We got a nasty infection this weekend in an old pump site. It developed into a painful lump that needed to be drained by the doctor and now our little girl to go through a round of medication to treat the bugs that caused it.
We poke and prick and inject so often with our daily diabetes regimen that I think we forget how much we put the body at risk to germs. We continually break the body's natural body to infection - the skin - with many many needles.
Kids (and adults) with diabetes have a lowered immune system and are more susceptible to infection. And overprescription of antibiotics has spawned superbugs like MRSA (Methicillin-resistant Staphylococcus aureus) that don't respond to treatment with penicillin or other beta-lactam antibiotics. Fortunately there are other families of antibiotics and sulfa drugs that can knock these types of things out - if treated early enough.
So the moral of the story is wash, wash, wash your hands. Use clean, sterile lancets and needles. And be sure to disinfect sites with alcohol wipes whenever you can!
