity you plan to do. This is especially important to help you prevent low blood sugars during long periods (over 3 hours) of exercise.
- You may need to eat an extra snack when your insulin or diabetes pills are working the strongest or you are doing moderate to high levels of exercise for over 30 minutes.
- Be aware that moderate to high activity levels can lower your blood sugar right away or up to 24 hours after you have stopped being active.
- If you do not take insulin, plan to be active within an hour after eating your meals or snacks to prevent low blood sugars. If you have type 1 diabetes and your blood sugar is less than 120 before exercising, eat 15-30 grams of carbohydrate before you start exercising.
- If you have type 1 diabetes and your blood sugar is over 250, use a urine test strip to check your urine for ketones before you start exercising. Do
not exercise if ketones are moderate or high. Ketones are a certain type of chemical that forms in your blood when your body starts to break down fat to use for energy instead of glucose. This happens when you have high blood sugar levels and not enough insulin in your body. When the level of ketones in your blood gets too high, your kidneys help to remove it from your blood so it appears in your urine.
