Notice How Activity Affects Blood Glucose
Physical activity is important when you have diabetes. But you need
to keep an eye on your blood glucose level. Check often if you have
been active for longer than usual, or if the activity was unplanned.
Make it a habit to check your blood glucose before being active. Check
again several hours later (blood glucose may decrease for a few hours
after activity). Use your log book to write down how activity affected
your numbers. If you take insulin, you may be able to adjust your dose
before a planned activity. This can help prevent low blood glucose. Talk
to your health care provider to learn more.
