Re: 180 blood sugar
Well, a couple of things could be going on. You didn't say how old you are, but T2 is a disease of both weight and age, along with heredity. Being overweight definitely predisposes someone to it, but if you've got a strong family history of it, then you might develop it as you get older. That's why I said it's important to find out now, so that you can do everything possible to minimize its potential impact on you.
On the other hand, if you're not overweight, it's possible you are developing either T1 or T1.5. Both are auto-immune illnesses, but T1.5 develops much more slowly than T1. If you've recently had some sort of viral infection, then you might suspect T1 or T1.5. The way to test for those is to have your doctor do a c-peptide and GAD antibody test along with the fasting bloodwork.
And sometimes it's just a mystery as to why we develop T2. I know it's easy for me to say this (being a 24-year veteran of the D wars), but really...it's not the end of the world. The end of the world would be not knowing and therefore developing complications because you weren't diagnosed soon enough! I've seen that happen to too many people, and it always makes me angry at the doctors who just don't take T2, especially, seriously enough.
Okay...so you've got a couple of weeks to psych yourself up before that doctor's appointment. Take some deep breaths, do some relaxation exercises like deep breathing, meditation, etc., and know that whatever happens, you are a strong person and you will be okay.
And do come back and let us know how your appointment goes.
