Exercise While Using Insulin
Exercise may lower your body's need for insulin during and for some time after physical activity. Exercise may also speed up the effect of insulin, especially if the exercise involves the area of the injection site (i.e., you give yourself an injection in the thigh and go jogging.) However, exercise is good for everyone — especially if you have diabetes. Before you begin an exercise program
- Have a medical check up. This is especially important if you are 35 or older. It is also important if you have any health problems besides diabetes.
- Talk with your healthcare team about an exercise plan that is right for you.

Staying safe while exercising
Below are some tips to help make sure you get the most out of your exercise:
- Start slowly. Five or 10 minutes a day is a good beginning if you have been inactive.
- Wear comfortable, supportive shoes and cotton socks. Check your feet after exercise for any signs of poor shoe fit or injury.
- Wear diabetes identification jewelry.
- Check your blood sugar before and after exercise. This is especially important for anyone who takes insulin, a sulfonylurea or a meglitinide. These medicines may create risk for low blood sugar.
- Carry something to eat that contains glucose. Use it to prevent or treat low blood sugar if needed.
- Stretch and warm up at the beginning of your activity. This helps prevent injuries.
- Drink more liquids that contain no calories, like water, when exercising.
- If you have leg or chest pains during exercise, stop exercising and call your doctor.
- Avoid exercising if your fasting blood sugar is above 300 mg/dL or under 70 mg/dL.
