* These values are the borderline cases of mild high blood sugar
and can be recommended for further investigations tests by the
doctor so that the person with such condition should take necessary
precaution to control it in time.

If your
physician orders a glucose tolerance test, it will be scheduled in
the morning after you have had three days of good food intake so
that your body can handle sugar optimally. Your will be asked not to
eat breakfast that morning so that your first blood sample will
reflect your fasting glucose level. next you will be given a
beverage or test meal containing glucose to drink or eat. On some
occasions glucose is administered intravenously. At various hourly
intervals after you have taken the glucose, blood samples will be
taken and the glucose level of your blood will be measured.
This test is usually not used by physicians during periods of long
dietary restriction, illness, or disability or without the three day
good food intake preparation.
If you do not have diabetes or impaired glucose tolerance, the
resulting readings, plotted on a graph, the graph will show a normal
pattern. If you do have diabetes, the graph will show that
your blood glucose level rose and kept rising and did not even begin
to drop by the end of the test. If you have impaired glucose
tolerance, the graph will look much like the nondiabetics graph, but
it will indicate higher blood sugar concentrations with normal
fasting or end-of-test levels. The levels will fall between the
range of the nondiabetic and the diabetic on the graph. The term
impaired glucose tolerance refers to the condition in which the
fasting plasma glucose level is between normal and diabetic levels.
This term is used instead of the term borderline, chemical or latent
diabetes.
If a glucose tolerance test reveals that you have impaired glucose
tolerance, your doctor may recommend that you have further tests.
Also, because people with impaired glucose tolerance are more likely
to develop diabetes, and because at this stage diabetes is
preventable, your doctor may advise you to lose weight, cut your
intake of simple sugars, exercise more, and avoid cardiovascular
risk factors, including high blood pressure, smoking, and high
cholesterol levels.
