Question from Zion, Illinois, USA:

Why is it that children with type 1 experience a drop in their blood sugar so fast with exercise while non-diabetic kids don't?

Answer:

As blood glucose falls, and it does in children who don’t have diabetes, the insulin level goes to nearly unmeasurably low, not zero ever, but very low and the glucose stops falling. Injected insulin is always there and likely is too high as the glucose falls, so it keeps falling. The delicate balance of insulin on board and in the blood is very difficult when the insulin is injected. We suggest using food to temper the extra effect of the insulin that lowers the glucose after exercise.
