Fasting Blood Sugar Levels
Fasting, as the name suggests, means refraining from eating of drinking any liquids other than water for eight hours. It is used as a test for diabetes.
After fasting, a carbohydrate metabolism test is conducted which measures blood glucose levels.
Glucagon during fasting
When fasting the hormone glucagon is stimulated and this increases plasma glucose levels in the body.
If a patient doesn’t have diabetes, their body will produce insulin to rebalance the increased glucose levels.
However people with diabetes either don’t produce enough insulin to rebalance their blood sugar (typically in type 1 diabetes) or their body is not able to use the insulin effectively enough (typical of type 2 diabetes).
Consequently when blood glucose levels are tested, people with diabetes will have blood sugar levels significantly higher than people who do not have diabetes.
What is the fasting blood sugar test used for?
The fasting blood sugar test is also used to test the effectiveness of different medication or dietary changes on people already diagnosed as diabetic.
Fasting blood sugar levels are measured by taking a blood test after a period of fasting, usually of 8 hours without food. Typically, fasting blood glucose levels are taken in the morning before any breakfast is eaten. When having your fasting blood glucose levels taken, you should not have any drinks apart from water during the period of fasting.
A fasting blood glucose test can be useful to see how well the body is able to manage blood sugar levels in the absence of food. When we do not eat for several hours, the body will release glucose into the blood via the liver and, following this, the body’s insulin should help to stabilise blood glucose levels.
A fasting blood glucose test therefore shows:
- Whether the body is able to bring down the raise in blood glucose levels from the previous meal
- How effectively the body copes with its own release of glucose
The target for fasting blood glucose levels are the same as the targets for before meal readings.
- For adults with diabetes, the target level is between 4 and 7 mmol/l
- For children with diabetes, the target level is between 4 and 8 mmol/l
However, some people may be set individual targets, by their doctor, that differ to the above levels.
Fasting blood glucose tests for people with type 2 diabetes are useful for showing how well your body’s insulin responds to periods without food, such as overnight.
In type 1 diabetes, fasting blood glucose levels help to show whether your long term insulin, also known as background insulin, is set at the right dose. If you are in any doubt, Your healthcare team can help you to understand the levels you are getting and suggest any dosage changes.

If you experience symptoms of severe increased thirst, frequent urination, unexplained weight loss, increased hunger, tingling of your hands or feet — your doctor may run a test for diabetes.
According to the Centers for Disease Control and Prevention, some 29 million children and adults in the U. S., or over 9% of the population, have diabetes today. Yet, millions of Americans are unaware that they have diabetes, because there may be no warning signs.
To confirm the diagnosis of type 2 diabetes, your doctor will order a fasting plasma glucose test or a casual plasma glucose.
Diabetes and the Fasting Plasma Glucose Test
The fasting plasma glucose test (FPG) is the preferred method for diagnosing diabetes, because it is easy to do, convenient, and less expensive than other tests, according to the American Diabetes Association.
How Do I Prepare for the Blood Glucose Test?
Before taking the blood glucose test, you will not be allowed to eat anything for at least eight hours.
What Happens During the Blood Glucose Test?
During a blood glucose test, blood will be drawn and sent to a lab for analysis.
What Do the Results of the Blood Glucose Test Mean?
Normal fasting blood glucose — or blood sugar — is between 70 and 100 milligrams per deciliter or mg/dL for people who do not have diabetes. The standard diagnosis of diabetes is made when two separate blood tests show that your fasting blood glucose level is greater than or equal to 126 mg/dL.
However, if you have normal fasting blood sugar, but you have risk factors for diabetes or symptoms of diabetes, your doctor may decide to do a glucose tolerance test (see below) to be sure that you do not have diabetes.
Some people have a normal fasting blood sugar reading, but their blood sugar rapidly rises as they eat. These people may have impaired glucose tolerance. If their blood sugar levels are high enough, they may be diagnosed with diabetes.
The Casual Plasma Glucose Test for Diabetes
The casual plasma glucose test is another method of diagnosing diabetes. During the test, blood sugar is tested without regard to the time since the person’s last meal. You are not required to abstain from eating prior to the test.
A glucose level greater than 200 mg/dL may indicate diabetes, especially if the test is repeated at a later time and shows similar results.
