How does insulin help control blood sugar, what's the process?

I have half a pancreas due to car accident, I been treated as a pre-diabetic, I know in the beginning I injected insulin, it's been 10 years now and I've avoided it, I have seen my doctor and due to the fact that I don't have neither type, (Type l/TYPE 2) I just monitor my sugar, it's come to the point that I can't control my bad habits, maybe I should inject insulin if my blood sugar is high, but I'm scared! How will it really help me, for me not to see it as a bad thing, but a good thing! Or are there other alternatives???

Cells need glucose to function. Think of your cells as being "locked." Insulin is the key that "unlocks" the cell so glucose can enter and be used. Without insulin, your cells cannot use the glucose, and it builds up in your blood. This is hyperglycemia.

That being said, if you only have half a pancreas, your insulin-producing capabilities are compromised. The pancreatic beta cells will have to work twice as hard to keep your blood glucose levels at a normal level, and could eventually stop functioning. This would leave you essentially as a Type I patient, and you'd need insulin.

There really is no alternative at that point. The best thing you can do at this point is to avoid spikes in blood sugar...basically live as a Type 2 diabetic would and try to control it with diet and excercise. Yes, avoid those bad habits! :-)

Good luck!
