Type 2 runs rampant on both sides of my family. I've had symptoms since I was a kid, and have been tested almost every year as an adult. However, my test results have always been in the healthy range, so I guess I'm not diabetic, at least not yet.
It's strange to read through the comments and see all the symptoms and recognize them in myself.
Granted, I think the only diagnostic tool most care providers in the USA look at is the A1C number. I've asked many questions over the years: could my symptoms be caused by something else, is it possible that A1C numbers might not be a reliable indicator for some people, and things like that. Basically get told not to worry about it.
Either way, I still get tested each year.
