“Managing T1D is walking on a knifes edge between DKA and Hypoglycemia by balancing blood glucose levels with insulin.”
An 18 month old’s peanut butter sandwich takes carb ratios, sensitivity factors, a finger prick and a 15 minute wait. Too little insulin heads toward DKA, coma and death. Too much means hypoglycemia. Parents do this math several times a day, forever, with rules of thumb that you “just pick” by feel. A pancreas does it for free.
