The body needs insulin during exercise. Therefore, it is not suggested that you stop the pump unless the
exercise is for a short amount of time (one hour or less). If you need to remove the pump for more than one
hour, refer to the If you remove your pump section in The basics chapter.
If you do an exercise that on average lowers your blood glucose, you can use the temporary basal rate feature.
You can use this feature to lower the amount of insulin delivered and reduce the risk of hypoglycemia. You
may also choose to change your basal rate pattern for the days you exercise.
It takes a period of time to determine how much to adjust your basal rate during exercise. Record your blood
glucose before, during and after exercise to figure the proper reduction in your basal rate. Record any
carbohydrates that you have eaten during the exercise period. There is no magic formula that will tell you
just what to do. You have to test often to figure out the basal rate that you need during exercise.
