Not a doc but a few buddies with "almost diabetes". Many times, overweight to obese is a trigger. Also, high fructose corn syrup is reported to mess up your endocrine system. 200 is way high. Did you get the A-1-C checked? This is a better indicator. You should get both checked.

On any medical, you should drink water all day and when you pee it should be the cleanest pee possible. Not saying this will avoid a diabetes flag, but it is better than submitting a dehydrated cup of dark yellow urine and causing the nurse to say "uh, what is this"

Good Luck
