The guiding principles for treating diabetes are early detection and prevention of complications. The glucose tolerance test is used for diagnosis. The WHO has proposed a change in the original GTT. In the modified GTT, 75g of glucose is given orally after checking the fasting levels in blood. Two hours after giving the glucose load, the blood glucose is checked. The diagnosis may be made as follows:
Category
Fasting glucose
After 2 hrs glucose
Non diabetic
< 110mg/dl
< 140mg/dl
Diabetic
< 140mg/dl
> 200mg/dl
Impaired glucose tolerance (IGT)
120-140mg/dl
140-200mg/dl
Gestational diabetes
120-140mg/dl
> 180mg/dl
Persons with impaired glucose tolerance tend to progress to diabetes at a rate four times that of normal persons.
