Because this risk of pump therapy is well known, the means for avoiding it are also well understood. Part of your education as a new pump user includes emphasis on frequent blood testing . This allows you to notice any unexplained problems with control as quickly as possible. You're also taught exactly what to do anytime your blood glucose is behaving oddly, so that small problems get dealt with promptly, preventing their turning into big problems like diabetic ketoacidosis. Relatively few pump wearers are prone to developing infections at the infusion site.
Infections are usually mild but, if ignored, can become more serious.
Infections can almost always be prevented by following a good skin cleansing routine and, for a few, the use of a topical antibiotic. That is why skin care and site inspection techniques are part of the education of every new pump user. Both the potential for more rapid development of DKA and the risk for skin infections at the infusion site are serious issues. However, they are almost totally avoidable. For experienced pump users who receive the necessary training and apply what they know, the actual rates of these problems is extremely low.
