Part of managing your diabetes is checking your blood sugar often. Ask your doctor how often you should check and what your blood sugar levels should be. Checking your blood and then treating high blood sugar early will help you avoid problems associated with hyperglycemia.
You can often lower your blood sugar level by exercising. However, if your blood sugar is above 240 mg/dl, check your urine for ketones. If you have ketones, do not exercise.
Exercising when ketones are present may make your blood sugar level go even higher. You'll need to work with your doctor to find the safest way for you to lower your blood sugar level.
