How Long After Glucose Test Can I Eat?
There are a lot of precautions to be taken care of before you can get a glucose test done such as maintaining a particular diet or fasting for a couple of hours. But there are no such limitations after the test is complete. There are different sets of instructions and rules for different kinds of tests.
|Kind of test||After how long can you eat||For how long do you fast Before the test|
|Gestational Glucose Tolerance Test||Immediately after the test is done.||You can drink water but cannot eat anything for at least for a period of 8 hours.|
|Blood sugar test||As soon as the test is done||Fast for a period of two hours before the test.|
In the gestational glucose tolerance test, doctors advise you to bring along some snacks, because the fasting that has to be done before the test makes you tired. This test is taken when a woman is 24 to 28 weeks pregnant. Blood sugar tests are taken to check if you are diabetic or not. If you are from a family that has a history of diabetes, you are advised to take this test. In this type of test, you are supposed to wait after having a meal because taking a test as soon as food will give you an increased blood sugar count. It might raise a false alarm.
Why Should You Wait for So Long to Eat After a Glucose Test?
As most of the glucose tests require you to fast at least for a period of 6 to 8 hours before you can give your sample, you are advised to eat something immediately after the test, because otherwise, your sugar levels will drop further. It would be nice if you do not eat anything extremely sweet, or drink just caffeine such as tea or coffee. Any solid food can be consumed.
During the waiting process of a 1-hour test and a three-hour test, you will be asked to drink a sugary liquid. You are not supposed to take anything else. But in the end, you have no restrictions on your diet.
You cannot eat anything, strictly for a period of 4 hours before the test because it interferes with your test results. It would not give you accurate results. But after the test, you are free to eat anything that you want, at any time that you want. If possible, eat more than you usually do for your body to balance and get back the energy it lost while fasting before the sample was taken.
You might feel dizzy or even faint if your diet after the test is not proper. Food rich in protein such as chicken, fish, milk, or yogurt should be taken to bring energy to your body.
If you have heart-related diseases, high blood pressure, or if you are an extremely overweight person, you are supposed to take a glucose test. If a test is taken as early as possible, complications can be predicted and required measures can be taken without it turning to serious health issues. There are no after-effects for a glucose test. The most that can happen is, you might experience pain in the area the needle was injected but even that will go away in a few hours. A glucose test is nothing to be scared about but it is very imminent in predicting complications which helps us to stay safe.
