Post blood sugar test is one way to test and control diabetes. Both high and low blood sugar levels can be dangerous. Read on to learn more about the test and the reasons for high or low blood sugar. We’ll also look at the best strategies to reduce your blood sugar to successfully prevent or treat diabetes, says Denis.
What is a powdered sugar test?
The procedure is. The blood sugar test at the post is also called the blood glucose test at the post. It measures the sugar level after fasting for at least eight hours. Glucose is the main sugar in your bloodstream, and high levels after fasting can indicate diabetes, Dr. Slinkin said.
You can still drink water while you are fasting FBS before the test (unless your doctor says otherwise), but you should avoid drinking drinks such as coffee, tea, juice and soda. A health worker will take blood for a vein on your arm, which will be sent to a laboratory for analysis.
After a meal, your blood glucose levels usually rise within a few hours as you break down and absorb dietary carbohydrates. In healthy people, the pancreas will produce insulin to move glucose to and from the bloodstream. In this way, glucose levels will gradually drop after eating and remain low during fasting FBS. People with diabetes either do not have enough insulin to reduce blood glucose (type 1 diabetes mellitus) or their body cannot effectively use insulin (type 2 diabetes mellitus). In an on an empty stomach blood glucose test, diabetes mellitus patients will have blood sugar levels significantly higher than non-diabetics, which can lead to many health problems in the long term.
An on an empty stomach blood sugar test measures blood glucose levels after fasting for at least 8 hours. High blood glucose levels can indicate diabetes.
Why do doctors order it
An on an empty stomach blood glucose test is performed for diabetes mellitus and prediabetes. It also helps doctors control diabetes and determine if medications and dietary changes have an effect on the diet.
Blood glucose levels on an empty stomach are the lowest, as the effect of recent meals is minimal.
Your blood sugar level FBS on an empty stomach is often checked together with HbA1c (also known as glycated hemoglobin), which is a measure of your blood sugar level over the past three months. The more blood sugar you have, the more it will add to hemoglobin, increasing your HbA1c level.
Taken together, they provide more information than each test individually. For example, even if your blood sugar level is very high at one random point, it may have been mostly low during the last few months (low HbA1c). On the other hand, HBA1c may be higher, but glucose levels are currently lower.