The Oral Glucose Tolerance Test for Diabetes
The oral glucose tolerance test is yet another method used to detect diabetes, but it is usually only done during pregnancy to diagnose gestational diabetes or for someone who is suspected of having type 2 diabetes yet has a normal fasting glucose level. It can also be performed to diagnose prediabetes.
Diabetes and the Hemoglobin A1c Test
The hemoglobin A1c test (also called the glycated hemoglobin test or HbA1c), is an important diabetes blood test used to determine how well your diabetes is being controlled. This diabetes test provides an average of your blood sugar control over a six – to 12-week period and is used in conjunction with home blood sugar monitoring to make adjustments in your diabetes medicines. The HbA1c level can also be used to diagnose diabetes if a value of equal to or greater than 6.5% is found.
Other Diabetes Tests
Along with the hemoglobin A1c test, it’s important for people with diabetes to have a dilated eye exam at least once a year as part of a complete eye exam. This important test can detect early signs of retinopathy, which may have no symptoms at first. A foot exam once or twice a year — or at every doctor’s visit — is also imperative to detect decreased circulation and sores that may not be healing. Early detection of eye and foot problems in diabetes allows your doctor to prescribe proper treatment when it is most effective.
Diabetes Testing in Children
Many children have no symptoms before they are diagnosed with type 2 diabetes. Most of the time, diabetes is discovered when a blood or urine test taken for other health problems shows diabetes.
Talk to your doctor about your child’s risk for diabetes. If your child’s blood sugar tests are higher than normal, but not yet at the level of diabetes (called prediabetes), your doctor may instruct you in specific diet and exercise changes to help your child avoid getting diabetes altogether. Children with type 2 diabetes or prediabetes are almost always overweight or obese.
Understanding Your Diabetes Diagnosis
Diabetes can cause major health problems if you do not keep your blood sugar in check. However, you can stay healthy and feel good despite your diagnosis if you follow your doctor’s recommended treatment plan and maintain a healthy lifestyle. By choosing foods wisely, exercising regularly, maintaining a normal weight, reducing your stress level, and making other modest lifestyle changes, living with diabetes will be easier.

WiseGEEK: What is Fasting Glucose?
Fasting glucose is a blood sugar measurement taken after no food has been eaten for at least 8 to 10 hours. A fasting blood sugar (FBS) test is usually the first kind used when a doctor orders testing for diabetes diagnosis. Diabetics can test their own fasting glucose before breakfast with a home blood sugar monitor.
Most diabetics record their blood sugar readings at different times each day to track their glucose levels overall during a given week. In addition to a fasting glucose, two hours after meals is another common time to check blood sugar levels. Many diabetic people eat five or six small meals throughout the day rather than three large ones to avoid causing big fluctuations in their blood sugars. Exercise can also affect blood sugar — usually causing it to lower. Fasting blood sugars should also be on the low side since there is no food in the body.
During diabetes diagnostic procedures, doctors first usually order an FBS test before having an oral glucose tolerance test (OGTT) conducted. While the FBS tests the body’s fasting glucose on an empty stomach, the OGTT measures its reaction after drinking a controlled amount of sugary substance. The OGTT is usually performed several times in order to get an accurate result. A one-hour OGTT is routinely given to pregnant women to screen them for gestational diabetes. Gestational diabetes occurs in pregnancy and typically presents as high blood sugar levels.
A state of high blood sugar is called hyperglycemia, while a low glucose level is hypoglycemia. Diabetics may experience a wide range of sugar levels from high to low and this can be extremely dangerous. Drastically low or high glucose levels can cause medical problems or even coma and death. Understanding how the body reacts to taking in sugar as well as its fasting glucose level can help control wide fluctuations in blood sugars for better health outcomes.
FBS and OGTT differ from random blood sugar (RBS) tests. Unlike fasting glucose and sugar tolerance tests, the RBS checks blood sugars at any time. In non-diabetic people, blood sugar doesn’t usually fluctuate as greatly as it does in many diabetics. Normal blood sugar levels are often considered to be about 100 ml or a little higher than that. The goal of monitoring fasting glucose as well as other sugar tests is to better control hyperglycemia, hypoglycemia and diabetes through awareness, diet and/or medication.
7) Fasting glucose is a quite simple test to prepare for, although it does sound quite daunting. All you have to do is fast from midnight until after your scheduled appointment the next day, given that it is not before eight o’clock, or after ten o’clock.
