Fasting Blood Sugar (Fasting Blood Glucose) • Hello Sehat

Definition

What is fasting blood sugar (fasting blood glucose)?

Blood glucose test serves to measure the level of sugar in the blood called glucose. Glucose comes from foods that contain carbohydrates which serve as a source of energy for the body. Insulin is a hormone that helps the body’s cells utilize glucose. Insulin is produced in the pancreas which is then released in the blood when glucose levels increase. Usually your glucose levels will increase slightly after you eat. This increase in glucose causes the pancreas to release insulin so that the sugar level in your blood is not high. Blood sugar levels that are too high can damage your eyes, kidneys and blood vessels.

A fasting blood sugar test will be done after you have fasted for 8 hours.

When should I go on fasting blood sugar (fasting blood glucose)?

Your doctor will recommend that you do this test if you experience symptoms of diabetes. Doctors may also advise patients with diabetes to do this test. This test will also be done if you:

  • urinating more often than usual
  • blurred vision
  • confused and rambled
  • passed out
  • convulsions (for the first time)

Precautions & warnings

What should I know before undergoing fasting blood sugar (fasting blood glucose)?

The level of glucose in the urine can also be measured. Diabetics have glucose in the urine they excrete. If there is glucose in the urine, then the level of glucose in the blood must be very high. In this case, a urine glucose test may not be done to diagnose or monitor diabetes. If you have diabetes, you can take your blood glucose level at home.

Process

What should I do before undergoing fasting blood sugar (fasting blood glucose)?

This test is one of the tests performed to diagnose glucose levels in the blood. You are required to fast for 8 hours before your blood sample is drawn. If you are positive for diabetes, you may be asked to wait a while before you are given the morning insulin medication. Then you will have a series of tests that do not require you to fast.

How is the process of fasting blood sugar (fasting blood glucose)?

The medical personnel in charge of drawing your blood will take the following steps:

  • wrap an elastic belt around your upper arm to stop blood flow. This makes the blood vessel under the bundle enlarge making it easier to insert the needle into the vessel
  • clean the area to be injected with alcohol
  • inject a needle into a vein. More than one needle may be required.
  • Insert the tube into the syringe to fill it with blood
  • untie the knot from your arm when enough blood is drawn
  • attaching gauze or cotton to the injection site, after the injection is complete
  • apply pressure to the area and then put a bandage on

What should I do after undergoing fasting blood sugar (fasting blood glucose)?

An elastic band is wrapped around your upper arm and will feel tight. You may not feel anything when you get the injection, or you may feel like you are stung or pinched. You can remove the bandage and cotton from the area after 20 to 30 minutes. Then you will be informed of the test results. Make sure you follow your doctor’s directions.

Explanation of the Test Results

What do my test results mean?

A normal test result known as the “reference range” serves as a guide only. This reference range is usually different in each laboratory. Your test results will usually follow the reference range guidelines of the laboratory in question.

Normal glucose levels are usually less than or equal to 100 milligrams per deciliter (mg / dL) (5.6 millimoles per liter or mmol / L).

High yield

You may be diabetes positive.

Other conditions that can also cause glucose levels to increase such as:

  • severe stress
  • heart attack
  • stroke
  • Cushing’s syndrome
  • corticosteroid-like drugs
  • excess production of growth hormone (acromegaly)

Low yield

Glucose levels less than 40 mg / dL (2.2 mmol / L) in women or less than 50 mg / dL (2.8 mmol / L) in men followed by symptoms of hypoglycemia can lead to insulinoma, a tumor that produces insufficient amounts of insulin. normal.

Low glucose levels can also result from:

  • Addison’s disease
  • decreased levels of thyroid hormone (hypothyroidism)
  • tumors of the pituitary gland
  • liver disease, eg cirrhosis
  • kidney failure
  • malnutrition or feeding problems, eg anorexia
  • medicines to treat diabetes
