Pre-diabetes is a condition that typically develops before type 2 diabetes. The body’s blood glucose levels are higher than normal – but not high enough for the person to be diagnosed with diabetes, according to the American Diabetes Association.

The association estimates there are about 79 million Americans with pre-diabetes. If you are diagnosed with pre-diabetes, you can avoid the actual diabetes diagnosis by eating right, exercising and managing your weight.
