Is type 2 diabetes the same as prediabetes?

No: Pre-diabetes is a state before diabetes. There are 3 tests to diagnose pre or full diabetes. The most common one is the measurement of fasting blood sugar. Normal is < 100, pre-diabetes is 100-125, anything over 126 is indicative of diabetes. You need two positive tests to diagnose diabetes or pre-diabetes. Not enough room here to describe the other two tests (hba1c and ogtt).

Not quite: Prediabetes means u have high blood sugar, but not yet high enough to be called type ii diabetes. U r headed in that direction though. Eliminate grains and sugar from diet. If on a medication like metformin, be sure to let your doc know about diet changes asap. If on a station drug like lipitor, (atorvastatin) these increase risk for diabetes. Diet is biggest factor. Eat low carb. Avoid soda.
