Illness influences blood sugar. I have known parents tell me they knew their son/ daughter was going to be ill the week before a cold or flu because of the change in their child’s glucose levels. Parents were worried about the glucose changes and came into the pharmacy to discuss this with me. The following week the child would take ill, it was as if the virus or bacterium was manipulating the hosts body to increase sugar levels.

It is important for the diabetic patient to rest if they feel ill, please note exercise makes ketoacidosis worse.
