Pre-diabetes is a condition in which blood glucose levels are higher than normal, although not high enough to be diagnosed with type 2 diabetes. There are two pre-diabetes conditions:
• Impaired glucose tolerance (IGT) - blood glucose levels are higher than normal but not high enough to be classified as diabetes.
• Impaired fasting glucose (IFG) - blood glucose levels are escalated in the fasting state but not high enough to be classified as diabetes.
