GLUCOSE TOLERANCE TEST
It is a common investigation technique used for estimating the amount of blood glucose levels in a patient and how well it is getting utilized by the body.
Diabetes is a condition in which there are issues with the metabolism of glucose in the body. High blood sugar level is a characteristic feature of Diabetes be it type – 1, type – 2 or gestational diabetes.
This test is particularly popular in pregnant women who develop Diabetes in pregnancy and need proper management for a safe childbirth. Type – 2 Diabetes is also called as maturity onset Diabetes and is a result of many contributing factors because of which proper functioning of the insulin hormone in the body is affected.
Type – 1 Diabetes occurs during the juvenile phase of life and is an autoimmune disease in which the body itself destroys the beta cells of the pancreas which produce insulin. There is a continuous dearth of insulin in this condition and such patients require direct insulin to manage blood sugar levels and other symptoms like excessive urination (polyuria), excessive thirst (polydypsia) and excessive hunger (polyphagia).
WHO CAN TAKE THIS TEST?
Any person suspected of having raised blood sugar levels can take this test. Pregnant women are advised to take this test at 24 – 28 weeks of pregnancy.
Continue taking a normal and balanced diet in the days before the test.
Consult your doctor if you are taking any kind of medicines like beta blockers which may interfere with the results of the test.
Take only water orally, eight hours prior to the test.
Hold urine as you may be asked to take a urine sample.
The test is conducted over a period of one, two to three hours depending upon the doctor's prescription.
DURING THE TEST
At the beginning of the test a blood and urine sample is taken.
The patient is then given a concentrated sugar solution to drink at the beginning of the test. The solution may contain 50 g or 75 g sugar in it. Accordingly, the blood sample is repeated after one hour or twice every two hours.
With 100 g sugar, the test continues for three hours and blood sample is taken every hour for three hours.
Normal glucose level findings stand at:-
For 50 g, one hour test – normal blood sugar levels are equal or less than 140 mg/dl.
For a two hour 75 g test – Fasting levels 60-100 mg/dL ; one-hour levels less than 200 mg/dL; two-hours less than 140 mg/dL
For a 100-gram test: Fasting levels less than 95 mg/dL ; one-hour levels less than 180 mg/dL; two hours less than 155 mg/dL; three hours, less than 140 mg/dL
What if you have a positive glucose tolerance test?
A positive test result shows that you need constant medical attention. Especially among pregnant females, it becomes very essential to keep the blood glucose levels under control as a high blood sugar level will adversely affect the growth of the fetus.
Is it necessary to take anti – diabetic medicines with a positive glucose tolerance test?
It is not necessary that you need to take anti – diabetic medicines if you have a positive glucose tolerance test. Many a times, slight modifications in diet and lifestyle can help the patient and normal blood glucose levels can be easily achieved.
