Diabetes & Glucagon: Why Do Levels Rise?

[goingmad]

Why is it the case that glucagon levels actually rise during diabetes? This seems to be what's implied everywhere I look. What causes the rise? Is it more accurate to say that all the metabolic things that start happening with untreated diabetes is because of the drop in the insulin:glucagon ratio in general? Is it even the case that glucagon levels rise?
I'm so confused about this!
Thanks,

Try Wiki. They have a pretty good summary.
