THE GLUCOSE TOLERANCE TEST

To test your body’s ability to handle sugar, your doctor will probably have you drink a bottle of glucose water that contains 75 grams of glucose. He will then check your blood sugar two hours later. This is called the glucose tolerance test. It gives you an idea of how well your pancreas can deal with a sugar load. If it is producing the right amount of insulin, you will have a normal blood sugar level after two hours. You could actually do this test at home. Simply drink a 20-ounce cola, wait a couple of hours, and then check your blood sugar level using a glucometer, or glucose monitor. You can borrow one from a friend who has diabetes or purchase one at almost all pharmacies. It’s not a perfect test, but it will give you an idea of how your pancreas is working.1

The results from a glucose tolerance test will be one of the following diagnoses:

Normal Fasting Glucose and Response: A person is said to have a normal glucose when the fasting glucose is <100. A normal response is when the 2-hour glucose level is less than or equal to 140 mg/dL.

Impaired Fasting Glucose When a person has a fasting (before meal) glucose equal to or greater than 100 mg/dL and less than 126 mg/dL, they are said to have impaired fasting glucose. This is considered a risk factor for developing diabetes in the future. A person with this diag- nosis is not labeled a diabetic, but they will probably be tested again in the near future.

Impaired Glucose Tolerance A person is said to have impaired glucose tolerance when the 2-hour glucose results from the oral glucose tolerance test are greater than or equal to 140 mg/dL but less than 200 mg/ dL. This is also considered a risk factor for developing diabetes in the future.

Diabetes A person has diabetes when the fasting glucose is above 125 or the oral glucose tolerance test shows the blood glucose level after 2 hours is equal to or more than 200 mg/dL. These results must be confirmed by a second test on another day.


Both Impaired Fasting Glucose and Impaired Glucose Tolerance diagnoses are associated with low HDL (good) cholesterol, high triglycerides, high blood pressure and obesity—especially abdominal or visceral obesity. Moreover, regarding both the Impaired Glucose Tolerance and Diabetes diagnoses, there has recently been discussion about lowering the upper value to 180 mg/dL. This would enable more people to be diagnosed with mild diabetes and allow earlier intervention and hopefully prevention of diabetic complications.
