You're welcome. I found this too.
Infection causes a stress response in the body by increasing the amount of certain hormones such as cortisol and adrenaline.
These hormones work against the action of insulin and, as a result, the body’s production of glucose increases, which results in
high blood sugar levels.
When your blood sugar is high, the white cells in your body are unable to “mop up” bacteria because they cannot move
around at their normal speed and do not reach the infection site quickly enough to engulf and kill the bacteria. In a person
who does not have diabetes, extra insulin is produced to counter these effects, but this is not possible for someone with diabe-
tes, and so hyperglycemia persists and ketoacidosis can occur.
