[edit intro]

Impaired Glucose Tolerance (IGT) is a pre-diabetic state of dysglycemia, that is associated with insulin resistance and increased risk of cardiovascular pathology. IGT may precede Diabetes mellitus type 2 by many years. IGT is also a risk factor for mortality.[1]

### Criteria[edit]

According to the criteria of the World Health Organization and the American Diabetes Association, impaired glucose tolerance is defined as[2][3]:

* two-hour glucose levels of 140 to 199 mg per dL (7.8 to 11.0 mmol) on the 75-g oral glucose tolerance test.

## Treatment[edit]

It is possible to reverse pre-diabetic states with improved diet and exercise.
