When does fasting blood sugar or FBS test?

Glucose or glucose is the primary source of energy for the body's cells and the only source of energy for the brain and the nervous system. Using glucose, or the same blood glucose as an energy source, depends on insulin, a hormone produced by the pancreas. Insulin facilitates the transfer of glucose to the body's cells and directs the liver to store excess body energy as fat or short-term storage. Usually after a meal, blood glucose increases slightly. And by releasing insulin from the blood by the pancreas, it is responded to this increase, which causes glucose to be absorbed by the body's cells and reduces its blood levels.

If glucose levels drop immediately after exercise, the other hormone secretes a liver called glucagon to increase blood sugar levels. If this balance collapses and the blood sugar level is still higher due to inappropriate pancreatic soles to produce insulin or defense of the body relative to insulin, the body will try to eliminate excess uric acid in its attempt to solve this problem. Made

People who can not produce enough insulin, often due to antibodies to the immune system against these cells, will be affected by type 1 diabetes. Individuals who are resistant to insulin-producing pancreas may develop pre-diabetes or type 2 diabetes. Some women may have high blood sugar and have gestational diabetes.

When is there a need for a fasting blood glucose test?
When a person is over the age of 45.
High Risk of Diabetes
The presence of symptoms suggests high blood sugar or low blood sugar
At the time of diabetes and to evaluate the treatment process
Who is at high risk for diabetes and who needs to have an FBS test?
Overweight people without mobility
Having a family history
Women with a history of gestational diabetes or birth of babies over 4kg
Women with polycystic ovary syndrome
People with high blood pressure or taking low blood pressure medications
Low cholesterol level (less than 35 mg / dl or 0.90 mmol / lit)
High triglyceride levels (greater than 250 mg / dl or 82.2 mmol / lit)
History of cardiovascular disease
HbA1C equal to or above 5.7%
What preparations are required for FBS testing?
This test is the easiest way to evaluate diabetes, which is why blood sugar values ​​are tested in the morning. In most cases, you should stay alive all night long before doing this test by avoiding any eating or drinking fast. Of course, drinking water after an evening promise does not cause any problems before performing the blood test. This fasting should be at least 8 hours.

If you have overnight shift, it is best for you to have at least one full 6-hour sleep snap before doing this and have everyday activities after waking up. You should avoid any kind of eating or drinking except water after waking up and before taking blood.

In some people with diabetes, fasting blood sugar can be taken at any time of the day, fasting, after a meal. It is also likely that you should avoid taking some medications before testing, as there may be an impact on the test results. Avoid arbitrary discontinuation of medication without consulting your doctor.

Interpreting the results of fasting blood glucose testing
The normal range of fasting blood glucose in most laboratory centers is 77 to 99 mg / dl or 3.9 to 5.5 mM / L.
The fasting blood glucose level is from 100 to 125 mg / dl or 5.5 to 6.9 mmol / lit, a pre-diabetic state.
A fasting glucose level of 126 mg / dl or 7 mmol / liter or earlier can mean diabetes.
These results should be repeated again for confirmation.
Fasting blood glucose can be higher than usual in cases where:
In conditions of possible pre-diabetes, which can lead to diabetes.
At the time of diabetes
Diabetics are likely to be diagnosed and insulin or any other drug has not been used to manage diabetic conditions. A diet related to diabetic conditions has not been respected.
If you have liver and kidney disease
Pancreatic inflammation
The body has been severely affected by stress, disease, infection, or damage.
Using some medications, such as steroids such as prednisolone, can increase your blood sugar.
The possibility of a fasting blood sugar lower than normal range may have occurred for the following reasons:
You have diabetes, and a dose of a diabetic drug or any other drug that has controlled these conditions is higher than the prescribed dose. Diabetes has been in control of the drug and in addition, no sugar has been consumed.
Thyroid glands, adrenal glands, pituitary glands do not function properly.
There is a risk of liver disease in such situations.
The probability of poor food intake
Failure to enter sufficient quantities of substances needed to the body
