Observing Saturday's Dexcom graph below, you'll see an ugly pattern in the first 18 hours. This is indicative of the previous 3 days' patterns as well. No tactic we attempted proved to be a match for the havoc this illness was wreaking on her blood sugar. Her first dose of antibiotic was at noon. We did nothing different that afternoon, diabetes-wise.
The fever was gone by mid-day Sunday and so was the lethargy of illness.
I know the medical community is increasingly wary of prescribing antibiotics, recognizing that their overuse can cause problems on both individual and global levels. These are important concerns. But sometimes there's an actual infection and an antibiotic is needed. Had an antibiotic been started on Wednesday, we wouldn't have spent 3 days beating our heads against the wall fighting unfightable high blood sugars. And she wouldn't have spent so much time on the couch instead of at school, or out in the spring air.