If it is before eight o’clock, you should make sure you have not ate for at least eight hours before your appointment. So, for instance, if your appointment is at seven o’clock in the morning, do not eat after eleven o’clock. If your appointment is at noon, do not eat past four in the morning, although you really should try not to eat after midnight anytime, unless you work third shift or are up the hours of third shift.
You really shouldn’t eat right before you go to bed anyway or any time, as this can increase your chances of gaining weight and having an upset stomach too.
You can prevent or at least lessen your chances of getting type two diabetes by eating healthy most of the time. Staying away from sugar and foods with sugar in them would be a good thing to do too.
6) @geekish – Yes, there are some symptoms of a vitamin D deficiency, although some people do not have any symptoms at all.
The most common symptoms of a vitamin D deficiency are muscle weakness and bone pain and bone fractures. The other symptoms associated with vitamin D deficiency are unexplained depression, persistent fatigue, weakness, mood swings and not being able to concentrate.
Feeling shaky and weak if you only go a couple hours without eating could be a lot of different things, but it is definitely serious enough to get to a professional to find out what is going on as soon as possible. Even if you don’t have diabetes, it could be something just as severe or more severe. Go to the doctor as soon as possible!
5) @wander – There are several ways you can test your glucose at home, but all of them require some kind of tools and some know how.
The traditional method of doing this is by pricking your finger with a lancet and getting a reading that way.
A lancet is a small sharp needle and you use that to put a drop of blood on a test strip and then put into a meter to get your reading.
There are newer methods that allow you to prick other areas of your body instead of your finger, such as your thumb or upper thigh. With some of the newest ways, you don’t even have to prick your finger but they use lasers and electric currents.
I really don’t know how these newer methods work, and how you begin using them, I just know there are other options available.
My mother has had diabetes for many years, and it gets really hard to keep pricking your finger over and over again, but she is able to get accurate readings this way.
Once you get the hang of it, it is not hard, and you don’t have to run to the doctors office every time you need check your levels.
If you want it to be a fasting check, just make sure you haven’t eaten for at least 8 hours before you check it. Otherwise you can check it during the day to make sure you are staying where you need to be.
4) I feel as though I may need a fasting glucose test. Lately I have been getting very weak and shaking uncontrollably if I go too long without a snack or something. When I mean too long, I mean around two hours, nothing drastic like five hours or all day or anything.
The reason why I am extra alarmed is because I dated someone with type one diabetes before and he would get weak and shaky if didn’t eat a snack within a couple hours. He also, a couple times, got so bad that he totally lost control of his mind and body, and collapsed on the floor. I definitely do not want this to happen to anyone, me included.
I guess I should go to the doctor and get an all-inclusive physical, although I got one earlier this year. The previous physical showed I have a very low Vitamin D count. I take Vitamin D supplements now. Does anyone know if a lack of Vitamin D has any symptoms? If so, what are they?
3) Is it possible to do a fasting glucose reading at home with your own blood sugar monitor? Or can this test only be performed at a doctor’s office?
I live quite far from my doctor’s office and would like to do a fasting blood glucose test without having to go all the way to her office. I am prediabetes and want to see if the dietary changes I’ve been making have helped get my blood sugar levels under control.
I am worried that despite everything I have done I will still have elevated fasting glucose levels and be stuck on the same diet forever. I really want my life to get back to normal.
2) @popcorn – My mother has Type 2 diabetes and it can be a really difficult medical problem to deal with. If you are taking a fasting glucose test you should know that the normal fasting glucose range is under 100 mg/dL, and those with fasting levels between 100 mg/dL to 125 mg/dL are considered to be prediabetes.
If you find yourself worried about food, just stop eating sugary things. You need to eat healthy and not starve yourself. If you do have prediabetes it can often be controlled with changes to diet. I would talk to your doctor after your test and figure out exactly what is going on with your body.
1) My doctor has asked me to undergo a fasting blood glucose test later this week and I am feeling a bit nervous. What is a normal fasting blood glucose level?
Lately I have been urinating a lot and feeling really irritable after eating, so my doctor thinks I may have diabetes so he is making sure I get all the tests I need. I have actually been scared off eating and haven’t been having much since he told me I could have such a terrible disease. I am wondering what I should eat until the fast before the test? Do you think that just going vegetarian would help me feel better?
