impaired glucose tolerance

Abbreviation: IGT
Altered glucose metabolism in which fasting blood sugars are less than 126 mg/dl, and blood sugar levels are over 140 mg/dl but less than 200 mg/dl 2 hr after drinking 75 g of glucose.

CAUTION!

Having either impaired glucose tolerance or impaired fasting glucose predisposes patients to diabetes mellitus, heart attack, stroke, and early death. Patients with abnormal glucose metabolism ought to receive professional dietary counseling. They should also begin a program of regular physical exercise.
