Which is the correct term to use, pre-diabetes or prediabetes?
The American Diabetes Association and National Institutes of Health both initially used the term “pre-diabetes” (with a hyphen).  The NIH is now adopting the no-hyphen version. However, either is considered correct and pre-diabetes and prediabetes can be used interchangeably.
No matter what you call it, pre-diabetes is a serious metabolic condition and if it is not treated aggressively can lead to the development of type 2 diabetes.
