A glucose tolerance test is used for examining someone’s capacity to handle a glucose load. Thus, the test checks whether a person can absorb normal levels of glucose or not. It also helps in diagnosing type 1 diabetes, type 2 diabetes, and gestational diabetes mellitus. It is a blood test and involves the repeated withdrawal of blood samples over a period of time (usually two hours).
The glucose tolerance test measures the amount or levels of glucose that remain in your blood after observing a fast and then consuming glucose at frequent intervals. Glucose levels in the blood are commonly measured in milligrams per deciliter, or mg/dl.
No severe or harmful side effects are associated with the glucose tolerance test. However, after the intake of glucose, one might feel nauseous, sweaty, lightheaded, or even experience shortness of breath and fainting.

A glucose tolerance test can be performed if you have a dry mouth or are experiencing symptoms such as dizziness, an increased thirst, frequent urination, etc. You can also go for the glucose tolerance test if you are diabetic or obese. This test is usually performed in conjunction with other diagnostic procedures to confirm the diagnosis.
The frequency of the glucose tolerance test depends on several factors, such as body weight, heart disease history, high blood pressure, gestational diabetes, female sex hormone imbalances, genetic diabetes problems, inactivity, polycystic ovary disease, etc. If you are above the age of 45, you may be advised to go for the glucose tolerance test after every three years. Asymptomatic children who are above the age of 10 and experience any of the two risk factors listed above should also go for the same at least once every three years.
You should not consume anything 8 to 14 hours before your glucose tolerance test. However, you can stay a bit hydrated. Do inform your doctor about any drugs you are intaking, history of previous ailments, etc, before your glucose tolerance test.

Before you consume the drink, your blood sample will be taken. Another blood sample will be taken once an hour has passed after the intake of the glucose.
You must remain in the clinic until the test has been completed and not go home, otherwise the test would be considered as invalid.
