If there is still insulin in the syringe, changing the infusion set is usually a wise decision. In order to prevent running out of insulin, the syringe should be filled every 2-3 days as the set is changed. Table 5 summarizes some other possible pump problems. With leaks in the infusion set, a bead of insulin may be noted or the odor of insulin may be detected. There are several options for altering the insulin dose with exercise and experience is usually the best teacher to see which works.

It is generally not as necessary to eat and then perform on a full stomach. Some people start the reduction 30 minutes before the exercise and continue it for 30 minutes after the exercise is over. In general, if the pump is to be disconnected for more than two hours, a blood sugar must be done. If the blood sugar is rising, it is easy to reconnect, take a small bolus, and again disconnect. People must determine what works best for them.
