Let’s talk numbers: the 8th edition of the Diabetes Atlas 2017 reports that over 350
million people between 20 and 79 years worldwide are estimated to have developed impaired
glucose tolerance (IGT). Translated, this estimate equates to more than every 14th
person worldwide with impaired glucose regulation after testing for an oral glucose
tolerance test (OGTT), routinely used for diagnosing type 2 diabetes. IGT occurs when
results are above the normal range (7.8 mmol/L (140.4 mg/dL) to 11.1 mmol/L (199.8 mg/dL)),
but not high enough to be classified as having diabetes. IGT, also called prediabetes,
carries a high risk for developing type 2 diabetes. Prediabetes is a term that covers
varying degrees of altered glucose metabolism.
