Yes.

I suspect that you might find something useful in newsgroup:

alt.support.hypoglycemia

ever hear the key analogy?

Imagine that the cells of the body are little furnaces or car engines.

if a furnace the door is locked and can't get any fuel, sugar or
glucose.

if a car engine, the gas cap is locked and you can't put any fuel or
sugar/glucose in.

Insulin is the key that unlocks the furnace door or engines gas cap.

Type 1s don't make the keys, insulin, so we inject it.

Type twos make broken keys.  Some work some don't.  some type twos try
to make a lot of keys in order to have enough that will open the doors
or fuel caps, but end up making too many and as a result end up
opening too many doors or gas caps taking too much fuel out of the
fuel system (the blood stream) and cause the cells to burn off the
fuel too fast (low blood sugar)

Now the food we eat is what the body turns into the fuel, glucose.

so a type 2 will eat the proper food to make the right amount of
glucose/fuel and sometimes take oral meds to help make better fuel or
help make better keys.  Different meds do different jobs.

would that help your child understand the process?

That's really good, Cindy. I just emailed it to my kids, who have a bunch
of Munchkins running around.
