Related to impaired glucose tolerance: Impaired fasting glucose

im·pair·ed glu·cose tol·er·ance

excessive levels (110-126 mg/dL) of blood glucose developing after a carbohydrate-rich meal or test dosage of glucose (usually 75 g). Not necessarily diagnostic for diabetes mellitus.

impaired glucose tolerance (IGT)

[imperd′]
Etymology: L, impejorare, to make worse; Gk, glykys, sweet; L, tolerare, to endure
a condition in which fasting plasma glucose levels are higher than normal but lower than those diagnostic of diabetes mellitus. In some patients this represents a stage in the natural history of diabetes, but in some people IGT either does not progress or ends, and glucose tolerance reverts to normal. Also called impaired prediabetes. See also diabetes mellitus.

im·pair·ed glu·cose tol·er·ance

(IGT) (im-pārd glūkōs tolĕr-ăns)
A disordered state in which a patient does not process glucose properly but such activity does not confirm a diagnosis of diabetes mellitus.

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.
